About
Luka Breitig created and maintains Tymeslot. He built the scheduling engine, the CalDAV sync layer, the Phoenix LiveView booking UI, and the embeddable widget infrastructure: the systems documented in these pages. He works as a software engineer and AI developer, based in Warsaw, Poland.
His technical focus sits across two areas:
- Elixir and Phoenix LiveView: production backend services, real-time interfaces, and self-hostable platform architecture
- AI-assisted development: LLM integration, RAG pipelines, and agentic workflows built with Claude and OpenAI
His other live projects include In A Nutshell (AI semantic search for video content with timestamp citations) and Transvexis (multilingual translation serving clients in 39+ languages).
Alongside building, Luka trains engineering teams on AI-assisted software development: agentic workflows, AI code review, and navigating unfamiliar codebases with tools like Claude Code and Cursor. He delivers workshops for organisations including NobleProg and Cegos Integrata, and has spoken at international developer conferences on AI integration and production patterns.
