Senior backend engineer — .NET, distributed systems, AI-facing APIs
Senior backend engineer working mostly in .NET and C#, with a bias toward systems that stay understandable after the second year. I design and ship multi-tenant SaaS backends end to end: data model, API surface, auth, deployment. Lately I build interfaces meant for language models as well as for people — MCP servers and retrieval APIs over the same source of truth that renders the human-facing site.
