Summary

I am passionate about building and shipping software that matter to people. I have working on both front and backend throughout my entire career and also have plenty of experience when it comes to hyper scalers and cloud technology. Doing DevOps tasks is naturally party of my job, at least it is they way I am used to doing it. Also I usually actively engage in architecture and software design discussions. As I am a product person at heart I always try and consider the user’s perspective on anything I build. Automation is a mother key aspect of the job and I am driven by adding automation wherever it helps and makes sense. Also, I am always there for a chat about sports, coffee and good food.
