About

I am a skilled senior/lead full-stack .NET developer with 19+ years of experience across the SDLC, including 4+ years as a team lead and mentor. I’ve built micro-service architectures, cloud-native and event-driven solutions on Azure and AWS, and I excel at extracting hidden requirements from stakeholders, communicating clearly, and delivering high-quality software. I regularly collaborate with cross-functional teams, document decisions, and enjoy guiding others while leveraging AI tools like Copilot to boost productivity.

I am a self-starter who thrives in fast‑moving environments, values code reviews and best practices, and am passionate about creating reliable, scalable systems that meet real business needs. I pride myself on clean architecture, mentoring teammates, and turning complex problems into practical technical solutions.
