About

I'MYUVAL.

I build software that does routine work for small businesses.

I work with websites, automations, and custom tools for small businesses and independent professionals. My background in film composition and audio engineering shapes how I think about detail, rhythm, and how an interface feels.

Based in Lisbon

What I can build for you
Portrait of Yuval Lavi

01 / Background

From the studio to the screen.

Film composition and audio engineering taught me to listen closely, shape a story, and work within technical constraints. Those habits carry into development: understanding what matters, making deliberate choices, and paying attention to the details.

Today I build with TypeScript, Next.js and React, on PostgreSQL, Supabase or Firebase, and with Rust for developer tools. I bring that same attention to the way a website reads, a tool works, and an interface moves.
