Projects

Portfolio Project · 2025
Berlin Traffic & Mobility Dashboard
Data Visualisation JavaScript Chart.js Open-Meteo API Simulation

An interactive traffic and mobility control-room dashboard for Berlin, demonstrating data engineering and visualisation skills. Features four analytical views — Overview, Public Transit, Road Network, and Analytics — with live weather data pulled from the Open-Meteo API. Traffic and transit data uses realistic Berlin peak-hour simulation profiles.

Thesis Research · 2022–2023
Intelligent Traffic System
YOLOv5 Bee Colony Optimization Computer Vision Python

Trained a YOLOv5 object detection model on 113,888 annotated traffic light images to detect and classify traffic conditions in Ghana. Paired with a Bee Colony Optimization algorithm to dynamically optimize signal phasing, reducing average vehicle wait times in simulation by 32%.

Research Interest

How can ML and AI be applied not just to understand trade and logistics systems — but to actively optimize them, removing friction, predicting failure, and making supply chains smarter in real time?

My research sits at the intersection of machine learning, combinatorial optimization, and operational intelligence — applied to trade and logistics, where inefficiency is costly and data is underutilized. The thesis above is the first proof of concept. Future directions include hybrid RL + metaheuristic solvers for freight routing, supply chain early-warning systems, and real-time data integration architectures for trade operations.
