Okke Harsta
Full Stack developer
I'm a experienced Full Stack software developer and IT security consultant. I strongly believe in lifelong learning and I take pride in my versatility.
Currently my favorite stack is a Java (Spring Boot) or Python (Django or Flask) backend with a React JS or Svelte frontend.
My main passion is building and shipping great software.
