// Indie developer — mobile apps & Unity assets
Apps people keep.
Tools developers build on.
I'm Serhii Hryn — an independent developer who designs, builds, and ships the whole thing: three mobile apps on the App Store and Google Play, and premium game-dev toolkits on the Unity Asset Store.

One person, end to end.
I'm Serhii Hryn. Every project here is designed, built, and shipped by me — from the first sketch to the store listing. No handoffs: the same person who draws the interface also profiles the frame times.
Apps are built with React Native, Expo, and TypeScript; game tools with Unity and C#. The common thread is craft — small, fast, carefully finished software.
