About

I'm an AI developer based in Germany, researching and building the future of software. I strongly believe AI in software can go far beyond chatbots - and I'm creating systems that prove it by deeply integrating AI into software in innovative and meaningful ways.

My expertise lies in the Next.js ecosystem, where I leverage React, TypeScript, and modern frontend technologies to create scalable and maintainable applications. I combine technical proficiency with an eye for UI design to deliver solutions that are both functional and aesthetically pleasing.

My work includes projects like Sourcevise - an AI-powered B2B procurement platform that infuses AI throughout the supplier sourcing workflow, from intelligent matching across millions of data points to automated outreach and market analysis. I specialize in deeply integrated AI systems that fundamentally transform how software works, leveraging multi-agent architectures, RAG pipelines, and modern LLMs to create experiences that weren't possible before.

Fullstack Developer2022 - 2025

Core developer on Teampilot AI, a generative AI platform. Designed and implemented its core multi-agent system and the Perplexity.ai-like web connection feature (synthesizing web info via search APIs, Cheerio crawling, custom summarization). Integrated LLMs (OpenAI) and built RAG pipelines (Qdrant, OpenAI embeddings). Developed 5+ full-stack client apps (Next.js, tRPC, PostgreSQL) and collaborated directly with clients. Solely developed a data enrichment platform using Next.js (App Router, Server Components) & PostgreSQL; this platform leverages Teampilot AI's multi-agent capabilities to automate complex data enrichment tasks, effectively replacing manual processes previously handled by student workers ("Werkstudenten"). Features a user-friendly shadcn/ui interface. Also involved in client onboarding/support within small agile teams.

Fullstack Developer (Part-Time)2020 - 2022

Led the design, development, and deployment of Pegel-Dashboard (React, Node.js/Express), an internal platform managing a large-scale project digitizing physical water level records for German government agencies. Built a Node.js resource management system to optimize digitization by dynamically scaling Hetzner servers based on processing demands, preventing database overload and ensuring efficient resource utilization. Developed an interactive viewer (Next.js, tRPC) for overlaying digitized data onto original record images, enabling visual verification. Engineered its custom, high-performance Canvas rendering solution to handle large images and complex coordinate transformations (non-standard origins, aspect ratios). Collaborated with 3 developers on the core digitization, providing monitoring tools.
