1) AI Automation & Enterprise Delivery
- OfferGenerator (Flask → PowerPoint): implemented, tested, and deployed on a Domain Network; Manual offer creation was reduced from 4–5 hours to ~30 minutes (≈85–90%).
- Tender/Ausschreibung Generator (Flask → PowerPoint): designed for structured Generation of BA/MSc announcements; PDF Extraction, Template-driven PPTX Generation, and Azure/OpenAI-based Text Generation are integrated. Source content is derived from official PEM study pages (see: pem.rwth-aachen.de/go/id/fecr ). Automated export to Network Locations is supported.
- PowerPoint Add-in (C#, .NET Framework VSTO/COM): implemented, tested, and deployed on a Domain Network and developed as an internal Productivity Tool; GPT-enabled Text and Image Generation, Image Analysis, and different Text-to-Diagrams/Charts are provided; Production deployment for staff use has been established.
2) Enterprise AI (Privacy-First)
- On-Prem RAG (offline / privacy-first): Retrieval-Augmented Generation for internal Knowledge Workflows; Emphasis is placed on Governance, Operational Robustness, and Deployment constraints in Enterprise Environments.
3) Speech & Emotion Recognition (ASR/SER)
- AI-based Development: Speech & Emotion Recognition — Two Models: Separate Models for Automatic Speech Recognition (ASR) and Speech Emotion Recognition (SER) have been trained via wav2vec2 fine-tuning; Both audiofile-based and real-time inference are supported; Evaluation is performed via Word Error Rate (WER) and Unweighted Average Recall (UAR).
- HPC Training (RWTH High Performance Computing): Training and Inference workflows of the ASR/SER models are executed on RWTH HPC (SLURM) to accommodate large-scale datasets and controlled experiments.
4) Enterprise IT & System Integration (Avantis + BIC)
- Identity & Access: Active Directory and Group Policy Objects (GPO) are administered, including Groups/Permissions, Service Accounts, and File Server Access Control.
- Stability & Security: WSUS patching, Sophos Endpoint Security, CommVault Backups, Standardized Rollouts, Documentation, and Security Awareness/Testing are applied to support stable Operations.
- Site Operations: Multi-site Infrastructure work has been delivered at Avantis and the Battery Innovation Cluster (BIC) .
5) XR Learning Technologies (RWTH LearnTech)
- Project Context (04/2022–10/2023): contributions were delivered within the RWTH LearnTech environment (see LearnTech), including the Unity-based xTeach VR project (see xTeach VR).
- Spatial Audio Integration: Google Resonance Audio was integrated and parameterized for improved Realism of Distance and Room Perception in immersive Learning Environments (Unity-based audio Pipeline Design and Tuning).
- Learning Analytics Instrumentation: keyword recognition and interaction events were operationalized via xAPI; Statements were collected in a Learning Record Store (LRS) for subsequent Analysis.
- Analytics Visualization: Learning Analytics were processed and visualized through a React-based dashboard, enabling structured exploration of user behavior and interaction patterns.
- Research Stimuli: Experimental Stimuli were created and iteratively optimized to support controlled Studies (Audio Stimulus Engineering and Quality Assurance under Research Constraints).
