About

Professional summary

I am a senior full stack developer with more than 20 years of experience building enterprise web applications and technical solutions.

My core background is in .NET, C#, ASP.NET, and .NET Core, with strong experience across backend architecture, REST APIs, and scalable application design.

I also work confidently on the frontend with Angular and React, and I have contributed to user interfaces, interactive modules, and modern web experiences in complex business systems.

Throughout my career, I have worked with cloud platforms, microservices, Docker, Kubernetes, CI/CD pipelines, and Agile delivery practices, helping teams build and release reliable software.

I have led technical efforts, supported development teams, and contributed to architecture decisions, code quality, onboarding, and delivery consistency across multiple projects.

I am comfortable working across the full stack, collaborating with cross-functional teams, and solving problems in environments that require both technical depth and practical execution.

I am open to opportunities where I can contribute as a senior engineer or technical lead, especially in projects that value clean architecture, modern development practices, and long-term product quality.
