I need a seasoned DevOps engineer to stand up and run the entire backend that powers our transport-tracking platform. The system has to ingest GPS data from roughly 300 buses every 10 seconds, which works out to about 2.5 million write events each day, so resilience and low-latency processing are critical. Platform & core stack • Cloud: we’ll build everything on AWS (EC2/ECS/EKS, VPC, IAM, S3, Route 53 ‑ whatever fits best). • Messaging: Redis is my first choice for the real-time pub/sub layer, though I’m open to Kafka if you can justify the trade-offs. • Monitoring: Prometheus for metrics, with dashboards in Grafana; CloudWatch can complement for AWS-native alerts and logs. Key things I expect you to deliver • A fully scripted, infrastructur...

Backend Developer This person builds the core system and integrations. Job Title Backend Developer – Transport System APIs, GPS Integration, Ticketing Platform Job Description Project Overview We are developing a hybrid bus transport management platform that integrates GPS tracking with a custom passenger services system. The system will initially support 250–300 buses and provide real-time telemetry, digital ticketing, and operational monitoring. The architecture combines an existing white-label GPS tracking platform with a custom backend system to support passenger services and transport operations. Responsibilities • Design and develop backend APIs • Integrate white-label GPS tracking system • Implement real-time bus location ingestion • Develop dig...

I have an ESP32 dev board on my bench and need it turned into a compact sensor hub. The entire focus is sensor integration—specifically motion & proximity plus light & sound. Some of the devices will be hard-wired to GPIO pins while others should connect wirelessly, so the firmware must handle both connection paths seamlessly. Here’s exactly what I need delivered: • Well-commented source code (Arduino-ESP32 or ESP-IDF) that polls each sensor, filters noise, and publishes readings over Serial and MQTT. • A clear wiring / pin-out diagram for the hard-wired sensors. • Configuration notes that let me pair or re-pair any wireless sensor modules. • A short README covering library installs, flash commands, and expected output. Acceptance criteri...

I am building an end-to-end IoT monitoring system and need help finishing three tightly-connected pieces: • A Python script on a Raspberry Pi that collects sensor readings and publishes them to an MQTT broker. • A Django micro-service that preprocesses those messages before handing them to a Laravel / MySQL backend, where devices and users are registered and authenticated. • A React Native mobile app that runs on both iOS and Android and subscribes to the same broker for real-time data display. The mobile front-end’s first milestone is a clean dashboard that streams temperature, humidity, device operational status and any other sensor readings the Pi sends. Data has to update instantly without manual refresh, using MQTT over websockets. Once that foundation ...

I’m looking for a developer who can deliver a complete web application that lets our team both monitor and control a fleet of industrial-grade IoT machines from any browser. Tech stack Front end: React (ideally with hooks and functional components) Back end: FastAPI (Python 3.11 preferred) Core objectives • Real-time status updates – live metrics pushed to the UI with WebSockets or a comparable streaming method. • Historical performance data – charts or tables that let supervisors review past readings over selectable time ranges. • Remote control – authenticated users must be able to trigger predefined commands (start, stop, reset, change set-points). Key deliverables 1. FastAPI service exposing REST endpoints and a WebSocket channel,...

I need a full-featured central monitoring application that talks seamlessly to Tuya-based panel alarm systems and Tuya cameras. The core requirements are: • Real-time alerts whenever a sensor, zone, or camera triggers • Live and archived video surveillance from all registered Tuya cameras • Continuous system-health monitoring so I can see device status, connectivity, and battery levels at a glance • Complete alarm-system arm, disarm, and event handling from the same dashboard The solution must run on a Windows server yet present everything through a clean, secure web interface that any modern browser can open—no thick desktop client. Please rely on Tuya’s official API/SDK (MQTT, HTTPS, WebRTC, etc.) so future firmware updates remain compatib...
