About

I am a computer scientist with expertise spanning agent-based simulation, software quality engineering, and intelligent systems design. My master's thesis at TU Clausthal modelled emergency evacuation dynamics across five lecture-hall layouts — incorporating panic contagion, herding behaviour, and a Dijkstra-variant pathfinding engine.

On the engineering side, I have hands-on experience in test automation (Selenium WebDriver, JMeter, Burp Suite) and CI/CD integration (Jenkins, GitHub Actions), alongside three years as a software developer and technical trainer at Matrix Technologies — supervising end-to-end Java projects and building structured training curricula.

My stack spans Java, Python, test automation tooling, and the full web platform, with a consistent thread of rigorous thinking and clear technical communication.

Emergency Evacuation Simulation

Master's Thesis · TU Clausthal · 2025

A large-scale agent-based simulation modelling emergency evacuation dynamics across five university lecture-hall layouts. The system incorporates heterogeneous agent populations — students, professors, mobility-impaired individuals — each with distinct panic thresholds, familiarity coefficients, and movement speeds. Core engine: a Dijkstra-variant pathfinding algorithm with real-time rerouting under congestion. Panic contagion and herding dynamics are modelled as emergent social phenomena. Over 9,000 parameterised experiments conducted via BehaviorSpace.

Key finding: Modern multi-aisle layouts with symmetrical exit placement reduce median evacuation time by up to 38% versus traditional single-aisle configurations. Herding behaviour degrades performance even in well-optimised layouts.

Pathfinding Visualizer

Interactive Tool · HTML / JavaScript

Browser-based interactive tool rendering graph traversal algorithms step-by-step on a live grid. Demonstrates the same pathfinding principles used in the thesis simulator — making abstract algorithmic behaviour immediately tangible. Zero dependencies; built on the native Canvas API.
