About Me

Passionate about building scalable backend systems and modernizing legacy applications

πŸ‘¨β€πŸ’»

I am a Software Engineer with 6+ years of experience, mainly specialized in the .NET ecosystem (Framework, Core, and .NET 8). Strong background in backend development, legacy systems maintenance, and cloud modernization (AWS).

I have worked on building REST APIs with JWT authentication, refactoring legacy systems into modern architectures, restructuring corporate portals, and developing new scalable applications from scratch.

I also bring experience with NodeJS and Java 21, automated testing, CI/CD pipelines (Jenkins, Docker, Git), and monitoring (Datadog, Kibana, Grafana).
