What I'm looking for

I am seeking senior engineering roles where I can design cloud-native systems, lead cross-functional teams, and drive scalable, secure SaaS platform delivery with strong emphasis on performance and CI/CD.

I am a Senior Full Stack Developer with 12+ years building large-scale, cloud-native SaaS platforms using C#, .NET Core, and modern JavaScript frameworks. I architect and ship microservices, optimize backend performance, and implement scalable CI/CD and cloud automation to deliver secure, high-availability systems.

My career highlights include architecting a microservices academic analytics system supporting 500K+ students, refactoring legacy .NET systems to .NET 6 to reduce deployment time and costs, building automation platforms that saved hundreds of IT hours, and mentoring engineers to improve code quality and test coverage.
