## What I Do

AI integration & AI-assisted development

Since 2025 I've designed, built and launched multiple products solo — LLM features on OpenRouter, daily work with Claude Code, Codex, Cursor & co. I help teams put AI to productive use.

Frontend modernization

Migrated 250k lines from RequireJS to Vite — as lead. If your frontend is stuck on a legacy stack, that's exactly my terrain.

End-to-end ownership

Concept → development → deployment → operations. PWAs, distributed backends (PostgreSQL, Kafka, Elasticsearch), CI/CD, Playwright/Vitest, monitoring. Software that runs — not just code.

Energy & IoT

Hands-on experience installing PV, heat pumps and battery storage — integrated with MQTT, Node-RED, ESP32, Grafana. A rare combination of energy tech and software.

→ renewable energy journey
