What I'm looking for

I’m looking to own backend services end-to-end—design through deployment—building REST APIs and microservices on .NET and Azure for high-availability, regulated systems, collaborating closely with clients and mentoring engineers.

I’m a Senior .NET Developer with 8+ years designing and shipping backend systems across FinTech, healthcare, and government platforms. I architected and delivered REST APIs and microservices on .NET Core/.NET 8, supporting national-scale digital banking and public-sector applications with teams of up to 55 engineers.

I integrate payment gateways, authentication services, and third-party APIs for regulated, high-availability systems. I’m Microsoft Certified in Azure (Fundamentals & Developer Associate), and I’m comfortable owning a service from design through deployment while mentoring engineers along the way.

I’ve improved performance through query optimization, caching strategy, and refactoring, and I build reliability with unit testing. I’ve also collaborated remotely—delivering production code for a Czech engineering team for over two years—while working directly with clients and stakeholders to turn requirements into technical solutions.
