The target runtime is Amazon EC2, and Jenkins is the continuous-integration engine I would like driving the process. Here is what I need from you: • A complete CI/CD pipeline that triggers on pushes to my Git repository, runs automated tests, builds an artifact, and pushes it to EC2 with zero-downtime or minimal-downtime deployment logic. • Secure, repeatable AWS infrastructure for the pipeline itself—whether that is spun up through CloudFormation, Terraform, or another infrastructure-as-code approach you recommend. • Parameterised Jenkins jobs (or a Jenkinsfile) with clear environment variables so I can promote the same build through dev, st...
I need a seasoned Microsoft Dynamics 365 Customer Engagement developer who can take full ownership of our environment—designing, developing, and continuously improving secure, scalable solutions. The day-to-day work will revolve around three areas: • Customization and enhancements – building new entities, forms, plugins, Power Automate flows, JavaScript, and business rules that follow best-practice patterns in C#/.NET. • Integrations and APIs – exposing and consuming REST endpoints, writing Azure Functions, and wiring everything together through Azure Service Bus, Logic Apps, or similar middleware while keeping performance and security front of mind. • Ongoing support and maintenance – monitoring with Azure DevOps pipelines, troubleshooting issu...
I need an end-to-end, AI-driven test harness wired into our web application. Your first task will be to evaluate the current landscape of intelligent testing platforms—whether that is a SaaS tool with an open API, a self-hosted agent that sits behind an MCP server, or an approach that layers generative AI on top of a browser automation framework such as Playwright or Selenium. Once you have identified the best fit, you will integrate it so the system can: • Navigate our core user flows in Google Chrome and Microsoft Edge • Flag visual and UX regressions, broken links, and layout shifts • Verify functional parity across the two browsers • Generate performance insights when pages are under load and surface bottlenecks in an easy-to-read report Deliverables...
I have the concept, wireframes, and an initial style guide ready; now I need a full-stack developer who can transform them into a production-ready mobile application built with Flutter on the front end and FastAPI on the back end. Core feature set • Every user should be able to create rich pet profiles that store photos, breed info, vaccination dates, and other medical records. • A robust appointment scheduler must let pet owners pick time slots, confirm, reschedule, or cancel directly in-app and receive push/email reminders. • Integrated search will allow owners to find nearby groomers, vets, and sitters, view ratings and written reviews, and book them instantly. Account structure & roles Secure authentication is required. We’ll need at least two clearly...

I need a specialist who can take our existing iOS and Android builds and create reliable Eggplant Functional suites that fully automate the end-to-end user flows. The focus is purely functional testing—no performance or load work—so every script you build should validate real-world behaviour: installation, onboarding, core feature execution, error handling, and logout. You will map the critical paths, write readable SenseTalk scripts, parameterise test data, and organise the assets so they can be triggered from our CI pipeline later on. Clear logging and screen-capture on failure are essential because the results will be reviewed by both QA and product owners. Deliverables: • Eggplant Functional project with modular, well-commented SenseTalk scripts covering all agreed...
I want to build a Codex-style companion that runs inside or alongside ChatGPT and can move from blank prompt to a live product with virtually no guardrails. The assistant must be able to: • Generate production-ready code in Python, JavaScript and Java • Spin up static sites, dynamic web apps and even mobile builds automatically • Detect, explain and patch errors as they appear during compilation, testing or deployment End-to-end automation is paramount: once I describe the idea, the AI should wire up repos, provision hosting, push to production and hand back URLs or installable builds without human intervention. Any solution—fine-tuning an existing LLM, chaining models, or wrapping bespoke tooling—is acceptable as long as it keeps the conversation flow in...
I’m looking to bring a seasoned DevOps mind on board to tighten up our AWS workflow. The immediate focus is three-fold: 1. Turn our manual deployments into a clean CI/CD stream. We already run Jenkins, so I need multi-stage pipelines built and wired to our repos, complete with automated testing and blue-green or canary releases where it makes sense. 2. Express the entire stack in Terraform. Every VPC, subnet, security group, EKS cluster, and supporting service should be reproducible from code and kept in version control so we can spin up identical environments on demand. 3. Add robust monitoring and logging. Think CloudWatch metrics and logs, sensible alarms, dashboards, and log retention policies that let the team trace issues quickly without drowning in noise. You&rsquo...
I have a micro-service–based application already running on Azure and need a full DevOps pipeline that carries each change from commit all the way to live monitoring. The work must cover three clear stages—Build & Test, Release & Deploy, and Monitor & Operate—so that every push is automatically built, validated, shipped, and observed inside the Azure ecosystem. What I expect you to put in place: • A YAML-driven CI flow in Azure DevOps (or GitHub Actions if it fits better) that restores dependencies, runs unit/integration tests, and packages each microservice as a Docker image, pushing the result to Azure Container Registry. • A CD flow that promotes images through dev, staging, and production with manual approval gates, deploying either to AKS...
My SaaS platform already runs on FastAPI with SQLAlchemy 2.0, Alembic, and Postgres. The foundations are solid, yet several partially built features still need to reach production-ready quality, and each change must respect strict multi-tenant data isolation. Needed Tasks Scope • Finish the outstanding endpoints and background jobs that were started but never wired end-to-end. • Keep every migration in sync through Alembic and validate that tenant-level schemas remain untouched by other tenants’ data. • Refactor any SQLAlchemy 1.x patterns that may still linger so we are fully 2.0-compliant. • Add the missing unit and integration tests (pytest) to confirm isolation, correctness, and performance before release. Acceptance Criteria 1. All new or complet...

Ideal Skills and Experience: - Strong expertise in Azure DevOps - Experience with Git repositories, AKS, Helm charts, and Terraform - Familiarity with security practices in CI/CD environments - Ability to document processes and provide knowledge transfer Looking for someone who can work efficiently and communicate effectively.
I need an experienced automation engineer (around 4-10 years working with Playwright in both JavaScript and TypeScript) to build and maintain a solid test suite for my web application. Scope • Target platform is strictly Web. • The suite must run reliably on Chrome and Firefox—cross-browser parity is essential. • Coverage spans all three layers: end-to-end flows, critical integration points, and a handful of fast unit tests around our helper utilities. Day-to-day you will wire Playwright into an existing Node/TypeScript repo, design a clean folder structure, and implement sensible fixtures, mocks, and test data factories. The code must be readable, reusable, and commit-ready with meaningful assertions and screenshots on failure. I will also rely on you to add...

I’m looking for an India-based freelance developer who can dive straight into our React + frontend, diagnose the issues users are reporting, and push clean, well-reviewed fixes. The codebase is already in production, so you’ll spend most of your time tracing bugs, tightening TypeScript typings, and making sure every pull request ships without breaking existing flows. You’ll work against an API layer built with FastAPI, SQLAlchemy and PostgreSQL, deployed on AWS (ECS / Fargate, Lambda, SQS, API Gateway) and wrapped in Docker with a CI/CD pipeline on GitHub. While your day-to-day focus stays on the browser side, familiarity with the wider stack will help you understand edge-cases and spot integration problems quickly. Deliverables for each sprint • Reproduce and d...
