AI workflows.
Useful software.
Playable worlds.
I’m Serhii, a software engineer with 7+ years of experience. I build AI-assisted products, full-stack systems and interactive experiences. Here is selected work from my independent projects.

Worlds you can play.
Games, tools
and new ways to interact.
Zerno is where I’m developing a practice around mobile game adaptation. One current project is a playable Android prototype of the open-source factory game shapez.
My focus: the touch editor, responsive layouts, Android integration and a repeatable feedback loop.

Primordial.
Life in a drop.
Swim, feed and evolve in a microscopic world. Procedural creatures, physical encounters and an organism editor.

Frontend roots.
Hands-on engineering.
My foundation is Angular and TypeScript. My work now spans AI-assisted features, backend services, developer tooling and performance, alongside the game projects collected here.
I work from playable prototypes, observe where the interaction breaks, and iterate. My work spans interfaces, interactive systems and developer tools. This portfolio collects selected work and engineering notes as projects develop.
Zerno is the game adaptation part of that practice. Tanstafl brings my product and AI engineering work into the same portfolio.
