// About
Designer, developer, shipper.
I'm Serhii Hryn — an independent developer building the apps and tools I want to exist, and finishing them properly.
Since 2024 I've shipped 3 mobile apps — Brainee, Walletee, and Habitee — to the App Store and Google Play, plus premium game templates to the Unity Asset Store. Every one of them started as something I needed myself.
Working solo means the same person who sketches the interface also writes the data layer, profiles the frame times, takes the store screenshots, and answers the reviews. It's slower than a team — and it's why the details line up.
Apps are built with React Native, Expo, and TypeScript. Game tools are built with Unity and C#. This site runs on Next.js. The common thread: small, fast, carefully finished software.

// How I work
01
Ship end-to-end
Concept, design, code, store listing, support — one pair of hands carries each project the whole way. Nothing gets lost in a handoff.
02
Performance is a feature
Software should feel instant on the hardware people actually own — mid-range phones on flaky connections, not just demo devices.
03
Tools should feel premium
Whether it's an app screen or a Unity editor window, the details matter: typography, motion, empty states, error paths.
