What I'm looking for

I seek a collaborative, agile team role where I can build and optimize backend APIs and full-stack systems, grow technically, and contribute to high-impact projects.

I am a bilingual software developer with 8+ years focused on .NET backend development and full-stack work with Angular. I deliver clear, maintainable code across energy, airline, telecommunications, education, and construction sectors, and have driven refactors, performance improvements, and AI-assisted development to accelerate delivery.

I have experience building REST APIs, gRPC services, relational database solutions, and automated testing. I collaborate in agile teams, participate in code reviews, led the first RPA implementation at a site, and was recognized as Best Developer of the Year in 2019.
