What I'm looking for

I seek senior technical leadership roles where I can design scalable .NET systems, lead engineering teams, improve CI/CD and observability, and drive product growth in a collaborative, outcome‑focused environment.

I am an experienced CTO, software architect, and senior full‑stack developer with a track record of delivering scalable .NET platforms across retail execution, travel tech, and event management.

I have led teams to build high‑performance microservices on cloud infrastructure, optimized complex data pipelines with ClickHouse, and implemented identity management with OKTA while improving CI/CD and observability.

My accomplishments include modernizing large .NET Core systems, architecting secure authorization, shipping production‑grade services that increased deployment frequency and reduced incidents, and co‑founding and scaling a commercial event management product.
