Maverick IMDB Auto-Fill
A Streamlit app that turns product imagery into Item Master Database submissions. It groups images by product evidence, runs multimodal extraction and barcode scanning, normalizes fields, supports human review and duplicate handling, and exports CSV or Excel files. (Built for the GDSS-Maverick Hackathon at IndabaX Ghana 2026.)

LingoShadow
A daily language practice app that turns your real routines into useful target-language sentences, audio, and a downloadable study pack. Built during the Build Small Hackathon as a Gradio app with language-specific routing for generation, translation, and text-to-speech.
Legislation Explainer
A plain-language legislation assistant that summarizes dense bills, explains their practical impact, and supports follow-up questions. Built for the Build Small Hackathon to help regular people make sense of legal documents without needing to parse the whole thing themselves.
Africa Youth Employment Clock
The Africa Youth Employment Clock is a Mastercard Foundation project executed by the World Data Lab (WDL) to track and predict employment trends in Africa, and help policy-makers to make data-sriven decisions. At WDL, I led the data engineering and data science work for Ghana and Nigeria with sub-national granularity, including data acquisition, modelling and visualization, as well as presentations at the international launch events.
Document Semantic Search
Used multilingual embeddings to build a RAG tool for running semantic searches across multiple documents in order to answer questions based on the said documents with compatibility for 100+ languages.
This project won 1st place in the #CohereAIHack
CYI IT Projects (Tech Lead)
CYI is a Christian youth development organization based in Accra, Ghana, with branches across Africa and Europe. I lead development on a number of WordPress projects and JavaScript projects linked by a central API built from the ground up.

UNet Foreground Image Segmentation
A TensorFlow project from 2020 using a modified UNet autoencoder architecture with MobileNetV2 weights to perform transfer learning for foreground image segmentation. The original usecase was polyp segmentation from colonoscopy images, but this was repurposed for foreground segmentation of everyday objects.
