About

I’m a Senior Full-Stack Developer with over 15 years of experience delivering robust web and desktop apps using Microsoft technologies (.NET, C#) and modern JavaScript frameworks (Angular, React). I excel at designing and deploying scalable microservices, REST APIs, and frontend solutions, and I thrive in Agile environments with a strong DevOps mindset.

What sets me apart are hands-on cloud deployment to Azure and AWS, strong Git-based version control and CI/CD discipline, leadership experience as Tech Lead and Scrum Master, cluster management with Rancher and Kubernetes, and robust observability using Grafana. I bring solid backend expertise (C#, .NET, Golang, SQL Server, Entity Framework) and a proven track record of tests (xUnit, NUnit, Moq, FakeItEasy).
