Summary

I'm Fabian, and a freelance React/Typescript fullstack developer. For over a decade I've been taking web apps from inception to launch and beyond. I coach teams in React and consult companies on crucial architecture questions.

I live by a "Zero-Bullshit Attitude." That means I make sure your project doesn't exceed the target, rather, the stakeholder requirements are addressed systematically. The final result is a product that is built to last, with quality that is secured for the long term.

I am proficient in cutting-edge technologies and also understand the fundamental principles of earlier days. In-depth knowledge, not just tutorials.

My belief: Clean and simple architecture always outshines excessive complexity. Without overengineering and costly missteps. Resulting in a more relaxed, forward-thinking, and transparent approach.
