I build applications that work reliably when it matters - not just in presentations.
I build robust applications from concept to deployment, focusing on AI-enhanced features that solve real business problems.
I provide strategic guidance and hands-on training to help your team successfully adopt AI and modern development practices.
How I help teams build AI systems
From Business Problem to Production System
I bridge strategy and execution. My psychology and management background helps me understand business problems quickly, then translate them into technical architecture. I build production-grade systems using Elixir/Phoenix and Python that scale and integrate with your infrastructure.
6 Years as CTO, 80% Automation Rate
I spent 6 years as CTO automating a marketing agency from the ground up. The key insight: understanding workflows before choosing tools. I help identify what's worth automating, then build it using n8n, Zapier, or custom code so your team can maintain it.

Hands-On Workshops • International Conference Speaker
I teach technical teams to integrate AI into production systems through hands-on workshops. We build real features together while I explain the reasoning behind architectural decisions, so your team can ship AI independently.

Featured Work
Production systems I've built and real-world solutions I've architected
I was tired of seeing businesses pay high monthly fees for basic scheduling tools while losing control over their data. So I built an open-source alternative to Calendly that anyone can self-host. The real challenge wasn't just the interface, but ensuring that double-bookings never happen across different calendar providers. I chose Elixir and Phoenix LiveView because they allow me to handle complex, real-time updates with the kind of reliability that mission-critical scheduling requires.
I noticed that most AI translation tools tend to strip away the personality of the original writing, turning everything into dry corporate speak. I wanted to fix this, so I developed a system that treats translation as an act of style preservation rather than just swapping words. By building multi-stage processing pipelines, I managed to keep the author's unique voice and rhythm intact across more than 39 languages, making sure the cultural context isn't lost in the process.
I often found myself scrubbing through long YouTube videos just to find a single piece of information, which felt like a massive waste of time. Since ChatGPT can't process an entire hour-long transcript at once without losing the thread of the argument, I built a system that intelligently breaks videos down into meaningful topics. This allows you to ask questions and get answers with exact timestamps, helping you find what you need without the frustration of manual searching.
I'm Luka Breitig, an AI Developer & Solutions Architect who understands that the hardest part of AI isn't the model—it's the implementation. As a former German Foundation of Business scholar (top 2%) with a dual background in Management and Psychology, I bring a unique perspective to technical challenges. I've spent years building production systems where reliability isn't optional, specializing in Elixir, Phoenix, and Python. My mission is to bridge the gap between technical complexity and business value, creating AI solutions that don't just wow in demos, but deliver measurable results and natural user adoption.
"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.
