About

I'm a Mechanical Engineer based in Berlin, specializing in HVAC system design and BIM engineering. With experience spanning technical planning at UNDKRAUSS AG, BIM coordination at Sasez GmbH, and undergraduate research at McGill University's Centre for Intelligent Machines, I bridge the gap between traditional engineering and modern digital tools. On the side, I build iOS apps and web applications with Swift, React, and Next.js.
