Stephane D.

I've been building web and mobile applications for 25 years — from one-day MVPs to platforms processing $3M+ annually. I run a 10-15 person dev agency, so you get senior-level thinking with team-level capacity when you need it.

WHY I GET JOBS: Clients say I communicate better than any developer they've worked with. Non-technical founders understand everything I say. I don't just build what you ask for — I help you figure out what to build and why.

What sets me apart:

✅Product thinker, not just a coder — I contribute to UX, business direction, and architecture
✅AI & Data Engineering: AI/ML/Gen AI + Data ETL Pipelines, RAG chatbots, AI agents, MCP servers
✅Complex payment systems: Stripe, Authorize.net, Braintree, installment plans, commissions, refunds
✅Long-term partnerships — most of my clients have been with me for years
