About

Full Stack Developer

I've been a developer for about 5 years, focused on robust web applications using ASP.NET Core on the backend and Angular on the frontend. I enjoy building products end to end, from the database to production deployment with containers and CI/CD pipelines.

I also work with mobile development using Flutter, creating cross-platform apps (Android/iOS) integrated with the company's systems.
