    have a completed AI-powered maintenance management SaaS platform that needs a specialist to take it from near-complete to fully production ready. The codebase is clean, well-structured, and built on React + TypeScript + Supabase. A detailed technical handoff document exists that outlines every remaining gap, every relevant file, and the estimated effort — so you would not be walking into the unknown. The work is not about building anything new. It is about closing specific, well-defined gaps: deploying migrations, hardening security configuration, setting up CI/CD, wiring server-side jobs, and connecting the AI layer to live data. Everything is already scoped and documented. A couple of quick questions before we go further: Are you currently available to take on a new proje...

The core focus is on the upload-and-share flow; advanced authoring tools are not required at this stage.

    ...What I need from you spans the full development cycle: solid, well-commented code for data ingestion, preprocessing, model training, evaluation, and automated deployment; guidance on architecture and design choices as we iterate; and a polished, presentation-ready knowledge base that explains every component for future hand-off or scaling. A responsive web dashboard (built, for instance, with React or another modern framework) should graph live metrics, highlight anomalies, and push configurable alerts.
