About Ralf

Freelancer through my sole proprietorship extomics.com

I am a Senior Full-Stack Engineer (Angular • ASP.NET Core • Python + FastAPI) with a strong focus on modern, preferably AI-supported software development and reliable feature delivery in agile product teams (Scrum). I work with tools like Cursor, GitHub Copilot, and LLM-based code analysis to make development more efficient, consistent, and high-quality.

In addition to classic full-stack development, I can increasingly integrate GenAI/LLM components into internal workflows and product processes – e.g., with LangChain, FastAPI, vector search, and RAG concepts. My goal is to use AI not as a trend, but as a practical tool for better architecture, faster implementation, and tangible added value in the product.

With over 12 years of professional experience (FinTech, Energy, E-commerce), I was most recently the most technically experienced developer on the team. I make architectural decisions, define standards, enable other developers to work productively, and ensure clear, sustainable technical solutions. My working style is collaborative, transparent, and strongly focused on business value and feature quality.

Through my academic background in Bioinformatics and Biochemistry, I bring an analytical, precise, and interdisciplinary mindset that is particularly valuable in data-driven and AI-related topics.

I feel most comfortable in modern agile, cross-functional teams and support them not only with code but also with technical leadership, clear communication, and modern engineering practices.
