Reza Ilham wearing a party hat at a birthday table

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.
