21 years. 21 SaaS built. 50+ companies served. When you need consultancy, you get a hands-on Technical Director who writes the code, designs the architecture, and delivers — not just advice.
Not a slide deck. Not a committee. One senior engineer who does the five jobs — from architecture to deployment.
System design, database schema, API contracts, infrastructure blueprints. Decisions grounded in 21 years of building production systems.
Backend, frontend, database, infrastructure — all from one person. No handoff delays, no lost-in-translation specs. Golang, PostgreSQL, HTMX.
112 screens in 60 days. 15k lines of production Golang in 9 months. Full products shipped at a pace that usually requires a team.
Platform architecture, "four nines" high availability, load testing, monitoring, on-call. 10+ servers managed simultaneously at Greenflex.
Team supervision, feasibility analysis, tech watch, calendar management. Leadership that writes code, not just emails.
LLM benchmarks, chatbot development, AI architecture. Masters in Robotics & AI from Arts et Métiers and the Sorbonne.
