About the studio

An independent studio, built on craft.

Rainpeak Signals is an independent software studio — a studio of one, founded and run by Zack Chiu, a veteran software engineer based in Vancouver, BC on Canada’s Pacific coast.

The name is rain + peak. It comes from two places that share the same weather: the mountains and rain of the Pacific Northwest, and the mountains and rain of Taiwan, where my roots are. Both taught me the same thing — that the clearest signal often arrives through the fog.

So that’s what the studio builds: software that cuts through the noise — apps and products that earn their place and actually get used. No team to hide behind — just one engineer who designs it, builds it, ships it, and stands behind it.

The throughline

Mountains and rain, in code.

Mountains and rain — in Vancouver and in Taiwan. The brand is a quiet reminder that the right signal can always find its way through.

How we work

Find the signal. Then ship it.

A small, honest process — the same four steps whether it's the studio's own product or yours.

  1. 01

    Find the signal

    Understand the real problem and the people behind it — cut the noise before writing a line of code.

  2. 02

    Design with taste

    Shape something clear, calm, and delightful — interface, words, and details that respect people's time.

  3. 03

    Build

    Engineer it properly — dependable, performant, and maintainable, with the rough edges sanded down.

  4. 04

    Ship & sustain

    Get it into people's hands, then keep it healthy — measured, supported, and improved over time.

Contract availability

Have a full-stack product to build? Let's talk.

The studio takes on a small number of full-stack projects — designed and built end to end, by the person who'll actually ship it. If that's what you need, you're in the right place.
