👋 About Me

I'm a Master's student in Artificial Intelligence Engineering at the University of Passau, Germany, building AI systems that are practical, explainable, and production-minded — not just demos.

I work at the intersection of:

🔎 Retrieval-Augmented Generation      🤖 Agentic AI & Tool-Using LLMs
📄 Document Intelligence & OCR         👁️  Computer Vision & Real-Time Inference
⚙️  Backend APIs for AI Products        📊 Applied ML & Data Systems

Previously worked with enterprise data and ML pipelines at IBM, and fraud detection systems at PayPal, gaining hands-on experience with Python, SQL, production ML, and stakeholder-facing reporting.

🚀 Featured Project

🎯 CareerGraph AI — Recruiter Matching Platform

An AI-powered QR portfolio that turns a static resume into an interactive recruiter experience. Recruiters scan a QR code, paste a target role or JD, and instantly see which projects prove candidate-role fit.

Highlights: Role-based project matching · JD match mode · Reviewer snapshot · Lead capture dashboard · Follow-up suggestions

🌆 Music-Driven Cityscape Visualization

📄 Published research prototype

Real-time audio-reactive visualization inspired by the city of Passau. Extracts RMS, tempo, beat, and spectral centroid features and maps them to synchronized procedural visuals — 55-65 FPS on commodity hardware.

Python Librosa SciPy Pygame Signal Processing

🎮 Gesture-Controlled Game System

Real-time body gesture recognition for interactive gaming. MediaPipe Pose landmark extraction with rule-based and ML gesture classification, stabilized with buffering and majority voting.

OpenCV MediaPipe scikit-learn KNN Random Forest

🥽 UXRVT — Unity XR Visualization Toolkit

Unity-based toolkit for immersive 3D data visualization, inspired by D3.js concepts. Supports interactive 3D exploration for XR/AR visual interfaces.

Unity C# XR Data Visualization
