❤️ I am a full-stack senior software engineer located in Cologne. Whilst living a great passion for frontend development, I really love to implement backends filling their counterpart with data and business processes.
Also, my ability to develop databases and the surrounding infrastructure make me feel like I have developed something complete when finishing a product.
In my free time, I fulfil my passion to coding, cars, music and video games.
I would describe myself as a team-player, being in love with hand-in-hand work. For example, developing against other developers' machines is really fun to me!
Today, I am working for Belonio as a full stack developer, who is providing a simple, secure and attractive software solution for providing employee benefits in terms of salary extras.
