CatBoard
A native board for running Claude Code, Codex, and Antigravity in isolated Git worktrees. I design and build the product end to end.
Hi, I'm Reza Ilham.
I'm an iOS engineer at Aleph Labs, based in Indonesia. For more than 10 years I've worked on Apple-platform products across healthcare, telecommunications, and logistics, from early development through products used in the real world.
At Aleph Labs, I build iOS products as part of a team. Outside work, I take smaller ideas from design to code and release on my own. The latest is CatBoard, a native macOS app for running coding agents from one board.

About
I've spent more than a decade making iOS products in healthcare, telecommunications, and logistics. I care about clear interfaces, sensible defaults, accessibility, and code that remains understandable after launch.
Outside work, I make small apps, occasionally write, and release music as Erza.
