Flutter Expert, with double expertise in Generative AI (Claude / Anthropic).
5 yearsof mobile development.
9 cross-platform applicationsin production.
⚙️ AndLLM integrationsin a production environment.
My latest achievement: Rociny, an influencer marketing platform integrating payments, notifications, geolocation, and invoicing.
Who I work with:
→ SMEs / Startups: a single point of contact who handles the app from A to Z. No intermediary agency, no team to coordinate, no inflated quotes. You talk to the person who codes.
→ Large Corporations: a senior developer who integrates into your processes (code review, CI/CD, technical specs) and knows how to defend their architectural choices before a demanding technical team.
Stack and skills:
→ Clean Architecture + DDD
→ Flutter, Firebase, BLoC / Riverpod
→ Tech Lead: architectural decisions, coordination, mentoring, code review
→ Agentic Programming: Claude agents with tool use, MCP, and multi-step orchestration
→ Polished UX/UI
My way of working: I intervene upstream on architecture, I challenge specs when necessary, and I document what I deliver so that your teams can take over without hassle.
