Juste Tools is where I make the Unity tools I always wished existed: clean APIs, solid architecture, and docs that actually help.
Each one is shaped by real production experience at top mobile studios, and built to be a pleasure to use.

About Me
I'm Lucas Sarkadi, a Unity developer based in France. I started coding as a kid, tinkering for the joy of it, long before I knew it could be a career. That curiosity eventually led me through an engineering school and a game development program, then into the industry, where I spent years building in-house tools and SDKs at studios like Voodoo and Homa, two of the biggest names in casual gaming.
Along the way I kept coming back to the same thing: I love making tools. There's something deeply satisfying about solving a problem once, cleanly, so that no one ever has to fight it again. That's what Juste Tools is about.
Outside of work you'll usually find me at a game jam, behind a drum kit, or lost in some sci-fi. I believe good tools, like good games, come from people who genuinely care, and I try to bring that care to everything I publish here.
AI Usage
I use Claude Code as an AI assistant throughout development. All code and documentation is either written by me and reviewed by Claude, or drafted by Claude and reviewed and validated by me before it ships.
The public APIs are human-made: designing a clean, intentional API requires judgment that AI isn't quite there for yet. Everything else, from implementation details to documentation phrasing, is a collaborative back-and-forth where I stay in the loop at every step.
I believe in being transparent about this. AI doesn't replace the craft; it helps move faster without cutting corners.
