I build web, mobile and desktop products end to end, from architecture and backend to polished interfaces and production operations. Lately with a strong focus on AI integrations and agent tooling. Based in Katowice, Poland, working remotely with teams anywhere.
Product-grade SaaS and internal tools with Laravel, PHP, PostgreSQL, React and TypeScript.
Cross-platform apps with React Native (Expo) and Tauri, sharing code with the web client.
MCP servers, LLM features and agent workflows that plug AI assistants into real products and data.
Architecture, testing (Pest, Playwright), CI, deployment and monitoring, so the product keeps running after launch.
A private planning system for your whole life. Designed and built solo across web, iOS, Android and desktop, with its own MCP server so AI assistants can plan your day.
Harness-agnostic agent orchestration policies, role contracts, model profiles and adapters.
Optional runtime extensions for AI coding harnesses.
