Leo Hilsheimer
web development
I build websites and web-based tools — from one-pagers and portfolios to eCommerce platforms, internal systems, and mailing setups. I usually work solo, but I can bring in a designer or collaborate with your team. Feel free to share your ideas or needs with me.

About me
I started studying computer science at KIT Karlsruhe after high school, but left early to make music. I didn’t plan on returning to programming, but during the pandemic I ended up helping out in my family’s business and took over an aging PHP webshop. That experience was chaotic but formative — I learned the fundamentals of the web and how to manage infrastructure and developer tooling.
Since then, I’ve gradually moved from PHP into the JavaScript world, building websites for small companies, artists, and cultural organizations. In 2025, I teamed up with graphic designer Mona Mayer. Together, we offer websites that are not only functional and fast, but also visually thoughtful and sustainable to maintain.
