Our team is expanding a cloud-based platform that automatically classifies contracts, pleadings, and other legal papers the moment they’re uploaded. I need a senior full-stack engineer who can design, train, and deploy the classification models while wiring them seamlessly into both the frontend interface and the backend services. Here’s the current landscape: • Frontend: React + TypeScript with a clean component library. • Backend: Python (FastAPI) micro-services, PostgreSQL, and a message queue for heavy jobs. • Tooling already in use: Docker, GitHub Actions, AWS S3/Lambda. Your mission is to deliver an end-to-end document-classification workflow that fits this stack—model creation, API endpoints, UI hooks, and monitoring. Clear, well-tested code and concise technical documentation are required so our in-house counsel can trace how each document is routed. When you apply, point me to past work that proves you have shipped similar AI classification or NLP features inside production web apps; links, repos, or live demos are preferred. No lengthy proposals—results speak louder. If you’re comfortable owning the ML pipeline and the surrounding product code, let’s talk timelines and milestones.
