Hi, I’m Sebastian. What started as a fascination for technology on the rails led me to software development. At 40, I hit the reset button – out of the driver's cab, into the code. After retraining as an application developer and gaining 1.5 years of hands-on experience in a development team, I now build web applications remotely – curious, focused, and ready for the next step

Frontend or backend? What matters to me is that it works – clean, stable, understandable. PHP, Python, JavaScript, CSS, frameworks, APIs, databases, and containerized environments are all part of my toolkit. The foundation was built during my training, refined through real-world projects – and the learning never stops.
