Open to contract, full-time remote, advisory

Software engineer with 6+ years of enterprise experience at BNP Paribas and Credit Suisse, currently AI Champion at Synergy Codes. I build production systems with AI inside — RAG, agents, evaluation pipelines — with a focus on reliability and predictable cost.

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.

Open to a range of roles — AI is my edge, not my whole scope.
