[ 01 ] About
Technical ownership, back to front.
Over my career I've taken on increasing autonomy: I've been the lead front-end developer on a product, made architecture decisions, and run releases and deliveries. At one project stage I was the only developer, answering for everything from database to deploy.
On the back end, I build REST APIs in Spring Boot with tests from the start (TDD) and clean code. I have also set up CI/CD pipelines and used Docker and AWS in deliveries.
