About

I'm a fullstack web developer based in Germany, specializing in building modern, responsive web applications with a focus on user experience and performance.

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.

Recently, I've been focused on developing AI-powered applications that automate complex workflows and enhance productivity. These systems either operate autonomously to dramatically improve efficiency or work alongside users to handle routine tasks, allowing teams to focus on creative and strategic work that requires human insight.

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").

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.
