Software engineer with 6+ years of enterprise experience at BNP Paribas and Credit Suisse, currently AI Champion at Synergy Codes. I build production systems that pair human judgement with AI — RAG, agents, evaluation pipelines — rather than demos that fall over on the first real user.

My stack spans .NET, TypeScript, Angular, Vue, React and the modern AI toolchain (OpenAI, Anthropic, Google, local models). I move between architect, tech lead and hands-on engineer depending on what the project needs.

Looking for roles where AI is part of the product, not a slide in the deck.
