Freelancer profile translated to English.
Back to original languageAbout Norbert
I love creating software that users enjoy using! I offer my clients: IT Consulting and Senior Development of e.g. Web/Mobile Apps, ETL Pipelines, Migration of Legacy Apps
My working method is structured, goal-oriented and characterized by a sense of duty. I am convinced of Test Driven Development and the importance of documenting my work comprehensibly.
Although I am used to proactively and independently fulfilling the tasks entrusted to me through my self-employment, it has become apparent that I often act as an integrating figure within teams. Among my colleagues, I am known as a very approachable and helpful, conscientious and meticulous worker.
The things I tackle ultimately work. Especially to the satisfaction of my clients and also of those who have to maintain the code in the long term. Over-engineering is not only pointless but also expensive, and the simplest solution is not always the best - as simple as possible, as complicated as necessary.
