Docker Jobs

I have a working—but dated—application from 2019 that now needs a full refresh. The goal is to reconstruct the entire stack in Python with FastAPI as the back-end framework, then pair it with a clean, minimalistic front-end and a companion Android app. Back-end • FastAPI should expose a well-documented REST layer that mirrors the logic of the original codebase, yet follows today’s best practices (typed models, async handlers, JWT-based auth, etc.). • Core services must cover secure user authentication and real-time GPS tracking, with endpoints ready for push-notification triggers. Front-end The web interface should be modular—think component-driven architecture that lets me swap or extend modules later without touching the whole UI. A minimalistic ...

I need a custom-built, calculation-driven site that lets me upload a short video of a metal rod, bar, or similar object. In every clip I will have placed a coin of known diameter and thickness beside the item. Your job is to turn those frames into a 3-D model and return the precise volume (mm³ / cm³) of the target object. Core workflow • Video (or image sequence) upload • Automatic frame extraction and calibration against the coin’s dimensions • Photogrammetry reconstruction in the browser or on the server (OpenCV, WebGL, Python + OpenMVG/Meshroom/Metashape CLI—use whichever stack you’re fastest with) • Volume calculation and a clean numeric report, downloadable as JSON or CSV, plus a thumbnail of the 3-D mesh Key requirements &bu...

I need a robust, self-hosted scraping tool that can reliably collect product details and customer reviews from Amazon, Walmart, Lowes, Home Depot, Leroy Merlin, and Elektro Wandelt. The crawler must run once a month without triggering the anti-bot systems these sites use, so smart throttling, proxy rotation, user-agent randomisation, and solid CAPTCHA handling are essential. I will trigger the run manually (CLI or simple dashboard is fine) and receive structured output—CSV and JSON are both acceptable—with clear field names for SKU, title, price, availability, rating, review text, and timestamps. Source code should be clean Python (Scrapy, Playwright, Selenium, or a comparable stack), containerised for easy deployment, and accompanied by a short README that explains setup, p...

I have a Java Spring Boot service that’s production-ready and containerised. What I need now is a smooth rollout to a Kubernetes cluster running on AWS. You’ll provision the cluster, create the Kubernetes manifests (Deployment, Service, ConfigMap/Secret as needed) and make sure the pods connect reliably to a MySQL database. All images are already built and stored in my private registry; your job is to pull them into the cluster, wire up the environment variables, set up any required IAM roles and confirm the whole stack starts cleanly. A brief, step-by-step README of what you’ve done and the kubectl commands to verify the rollout will be the final hand-off.

I have a Google Colab notebook that trains and serves a PyTorch machine-learning model. I now need that work packaged as a lean Docker image that can be dropped straight into a serverless container platform (e.g., Cloud Run, Lambda Container, or similar) without extra tweaking. The brief is simple: start from the existing notebook, install only the core PyTorch stack and essential runtimes, and generate a Dockerfile that builds cleanly on any standard x86-64 host. No extra libraries are required beyond the usual PyTorch and Python basics, so please keep the image footprint as small as practical. What I expect from you: • A working Dockerfile (plus any minimal entrypoint script) that launches the model for inference. • Clear build & run commands, preferably in a short RE...

Project: API Refactor & Performance Optimization (FastAPI / Postgres / Async Architecture) We’re seeking a Senior Backend Engineer or small elite team to transform a legacy monolithic endpoint into a modern, high-performance, event-driven API layer. This is not a simple port—it’s a surgical re-architecture focused on responsiveness, scalability, and clean contracts between frontend and backend. Context We’ve migrated a .NET monolith to Python + FastAPI. The current system works but suffers from latency caused by an “all-in-one” endpoint. The goal is to decompose this endpoint, introduce asynchronous orchestration, and implement database- and API-level optimizations to achieve sub-second response times. Key Deliverables Redesign existing endpoint...

Seeking an expert to migrate UISP data from a local Docker environment to a cloud-based instance in order to integrate with Ubiquiti's Payment Gateway. The migration involves ensuring all data is successfully transferred and accessible in the cloud version. I've attempted to restore a large backup file from the local instance to the cloud-based UISP instance several times. While the restore process seems to complete successfully, no data is transferred to the cloud version, leaving everything empty. I’m wondering if the Docker setup on the local instance is causing issues with the migration, or if there’s a specific import/export procedure I’m missing. Deliverables: - Migrate UISP data from local Docker to cloud - Ensure successful data transfer and accessibili...

The project is to build a dedicated inventory management system that sits at the centre of our operations and talks directly to our e-commerce platform. Real-time inventory tracking across every SKU is essential so that stock levels adjust the moment an order is placed, edited, cancelled, or a return is received. Alongside this live feed, the system must generate clear reporting and analytics—sales velocity, low-stock alerts, ageing inventory, and the usual export options (CSV/PDF) for finance and purchasing teams. Seamless integration with our existing online store is a must. Whether you achieve that through REST, GraphQL, or webhooks is up to you, but the synchronisation window may never exceed 60 seconds. Role-based access, an intuitive web dashboard, and clean code that can be c...

I need a turnkey ANPR solution that watches the cameras at both my entrance and exit lanes, recognises every plate—regular vehicles as well as emergency units—and fires off an instant, time-stamped notification to me on Telegram and WhatsApp simultaneously. Feed: one IP cameras already in place (RTSP). Expectation: the system detects the plate, confirms its characters with high confidence, tags the direction (IN or OUT), and sends a concise message such as “IN • MH12AB1234 • 2024-06-04 14:21:08”. I’m open to any solid stack—OpenCV, YOLO, EasyOCR, OpenALPR, PlateRecognizer API, or a custom-trained model—as long as it runs reliably on a modest Linux box (Ubuntu 22.04) and can be containerised for easy redeployment. Deliverables ...
