At DB Systel GmbH, I work on the frontend and backend of a web application that automates certificate delivery. Using Python, AWS Lambda, CloudFormation, and CI/CD, the automation saves several hours of manual work each week.
I developed an internal search application covering company websites, SharePoint, and other sources. I used feedback and analytics to guide further development with TypeScript, Vue.js, Kotlin, Spring Boot, and Solr.
Earlier at DB Systel GmbH, I built Spark and PySpark pipelines that processed approximately 10–50 GB of telecommunications data per day, making the data available for analysis for the first time. During my dual study programme, I also developed Spring REST APIs, Angular frontends, and Neo4j-based systems, and built the backend and admin frontend for a customer-service voice assistant prototype.
For my master’s thesis with Dianovi, a Darmstadt startup, I implemented a medical RAG system using Python and LLMs and compared plain embeddings with RAPTOR. Independently, I’ve built and maintained multiple projects, including an app with 100,000+ registered users.
