Illia S. builds mobile apps with product thinking and AI tools.

Developer

My name is Illia S. I am from Ukraine, based in Poland, and FilinLab is my independent software studio for mobile app development.

I build with a mix of software development, product thinking, marketing experience, and modern AI coding tools. I use Codex and Claude Code to move from idea to working app faster, while keeping the product clear and maintainable.

Background

My first serious mobile app experience came from working with Ultiself, a company developing a habit tracker mobile app. There I learned how mobile products are prepared, published, and promoted on the App Store and Google Play.

That experience taught me the parts of app development that sit beyond writing code: store listings, support paths, user feedback, privacy expectations, product positioning, and long-term iteration.

Current Focus

I am now developing mobile applications independently through FilinLab. This site is the public place for app information, support contacts, privacy details, and company updates as products move toward release.
