About Thibault Daravann

Thibault Daravann P.Status: Offline
Full-Stack JavaScript Developer (React/Node.js) - AI Specialist
Bezons, France - 5:13 pm local time
Full-stack JavaScript developer (React / Node.js) with 5+ years of experience building production web applications — including real-time systems (chat, audio, video) with custom, configurable admin interfaces and AI bot integrations. Sole owner of a real-time CPaaS platform connected to Rainbow (Alcatel-Lucent Enterprise): technical design, development, deployment and maintenance.

I also work with Python, Redis and NATS when a project calls for it.

What I can help with:
- Building or extending web applications (SaaS, dashboards, back-office tools)
- Reliable Node.js APIs connected to a React frontend
- Integrating AI (OpenAI, Claude...) into an existing product
- Quick fixes and unblocking urgent issues on existing codebases

New to Upwork — not new to the field. I pay close attention to my first contracts to build trust with early clients: fast response time, regular updates, clean code delivered on time.

Based in France, working remotely. Available 15+ hours/week (evenings and weekends), in addition to my full-time role. Clear communication, realistic deadlines.
