Document Intelligence & OCR Engineering
- End-to-end document extraction pipelines covering OCR engineering, layout-aware extraction, and document classification. Adaptation of transformer-based models for client-specific document types, including preprocessing techniques for low-contrast and poorly scanned pages.
Machine Learning & Deep Learning
- Development of ML and deep learning models for structural element detection in scanned documents, production classifiers using hybrid CNN-plus-keyword-matching approaches, and fine-tuning of models using LoRA and parameter-efficient methods (PEFT).
Reinforcement Learning & LLM Post-Training
- Experimentation with RLHF failure modes including entropy collapse, reward hacking, and length hacking in GRPO fine-tuning of small language models. Development of PPO and DQN agents for various environments.
Transformer Models & NLP
- Application of transformer-based architectures for document understanding, text extraction, and language model adaptation across multiple domains.
Computer Vision
- Building and deploying computer vision models for document layout analysis, structural element localization, and image-based classification tasks.
Data Analysis & Visualization
- Exploratory data analysis using Python libraries such as pandas, NumPy, and dask. Data visualization with geopandas, pydeck, folium, seaborn, and matplotlib.
SAP & Automation
- Automated invoice-to-SAP reconciliation, Excel automation for production line reporting, and automated query routing systems with confidence-threshold-based human escalation.
CAD & Mechanical Simulation
- Hands-on design and simulation experience in Creo, CATIA V5, and ANSYS. Generation of CAD models, STEP geometry processing, automatic 2D drawing generation, and DFM/FMEA analysis.
Scientific Computing & FEA
- Development of an in-house TET4/TET10 FEA solver validated against CalculiX with 0.00% deviation at 119k nodes. Matlab-based dome profile optimization and thickness calculation using netting analysis and optimal methods.
Web Scraping & API Integration
- Web scraping for data acquisition and extraction of data from APIs such as Twitter and IMDb for analytical purposes.

Projekthistorie
Exploratory data analysis of different domain datasets in Python using pandas, NumPy, and dask for data wrangling. Data visualization using geopandas, pydeck, folium, seaborn, and matplotlib. Extracted data from Twitter and IMDb APIs and performed web scraping for data analysis.
Master Thesis on dome shape optimization of composite pressure vessel for storing hydrogen. Developed Matlab code and spreadsheets for analyzing and optimizing dome profile and thickness calculation using netting analysis and optimal methods. Generated CAD models, calculated fiber orientation, layer sequence, hoop and axial stress, and radial displacement along the composite pressure vessel.
Internship focused on spray analysis on injection systems. Developed a new GUI in LabVIEW for operating the bi-slide electric motor at spray analysis test bench. Designed and developed flexible injection adaptation for spray analysis at the optical test bench. Performed mass measurements for hydraulic characterization of fluids and microscope imaging of SCR injectors, GDI injectors, and O-rings.
