I started programming when I was 14, and I still enjoy it. I've been working as a software engineer for over 10 years. I've mostly used PHP, but throughout my career I've also worked in Javascript, Go, C# and Python. Additionally, I have some devops experience (docker containerization, configuring e2e and functional tests in GitLab CI, code quality tools).
