Fabrice G.

I design and develop complete digital products — from turnkey SaaS to autonomous AI agents.

Technical co-founder of a startup, I built 2 SaaS products from scratch, deployed in production with real users. I don't do mockups or disposable POCs: I deliver robust, tested, documented, and scalable systems.

What I build:

→ Complete SaaS — Backend + frontend + auth + payment + deployment architecture. My 2 products in production (PayloadDiff and Leak Detector) are proof of this.

→ High-performance APIs — REST APIs with FastAPI, third-party integrations (Stripe, webhooks, partner APIs), async architectures with Celery and Redis for background processing.

→ AI Agents & LLM Integrations — Integration of Claude API and GPT into concrete business workflows. Not a gadget chatbot: AI that produces measurable results (automated analysis, structured content generation, assisted decision-making).

→ Automations — Automated workflows, background workers, data pipelines, complex task orchestration. What took your teams hours now runs automatically 24/7.

My stack:

Python 3.12 · FastAPI · Celery · Redis · Next.js 14 · TypeScript · Tailwind · Supabase PostgreSQL · Stripe · Railway · Vercel · Claude API · Playwright · Sentry

My method:

Short sprints, frequent deliveries, visibility at every stage. Documented, versioned, tested code — no hidden technical debt.

Based in Marseille — available remotely for all of France.
