Luka Sandvoss — Full-Stack Developer & UX/UI Designer

// about

The thinking is the work.

I'm a full-stack developer and UX/UI designer based in Germany. I design and build web & mobile products, including custom APIs and workflow automation. Before I write a line of code, I work to understand your brand, your users, and what you actually need. Most projects fail not because of bad code — but because of bad decisions made before the code started. I fix that.

~/luka/how-i-work.md

// How I actually work

I start with questions, not tools.
What is this really for? Who uses it?
What do they need to believe before
they take any action?

Once the thinking is solid, the
code becomes obvious. The best
architectures match the problem
exactly — no more, no less.

I use AI to move faster.
I own every decision I ship.
