Luka Breitig

Luka Breitig is a technical product builder, AI developer, and solutions architect based in Germany. He builds complete products from concept to production — AI systems, real-time web applications, and workflow automation tools for teams that need them to actually work.

With a background that bridges psychology, management, and software engineering, Luka takes a human-centred approach to building production systems. He holds a Psychology BSc and a Management MA, and is a triple scholarship recipient — including the Stiftung der Deutschen Wirtschaft (SDW) — placing in the top 2% nationally.

Before focusing on software development full-time, Luka spent six years as Co-Founder & CTO of the marketing agency The Happy Beavers, achieving an 80% automation rate across business processes. This experience gave him deep insight into where automation creates real leverage and where human judgement remains irreplaceable.

Today, Luka specialises 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 projects include:

• Tymeslot — self-hostable scheduling platform with real-time calendar sync, embeddable booking widgets, and n8n integration
• Transvexis — multilingual translation platform serving 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 covers practical patterns and insights from building AI products and integrating LLMs into real applications — all from direct experience building and operating these systems.
