About Jakob

I develop software solutions that actually work:

from AI-powered tools to complete SaaS products.

As a specialist in application development with over 7 years of experience, I have moved from classic web development to AI integration and product development.

I have built RAG-based AI systems for enterprise use, scaled SaaS platforms from 0 to paying users, and today I lead a cross-functional team as an AI Champion at one of Germany's largest digital companies.

What I help with:
• AI integration into existing products (RAG, LLM workflows, chatbots)
• SaaS development (Full-Stack, React, Node.js, APIs)
• WordPress / WooCommerce for complex projects
• Automation & technical process optimization

I work remotely, deliver cleanly documented code, and think in products, not just features.
