Full-Stack Engineer · Founder · Germany

I build scalable web apps with love.

Passionate about SaaS products, modern web architecture and exceptional developer experience — owning products from the first idea through to running them in production.

Nils Freund
About

Hi, I'm Nils.

A developer passionate about crafting digital experiences that make an impact.

My focus lies at the intersection of design and engineering, where I build performant, accessible applications. I believe in writing clean, maintainable code and shipping software I'm proud of.

What truly excites me is taking ownership of a product from start to finish - from the first spark of an idea through architecture, implementation, and delivery. I thrive when I am able to shape the entire process: understanding user needs, making design decisions and delivering something complete.

As a huge open-source enthusiast, I'm slightly obsessed with self-hosting everything I can. There's something deeply satisfying about setting up my own infrastructure and knowing exactly how everything works under the hood.

When I'm not coding, I like to get out into nature, be creative in the kitchen, keep active with sports and hone my skills at the pool table.
