Automate Business Processes

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.

Why I Deliver Results

Strategic depth meets technical precision

I Can Think Strategically

Can he understand my business problem?

Psychology BSc
I studied how people think, how organizations function, and how to analyze complex systems before I wrote my first line of code. This background helps me understand what your users actually need, not just what they say they want.
Management MA
When you explain your business problem, I understand your metrics, how your teams work together, and how technology can enable strategic goals. I can translate between boardroom and codebase.

Can he handle complexity?

Top 2% Scholar
I formulated and investigated complex research questions that required connecting psychology, systems theory, and human behavior. Selected as top 2% scholar by the German Foundation of Business, I learned to dive deep into new domains fast.
CTO for 6 years
I took operations from manual to 80% automated, led teams, and made architectural decisions that scaled with the business. I lived with the consequences of my technical choices for years—I know what breaks at scale.

Can my team learn from him?

Taught It
I've spoken at international conferences teaching developers how to integrate AI into their systems. I break down complex technical concepts so teams can understand not just the 'how' but the 'why' behind architectural decisions. Your team will learn, not just implement.

I Can Execute

Can he actually build production systems?

Built It
I've shipped several production-ready systems: a specialized translation engine, an AI-powered video analysis platform, an open-source scheduling system, and complex automation pipelines for client projects. All are currently running in production.
Scaled It
As CTO, I took business operations from manual to 80% automated—not as proof-of-concept, but as daily-use systems the team could maintain in production. Six years at Happy Beavers, I built infrastructure that scaled with revenue growth.

Does he know my tech?

7+ Years Production Code
I write production code in Elixir, Phoenix LiveView, Python, and modern JavaScript. I work with relational and vector databases, API integration, and cloud infrastructure. I've debugged concurrency issues at 3am and optimized database queries that were killing servers.
Built Complex Systems
I developed a custom machine translation engine supporting 30+ languages, architected to outperform general tools like DeepL by leveraging domain-specific terminology. This is production-grade AI designed for enterprise requirements.

Can I trust the quality?

Taught It
I've trained technical teams through hands-on workshops where we build real features together, not toy examples. I show them the gotchas, the production patterns, and the debugging approaches that actually work. Teams walk away shipping, not just learning.

Latest Project

Tymeslot

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 used Elixir's OTP to prevent real-time conflicts, ensuring that race conditions are eliminated even when two people try to book the same slot at once.
  • I implemented distributed state management with Phoenix PubSub so that booking states stay synchronized across servers without hitting database bottlenecks.
  • I designed a fault-tolerant architecture that allows for graceful degradation, meaning a Google Calendar outage won't bring down the whole system.

NLP & Translation

Transvexis

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.

In A Nutshell

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.

Frequently Asked Questions

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 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.
