Linux Jobs

I’m expanding an embedded Linux platform that runs on the AM335x-based BeagleBone Black and I need an engineer who already knows their way around the board. The work spans kernel configuration, real-time GPIO toggling, PRU firmware tweaks, and device-tree overlay edits, all deployed on Debian/Ubuntu images via remote workflows. Day-to-day coding will be done in Python for the high-level hardware control layer, so fluency there is essential; C/C++ knowledge for the lower-level pieces is a plus but not mandatory. You will be working with: • GPIO • I2C • SPI The schedule is flexible—part-time or full-time—and everything is handled remotely. When you apply, focus on your BeagleBone experience: link to relevant GitHub repos, forks, demos, or shipped pr...

I want to turn my Raspberry Pi 5 (16 GB) into a self-contained 4G gateway that also broadcasts Wi-Fi, giving me both access-point and router functionality in one box. The hardware already on my bench includes: • PCIe-to-USB 3.2/M.2 HAT+ carrying a SIM7600G-H 4G module • Waveshare UPS HAT (E) for power resilience Your task is to supply either a pre-built image or an installer/launcher script that boots straight into a reliable router environment. I need advanced administration—custom firewall rules, NAT, DHCP scopes, VLANs, the works—plus real-time bandwidth monitoring and basic historical usage charts. Think more OpenWrt-style flexibility than a “set-and-forget” wizard. Key behaviour I expect: • Automatic detection of the SIM7600G-H over USB 3....

I run BlueStacks on a Windows machine and need every session to start with a completely fresh, non-repeating IP address so I can avoid IP bans. I’m looking for someone who can guide me to the right VPN solution, set it up, and prove that the emulator receives a new IP each time it connects. You may suggest either paid or free providers—as long as the rotation is automatic, the pool is large enough to minimise repeats, and performance stays usable inside BlueStacks. Once we agree on the provider, I’ll need you to configure it on my system, walk me through any required settings inside both Windows and BlueStacks, and verify together that multiple reconnects always yield unique IPs. Acceptance criteria: • BlueStacks traffic consistently routes through the VPN. • ...

I need a developer who can wrap Threadfin inside a rock-solid Docker architecture so I can manage and distribute IPTV playlists for more than a hundred individual users without ever touching an IPTV panel or running my own streaming server. Here is what the finished solution must do for me: • Hold one master channel and EPG configuration that I can tweak in a single place. • Spin up an isolated copy of that config for every new user, each bound to its own port and paired with the user’s unique IPTV credentials. • Provide a small shell or Python script that lets me create, list, or remove users in one command. • Run smoothly on Docker (compose or Swarm is fine) and stay easy to back up, upgrade, or migrate. • Scale gracefully past 100 users with m...

My Vicidial instance on a Linode VPS has suddenly dropped off-line. The hostname no longer resolves and I cannot reach the machine even by its IP, so I’m convinced this is a network-level problem rather than a recent configuration change—nothing has been touched for weeks. I need someone who is comfortable diving straight into a production Linode, checking DNS records, firewall rules, networking interfaces, and Vicidial/asterisk services to get everything visible on the internet again. Root SSH will be provided the moment you’re ready to start; the goal is minimal downtime and a clear explanation of what went wrong so it doesn’t repeat. Deliverable: • The server’s web and SIP services must be reachable externally at (and by direct IP). • Vicidi...

Across my web applications, internal network infrastructure, desktop endpoints, company phones, and public social-media profiles, I need a full-scope security examination. The engagement must blend hands-on penetration testing with a structured security audit so that both technical weaknesses and policy gaps are captured in one clear deliverable. Scope • External and internal testing of web apps, network segments, desktops, mobile devices, and social-media assets • Manual and automated discovery using industry-standard tools such as Burp Suite, Nmap, Metasploit, Wireshark, Nessus, Kali Linux, and OSINT/social-engineering toolkits • Coverage of OWASP Top 10, SANS Top 25, common mobile attack vectors, and configuration hardening checks Deliverables • Comprehen...

I already have Terraform code auto-generated by an AI assistant called “Kiro,” a Bitbucket repo that holds it, and a Jenkins server ready to run the builds. The goal is simple: when I merge to the main branch, Jenkins should read an Excel sheet that lists AMI ID, instance type, subnet, VPC, tags, and any other parameters, then hand those values to Terraform and cleanly create or update the corresponding EC2 instances on AWS. Where I need help is deployment and infrastructure setup. I’d like to pair program so we can: • Wire Bitbucket, Jenkins and Terraform together, including a secure backend (preferably S3 with state locking). • Automate extraction of the variable set from Excel—whether that’s a small Python helper, Terraform external data sourc...

I’m running an Ubuntu droplet on DigitalOcean and simply need to power-cycle it from the control panel. I have already combed through the droplet settings menu and the usual power options but still don’t see anything labeled “power-cycle,” “reboot,” or similar. What I need from you is a quick walkthrough (screenshots, short screencast, or a concise set of steps) that shows exactly where the power-cycle action sits in the current DigitalOcean interface and how to trigger it safely. If the option has been moved, renamed, or now lives under a different tab, please point that out so I can repeat the process on other droplets later. A short session over chat or a brief annotated guide is perfect—as long as I end with a successfully rebooted droplet th...

My Magento 2.4.7-p1 installation has picked up malware located in /aregowe/magento2-module-polyshell-protection/. The server hosts five separate storefronts that all run off the same codebase, so the infection must be eliminated everywhere without disrupting live sales. I already have recent, working backups, so you can feel free to revert any file if needed. I am not looking for a full security audit right now—just a thorough, targeted cleanup.

More details: What kind of server environment do you want? Survival Do you need any specific plugins or additional mods installed along with your modpack? Yes, additional mods Which hosting platform do you prefer for the Minecraft server? curseforge

My Asus X1505Z, fitted with an M.2 SSD, is locked by BitLocker after a former employee enabled encryption and left without sharing the password or recovery key. I must regain full access to every file on the drive—there are no backups to fall back on—yet I would like the work carried out entirely through remote means. I do not have the PIN nor the recovery key for the laptop. The device was not a part of active directory and the person used his own Microsoft account. To my knowledge it is locked with PIN and TPM. I can allow remote access via Anydesk as i can boot it to Hiren or Medicat via usb. I am willing to obtain any required software in support of this recovery within reason (not more than the cost of the freelancer fee) If you have proven experience in Windows Bi...

I have an existing Python-based automation script that runs smoothly on my local machine, but I now need a small tweak plus reliable deployment on my AWS account. The tweak: the script requires one additional feature that we’ll clarify together once you’ve reviewed the code. It should remain lightweight, keep the current logic intact, and follow the same coding style. The deployment: after the update, I want the script running on AWS—ideally as an EC2-hosted service or Lambda function, depending on what you find most efficient. The instance should auto-start on reboot and log to CloudWatch (or a similarly straightforward option) so I can monitor it without extra overhead. Deliverables (acceptance criteria) • Updated Python 3.x script with the new feature fully i...

I’m ready to roll out Odoo Enterprise on-prem but I would like an expert beside me for the actual installation step, what I need right now is someone who knows the quirks of the Enterprise build and the usual Python/odoo user setup to make sure the first launch goes smoothly. We’ll work together over a live screen-share (or, if you prefer, a concise step-by-step document followed by a quick Q&A call). By the end of the session Odoo should be running as a service, reachable from a browser, and ready for me to dive into further configuration on my own. Key points you should be comfortable with: • Installing Odoo Enterprise • Docker That’s the scope—straightforward and focused on the installation itself. If you’ve done this a dozen times already,...

I need a physical, dedicated machine hosted in a Hyderabad-based data center that can consistently deliver very low latency to Telangana government domains. The server must run Linux and come with a static public IPv4 address; I will manage it over SSH, so no control panel is required. Network requirements are strict: stable, direct routing through a major Tier-1 Indian carrier—Sify, Airtel, Tata, or NTT are ideal—and the link should hold a low TTFB under normal load without frequent path changes. The setup is for performance-critical browsing and API calls, so rock-solid connectivity is essential. To help me verify suitability, include the following in your reply: • Exact facility name and street address in Hyderabad • Upstream ISP/carrier and routing details &...

I am looking for a Google Workspace expert to migrate two complete email accounts from our current Google Workspace domain to a newly established Google Workspace account. The goal is a "mirror" migration where all existing emails, including attachments and metadata, are moved without any data loss.

I need a small, reliable utility that connects to the official WhatsApp Business API, pulls the full text history from both group and individual chats, and saves every message (plus date, time, sender, and chat ID) into a clean CSV file. Key points • Scope is message extraction only—no sending, no marketing logic. • Both group and one-to-one threads must be handled in the same run. • Output must be a single CSV per execution, ready for import to spreadsheets or a data warehouse. The solution can be written in Python, Node.js, or any language you are confident will compile on a standard Linux server. Please include clear setup instructions and a brief README so I can change credentials and select date ranges myself. Acceptance criteria – Connects ...

I’m ready to roll out several improvements to our live Avaya IVR and want someone who already knows their way around Avaya Experience Portal / Orchestration Designer and VoiceXML. The system is stable today, but the menu tree is dated and callers are not always routed to the right skill group. Here’s what I need done: • Add the new menu options that I’ll supply (scripts and prompts are finished and approved). • Fine-tune voice-recognition so callers can speak choices naturally; experience with Nuance or the built-in ASR tuning tools will be valuable. • Adjust the call-routing logic so selections flow to the correct queues without the current detours. You’ll receive: – Current IVR application files and design documents. – Ac...

Vicidial is already live on our cloud server; what I need now is an on-site engineer in Hyderabad who can bridge it to a 32-port Dinstar GSM gateway sitting in our office. Your task is strictly configuration and testing—no fresh installs. Scope of work • Register the Dinstar gateway as a SIP trunk inside Vicidial, keeping a close eye on call-quality parameters and full compatibility with the gateway. • Analyse the current router, decide which ports must be opened, then set up forwarding so traffic reaches the cloud server cleanly. No predefined template exists, so you will determine the rules and apply them. • Run end-to-end test calls, troubleshooting the single audio problem we’ve seen so far: distorted sound. I expect clear audio on both legs before sign-off....

My Magento 2 store is already live on a single Nexcess PaaS environment, but every update still goes through a manual FTP-style process. I’d like to replace that with a clean GitHub Actions pipeline that can build, test, and deploy with zero downtime while giving me an easy path to add automated tests later (none exist yet). Here’s what I need you to craft: • A GitHub Actions workflow that checks out the repo, resolves Composer dependencies, runs Magento setup tasks (setup:upgrade, static-content:deploy, di:compile), manages cache/maintenance mode, and deploys to Nexcess over the recommended method (SSH/SFTP or Nexcess API). • Separate branches or job steps that let me push safely to a staging slot before promoting to production, even though Nexcess currently host...

Our customer-facing login portal suddenly stopped working right after a previous freelancer performed AWS cost-optimization tasks (Reserved Instances, auto-scaling tweaks, and some security-group changes). Users enter their credentials, hit “Sign In,” and are immediately bounced back to the login screen with no specific error—so sessions clearly aren’t being established or persisted. Here’s what I need from you: • Diagnose the exact cause of the loop (session handling, load balancer stickiness, Cognito/IAM policy, or any other AWS-related misconfiguration). • Restore normal authentication flow so clients can reach their dashboards again. • Provide a concise technical summary of the root issue and the steps you took, so we can avoid a repeat...

I need a fully-async Python 3.11+ pipeline that turns a live phone call into a smooth, sub-2.5 s p50 conversational loop. Here’s the flow I have in mind: a Twilio SIP trunk delivers the RTP stream to a WebSocket bridge; LiveKit Agents SDK manages the media session; Deepgram Nova-3 handles streaming STT; the running transcript feeds Claude (with tool-use enabled); Claude’s text comes back out through ElevenLabs Flash v2.5 for TTS and streams to the caller in real time. What I need from you is a working reference implementation, instrumented and tuned so I can see latency at each hop and fine-tune Voice Activity Detection thresholds. The code must retry transient errors, log everything that matters, notify the caller gracefully on trouble, and, if the Sonnet tier fails mid-call...

I need a specialist to dive into my existing ECAAM environment and complete a full system configuration. The focus is on three core components: • Database – configure schemas, connections, and any tuning that will keep queries fast and reliable. • Network settings – set the correct ports, security rules, and routing so every ECAAM service communicates smoothly inside our LAN and from remote locations. • Software modules – verify each installed module, adjust its settings, and make sure dependencies are resolved. The installation itself is already in place; what I am missing is a clean, production-ready configuration that I can rely on without constant patch-ups. You are free to use the tools you’re most comfortable with—command-line, GUI u...

I need to interact with my custom Linux-based application through four independent sessions that appear side-by-side inside a single browser tab. When I open the page I should see the application running in four resizable panes (a 2 × 2 grid is fine), each session operating completely isolated from the others, yet streamed over one remote-desktop–style connection. The solution may build on RDP, VNC, SPICE, WebRTC, or any comparable protocol; what matters is low-latency keyboard and mouse responsiveness and a clean way to embed the composite view in an HTML page without requiring plugins. Server components will run on Ubuntu 22.04 LTS, so anything you write or configure must be compatible with that environment. Client side should work in the latest Chrome and Firefox. Deli...

We are migrating and hardening a healthcare-oriented web platform on AWS. We need an engineer (or small team lead) who can discover the current environment, design a safe cutover plan, execute migration and modernization (lift-and-shift where appropriate, refactor where required), and leave us with documented, automated operations (IaC, CI/CD, observability, backup/DR, security controls). What I expect from you • Review the current EC2, RDS, and S3 configurations, then right-size or redesign them for lower cost without hurting performance. • Implement cost-saving measures such as auto-scaling policies, spot or reserved instances, storage life-cycle rules, and any other best-practice features you recommend. • Harden the setup with sensible security settings and monitor...

I need a complete, self-hosted email solution for a small business that I’ll be running on a Linux server (Ubuntu or CentOS—whichever you feel is best for the chosen stack). The key objective is to move away from third-party providers and gain full control over our mail, security, and data compliance. The specific mail-transfer agent is still open: Postfix, Exim, Mailcow or another proven alternative can be used, as long as the end result is stable, secure, and straightforward to maintain. What I expect from you: • A production-ready mail server configured with SMTP, IMAP/POP3, spam and virus filtering, DKIM, SPF, DMARC, and valid SSL/TLS certificates. • Simple webmail access and clear instructions so that I can add domains, users, and aliases without touching...

I need an experienced systems professional who can take ownership of my production servers from the ground up. The job starts with a full audit of the existing Linux stack (Ubuntu 22.04 on AWS EC2), then moves into tightening every layer—optimising configuration, hardening services, and putting robust security controls in place. What matters most to me is confidence that the machines are patched, performance-tuned, and continuously protected. After the initial hardening you will set up real-time monitoring and alerting (Prometheus + Grafana is currently installed but not fully wired), document a clear maintenance schedule, and remain on hand for rapid incident response. Deliverables • Comprehensive audit report with recommended fixes • Implementation of agreed configu...

I have a custom-built e-commerce store hosted on Hostinger. I already own the domain; what’s missing is a proper server-side configuration so the URL loads the storefront and every feature can read and write to my MongoDB database. Here’s the situation: • The files are on my Hostinger VPS. • The domain’s DNS is active but not yet pointing to the right place. • The store’s back-end expects a live MongoDB connection (I have connection string and credentials ready). Your task is to: 1. Configure the domain and any necessary A/AAAA/CNAME records so the site resolves cleanly over HTTPS. 2. Adjust Hostinger’s server settings (Nginx/Apache, SSL via Let’s Encrypt, or whichever stack you prefer) so requests hit the correct build folde...
