Designing and delivering production-grade web systems — SaaS platforms, ERP integrations, REST APIs, and enterprise applications.
Backend Software Engineer with 6+ years of experience building production-grade web systems. Served as the sole remote backend engineer for a French digital agency (SS2i Services) — delivering 20 production projects across 960 tracked hours with a 93% task completion rate over 20 months.
I focus on clean architecture, scalable database design, real-time systems, and third-party API integrations. Currently building AI-powered backend features using OpenAI and Anthropic APIs. I work effectively in async, distributed teams across European time zones.
"Long-running, deepening engagement — what started as one major platform expanded organically into 20+ projects over 20 months. 93% of assigned tasks delivered across 960 hours of tracked work. The kind of collaborator that any team is happy to keep working with for years." — Samuel Legros, SS2i Services (France) · May 2026
