MateuszKruhlik/README.md

Hi, I'm Mateusz 👋

I design the apps behind connected devices — from BLE pairing flows to the design system.

Product designer by profession. After hours I build the tools I wish existed, print their enclosures, and photograph the process.

Things I've shipped

🎨 OKLCH Palette Generator — Figma plugin for perceptually uniform color systems: 8 roles × 11 shades, live WCAG/APCA contrast badges, Figma Variables with light/dark modes. Free & open source → source code

💡 MoonsideBar — native macOS menu-bar app that turns a desk lamp into a physical status light for AI coding agents. SwiftUI + CoreBluetooth, reverse-engineered BLE protocol.

🧠 Omni Brain — local-first second brain as a git repo: specialized AI experts with clean contracts + RAG over books and video courses. Works in any AI IDE.

🔊 Rabi Sound — local-first browser generator for clean, royalty-free UI sound effects. Compose tone + noise layers, export production-ready WAV files and sound packs. Free & open source, built on Cuelume.

Beyond the screen

🖨️ I design and 3D-print enclosures (Bambu Lab X1C, ASA) — a product doesn't stop at the PCB. 📷 Ricoh GR in my pocket, film scans in the archive.

Rabituza Studio — product design for connected hardware. Website coming soon. Figma Community
