Luka Breitig

Luka Breitig is a technical product builder, AI developer, and solutions architect based in Germany. He created Tymeslot, an open-source meeting scheduling platform built with Elixir and Phoenix, designed for developers and teams who want full control over their scheduling infrastructure.

With a background that bridges psychology, management, and software engineering, Luka takes a human-centered approach to building production systems. He holds a Psychology BSc and a Management MA, and was recognized as a German Foundation of Business (SDW) Scholar — placing in the top 2% for research connecting psychology, systems theory, and organizational behavior.

Before focusing on software development full-time, Luka spent six years as a CTO managing operations and achieving an 80% automation rate across business processes. This experience gave him deep insight into where automation creates real leverage and where human judgment remains irreplaceable.

Today, Luka specializes in three intersecting areas:

• Custom AI infrastructure — large language models, RAG systems, and prompt engineering
• Backend development with Elixir and Python
• Workflow automation using tools like n8n

He has spoken at international conferences on AI integration and production patterns, and delivers custom training curricula for teams integrating AI into their existing workflows.

His notable open-source and client projects include:

• Tymeslot — self-hostable scheduling platform with real-time calendar sync, embeddable booking widgets, and n8n integration
• Transvexis — multilingual translation platform serving paying clients in over 39 languages
• In A Nutshell — AI semantic search for video content with timestamp citations

Luka believes that the best technical solutions are the ones teams actually adopt. His writing on the Tymeslot documentation covers practical, production-ready deployment patterns for Docker and Cloudron, automation integrations, and embedding strategies — all from direct experience building and operating these systems.
