You get one person who handles requirements, designs the architecture, and writes the production code.
I build complete products from concept to production. My psychology and management background means I understand what needs to be built, then build it: AI systems, real-time applications, and workflow automation that scale.
Former CTO who automated 80% of agency operations over 6 years. I teach at international conferences and train teams to integrate AI into production systems through hands-on workshops where we build real features together.
How I help teams build AI systems
From Business Problem to Production System
My psychology and management background means I understand business problems without needing detailed specs; I figure out what should be built, then build it. Complete systems from concept to production: AI-powered applications, real-time collaboration features, and semantic search platforms. You point me at a problem, I own it end-to-end and ship it.
6 Years as CTO, 80% Automation Rate
Six years as CTO taught me the key insight: understand workflows before choosing tools. I audit your operations, identify what's worth automating (some manual work should stay manual), then implement using n8n, Zapier, or custom code. You get systems your team can maintain and scale as the business grows.

Hands-On Workshops • International Conference Speaker
My psychology background means I understand how people learn. I've taught at international conferences and trained technical teams through hands-on workshops where we build production features together. I explain the reasoning behind architectural decisions: the gotchas, production patterns, and debugging approaches that actually work. Your team walks away shipping AI features independently.

Featured Work
Complete systems shipped, from concept to production, serving real users
Open-source scheduling platform that businesses can self-host instead of paying recurring SaaS fees. The core challenge: ensuring zero double-bookings across different calendar providers (Google, Microsoft, CalDAV) while maintaining real-time updates. Built with Elixir and Phoenix LiveView to handle concurrent bookings with the reliability mission-critical scheduling demands. Production-ready system serving businesses who need calendar synchronization without vendor lock-in.
Specialized translation platform that preserves the author's voice and style across 39+ languages. Standard AI translation tools flatten personality into corporate speak; this system treats translation as style preservation. Multi-stage LLM pipelines with iterative refinement and context injection maintain terminology consistency and cultural nuance. Live and serving paying clients with 40-60% reduction in post-editing time compared to DeepL for domain-specific content.
AI-powered semantic search for long-form YouTube videos. Standard LLMs lose context when processing hour-long transcripts; this system intelligently segments videos into meaningful topics and builds a semantic index. Ask natural language questions, get answers with exact timestamp citations linking to the relevant moment. Eliminates manual scrubbing through long content to find specific information.
I'm Luka Breitig, a Technical Product Builder who bridges business strategy and technical execution. Dual background in Management and Psychology combined with self-taught development. I understand business problems without detailed specs, then build complete solutions that ship. I can talk to clients about requirements, make strategic technical decisions, then write the code. Three production systems live: specialized translation engine, AI-powered video analysis platform, and open-source scheduling system. All serving real users, generating measurable results.
"Your team won't use AI tools they don't trust. I build systems that integrate naturally into existing workflows - because I understand both the code and the people."

Most AI projects fail not because of the technology, but because of a lack of user adoption. My background in psychology and behavioral economics allows me to design AI systems with human-centric adoption baked in from day one. By understanding mental models and reducing friction, I build tools that teams actually want to use. Combined with full-stack development experience, this ensures your AI investment delivers both technical excellence and real-world results.
Partnering with a senior specialist ensures high-trust execution and direct access to expertise without the overhead of account managers or junior developers. I build systems your team can own, prioritizing clean architecture, thorough documentation, and seamless knowledge transfer. To ensure long-term stability, I work with clients to either train their internal teams or establish clear, sustainable maintenance agreements.
While off-the-shelf tools are great for general tasks, custom AI infrastructure is required for deep integration with your tech stack, proprietary data usage, and enforcing complex business rules. I build operational systems that automate multi-step workflows—like syncing CRM data, inventory checks, and proposal routing—creating a competitive advantage that a standard chatbot cannot provide.
I bridge the gap where most AI projects fail: the translation between business requirements and technical feasibility. My background as a German Foundation of Business scholar combined with hands-on engineering means I can architect systems that are both technically sound and economically sensible. This ensures your project is aligned with your CFO’s goals while remaining highly implementable for your engineers.
I define clear success metrics—such as cost reduction, time saved, or revenue impact—before writing a single line of code. By validating assumptions with small, early experiments, we avoid the trap of 'AI for AI's sake.' If a simpler automation or spreadsheet is the better solution, I’ll tell you. My focus is on solving your business problem efficiently, not on maximizing engagement hours.
The choice depends on your specific goals: n8n is ideal for rapid prototyping and validating workflow ideas with minimal investment, while custom code (Python, Elixir/Phoenix) is reserved for high-performance, complex logic, or production-grade reliability. I select the right tool for your current stage, ensuring you optimize for speed today without sacrificing scalability tomorrow.
I prioritize production-ready engineering over hype-driven demos. By working directly with your technical teams, I ensure every implementation is robust, maintainable, and survives the scrutiny of experienced developers. My reputation is built on delivering reproducible results that add long-term value, rather than one-off prototypes that collapse after the initial phase.
