About Me

Welcome to my webpage! Here's a glimpse into my career path — in my current role I've discovered a growing excitement for Data Engineering and Warehousing. This complements my academic background in Data Science and my ongoing doctoral research in Information Systems at the University of Koblenz, offering me a comprehensive big picture of the field.

Being active in both enterprise engineering and research allows me to understand the interconnectedness and vital role they play in each other's success. It's been an enlightening journey, where I've also mastered the Data Vault technique, earning my practitioner certification. This site displays my ongoing journey: a balance between the fast-moving field of Artificial Intelligence & Data Science and the robust, scalable framework of Enterprise Data Warehousing.

Professional Experience

AI/Data Engineer at GIZ in Bonn

2024 – Present

I work with Azure AI Foundry, deploying and managing agents and prompt flows to automate enterprise workflows. I build production data pipelines from ingestion (web scrapers, connectors) through transformation using Medallion architecture and Data Vault principles for historization, all powered by PySpark and Delta Lake tables in Microsoft Fabric. I develop automated evaluation pipelines and judge-AIs for evaluating model performance, conduct performance benchmarking and optimization of AI models in production, and build advanced reporting and data models to bridge analytics and engineering capabilities.

Hospitation in Lima, Peru

2025

During my three-month on-site assignment in Lima, I supported international cooperation projects by working with local teams on data initiatives. I built POCs and pilots with local partners, including agentic AI systems that can autonomously access various information flows. I contributed to reporting, process automation, and intercultural knowledge exchange, gaining valuable exposure to development cooperation in practice.

Junior Data Specialist at GIZ in Bonn

2022 – 2023

In my role as a Junior Data Specialist, I implemented and programmed in Azure Synapse while innovating with machine learning to improve data efficiency. I brought together the worlds of Data Science and Data Engineering, refining our approach to data and ensuring it was not only managed but also intelligently transformed into valuable insights. By integrating machine learning with scalable Data Vault techniques, I advanced our systems toward smart automation and predictive capabilities, making our data strategies both time-efficient and future-ready.

Dual Student at GIZ in Bonn and Frankfurt am Main

2019 – 2022

My dual studies at GIZ combined academic learning with substantial professional experience across multiple departments. I applied university principles in real-world projects, contributed to the workers' council, and developed a strong foundation in digital operations and international project management, gaining hands-on experience in development cooperation.

Projects

A selection of practical projects and research ventures across web engineering, natural language processing, and IoT analytics.

The Portfolio Website Challenge: A journey into web development

Curious about new technologies, I took on a two-day challenge to build this particular portfolio website. It was a practical jump into web development — a field new to me — with the aim of creating a space that represented my professional journey. I started with the basics of HTML, CSS, and JavaScript. Then I moved on to deployment, where Render was suitable for clean and reliable deployment. Now all I needed was a domain to make myself visible in Google searches. I configured my domain via IONOS. The result was a clean, efficient platform to bring this site to life. This project demonstrates my adaptability and willingness to learn directly by building.

Exploring Genre and Success Classification through Song Lyrics using DistilBERT: A Fun NLP Venture

The Song Analysis App was a key university project where we ventured into the fusion of artificial intelligence and music. Harnessing the power of Large Language Models (LLMs) such as BERT, our team developed a Streamlit-based dashboard capable of deciphering the complexities of song lyrics. In a project with fellow data science students, we developed a solution that not only categorises song genres, but also predicts their release years and measures their popularity. More than an academic exercise, this project was an exploratory odyssey into uncovering patterns with machine learning precision.

Data Insights in IoT for Pets

In this capstone project, I delved deep into machine learning to analyze IoT data from dog trackers. Working with two other students over three months, we aimed to understand pet owner behaviors and enhance device functionality. Our close collaboration with the business taught us about managing requirements and the importance of continuous improvement. We tackled challenges in data processing and interpretation, applying complex ML algorithms for valuable insights.
