Summary
I am an experienced software engineer who has worked on many different types of software. I started as a research and development engineer with a master's degree in mechanical engineering, where I focused on engineering computer science. From my first role as an R&D engineer, where I programmed software for process control and analysis, I moved into data engineering in pharmaceutical production facilities. Now I have been working in web development for 7 years, mainly as a backend engineer, and I love constantly learning and tackling tough challenges.
