My Story & Philosophy


From the moment I finished my studies in Electrical Engineering and Information Technology at the University of Applied Sciences in Munich, I’ve been driven by a singular mission: to leverage technology in service of a sustainable future. With years of hands-on experience as a Renewable Energies Project Engineer (especially in the solar PV sector) in Germany and the rest of Europe, I witnessed firsthand the transformative power of green technology—and the urgent need for smarter digital tools to accelerate the energy transition. This inspired me to bridge the worlds of engineering and software development, mastering fullstack web technologies to build practical, impactful solutions.

I believe that every line of code can contribute to decarbonization, every app can empower smarter decisions, and every digital innovation can amplify the impact of renewable energy projects. Sustainability is not just a goal—it’s a philosophy that shapes how I design and develop software, ensuring it is intelligent, scalable, and purpose-driven.
