Project Manager and Full-Stack Developer

Lese-Drache is a reading training app for kids, founded and initiated by me to support young learners in improving their reading skills through interactive content.

Position

Position

I am a pragmatic Software Engineer who adapts quickly to the lifecycle stage of a product, the team's composition and skills, available resources, and the state of the codebase. I thrive on solving challenges within real-world constraints, ensuring the most efficient path forward. I'm a straightforward and efficient communicator, always aiming to keep discussions clear and productive.

I believe in the "work backwards" approach, starting with the customer's needs and then determining the most effective way to build the solution. Whether dealing with legacy systems or limited resources, I focus on delivering value by adapting my approach to the specific situation at hand.

I also believe that is a true . By sharing knowledge and supporting others in their growth, I help elevate the overall capability of the team, creating a collaborative environment that maximizes both individual and collective productivity.
