One person. Three ways to help.
I build products, help teams adopt AI workflows, and train developers. No agency overhead, no rotating developers — the same person who understands your problem is the one who builds the solution.
How I can help
Build, consult, or train — depending on what you need.
You need it built — not just spec'd.
Custom development
Complete products from concept to production. AI systems, real-time applications, and workflow automation — business problem first, then code.
Your team has AI tools but barely uses them.
Implementation consulting
Hands-on help adopting AI-assisted coding workflows that actually stick. Tool configuration, process consulting, and team enablement.
Your developers need to work with AI, not just hear about it.
AI & developer training
Practical AI coding workshops for developer teams. Claude Code, Cursor, GitHub Copilot — hands-on with real codebases, not slide decks. Online or on-site.

About me
Technical Product Builder
I'm Luka Breitig, a Technical Product Builder who bridges business strategy and technical execution. Dual background in Psychology and Management combined with hands-on engineering. I build complete products, help teams adopt AI workflows, and train developers — always starting with the business problem, not the tech stack. Three production systems live and serving real users.
"Technology only works when people trust it. Whether I'm building a product, consulting on adoption, or training a team — I start with understanding the people, not just the code."

Practical insights on AI technologies and real-world applications
Do LLMs really write better Elixir than Python?
A Tencent benchmark ranked Elixir #1 for LLM code generation. As an Elixir developer, I dug into the data — the truth is more nuanced than the headline, but the structural advantages are real.
From chatbot to agent: a step-by-step mental model for understanding agentic AI
Moving from conversational mimicry to autonomous execution: understand how agentic AI systems pursue complex goals, use tools, and adapt to changing environments through a continuous reasoning loop.

Common questions about AI consulting, development, and implementation
Most AI projects fail not because of the technology, but because of a lack of user adoption. My background in psychology and behavioural 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 learning on your project. I build systems your team can own, prioritising 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.
Off-the-shelf tools are great for general tasks, but 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 — syncing CRM data, running inventory checks, routing proposals for approval — creating a competitive advantage that a standard chatbot or API wrapper cannot provide.
I bridge the gap where most AI projects fail: the translation between business requirements and technical feasibility. My background as a 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 engineering team.
I define clear success metrics — 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 building AI for its own sake. If a simpler automation or even a spreadsheet solves the problem more efficiently, I will tell you. My focus is on solving your business problem, not on maximising billable hours.
The choice depends on your goals and timeline: n8n and Make are ideal for rapid prototyping and validating workflow ideas with minimal investment, while custom code in Python or Elixir/Phoenix is reserved for high-performance applications, complex business logic, or production-grade reliability requirements. I select the right tool for your current stage, ensuring you optimise for speed today without sacrificing scalability tomorrow.
I prioritise 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 excitement fades.
