Hi, I’m Coulston Luteya.

I am a software engineer who finishes what he starts. I design, build and ship web and mobile apps, from the first sketch to the store listing.

On the front end, I make interfaces that respond, interact and don’t throw tantrums. On the back end, I handle the data and keep everything running behind the scenes.

The design gets the same care: clean, clear and just the right amount of clever. Most of my work is written in Flutter, React Native, TypeScript and PHP.

“Users shouldn’t need a manual.”

Have a project in mind?
