What I've built.

Training and finetuning language models to extract structured knowledge from SAP test documents. Goal: enriching the SAP Enterprise Knowledge Graph (EKG), SAP's next-generation platform for centralized enterprise knowledge.

International practice phase in Canada. Data engineering and pipeline development for training SAP Foundation Models, SAP's initiative for large-scale, enterprise-data-trained AI models. Focus: Cross-table schema integration.

Research project: Using knowledge graphs for automatic column mapping across heterogeneous table structures. Schema-agnostic data integration as a scalable prototype.

Analysis of internal business processes and development of AI-driven automation use cases in collaboration with project managers and delivery execution leads. Including demo development.

Implementation of new knowledge domains and automated pattern generation in the GCG Knowledge Graph (EKN). Then part of SAP Signavio Value Accelerator Delivery (VAD), responsible for SAP reference architecture and transformation content.

Formula Student team at DHBW Mannheim. In the Autonomous Systems Team: development of analysis tools and supervision of the sensor and perception module for the fully autonomous racing car.

A full-stack AI system, live in the Chrome Web Store: a browser extension that detects the political bias of articles, summarizes them and fact-checks claims. Powered by a FastAPI backend with GPT and a Next.js dashboard for API-key management and usage analytics.

A from-scratch reimplementation of the PRIMAL2 paper (RA-L 2021) for a seminar talk: a decentralized, communication-free policy for lifelong multi-agent path finding. Trained with A3C, imitation learning and a convention loss. Achieves 5–11× the throughput of greedy A*.

React / Next.js web app to simplify flight planning. One click: weather briefing, airfield charts, NOTAMs, navigation and weight calculations, all at a glance.

Self-hosted web app that scrapes the Bloomberg Billionaires Index on a schedule and stores historical snapshots of the top 500 in SQLite. The dashboard lets you track net-worth trajectories, run statistics and trend analysis, and export filtered data as CSV or JSON.

AI cooking assistant: snap a photo of your fridge, Gemini Vision recognizes the ingredients and generates matching recipes, weekly plans and shopping lists. With a cooking mode (text-to-speech) and a multilingual interface. Full-stack, as a PWA and Docker container.

Web app for creating QR codes (URL, WiFi, VCard and more). Modern React/TypeScript frontend with an Express backend, containerized for self-hosted deployment.

My first real website. Nothing special, but an important beginning. I still use it today to keep track of my groceries.

My very first contact with programming: a game project from 11th grade computer science class. Never fully finished, but the beginning of it all.
