01 — What we do
Four disciplines, one team
01
Mobile apps
iOS and Android — native, Flutter or Kotlin Multiplatform. Store launches, subscriptions, analytics, long-term support.
02
Desktop
macOS, Windows and Linux tools with native feel — menu bar utilities to full workstations.
03
Web & services
Next.js front-ends, Go and Node back-ends, PostgreSQL. Designed to be run, not just shipped.
04
Bots & automation
Telegram bots, LLM agents and pipelines that remove manual work from businesses.
