Senior full-stack .NET developer with 6+ years of experience building scalable enterprise applications at Credit Suisse, BNP Paribas and Synergy Codes. C#, .NET, Web APIs and modern front-end work.

I work across software architecture, technical leadership and AI-assisted development. As AI Champion at Synergy Codes I drive practical AI adoption — evaluating tools and use cases, and setting the engineering practices that keep them useful in production.

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