What I'm looking for

I'm looking to contribute to end-to-end data science, machine learning, NLP, and RAG projects where I can turn reliable data pipelines and predictive models into practical business insights.

I've built privacy-focused Retrieval-Augmented Generation systems at the University of Westminster, using Python, FAISS, PyMuPDF, and open-source LLMs from OpenRouter to support secure multi-document parsing. I also analysed 110,527 Brazilian hospital records, identifying operational factors associated with appointment attendance.

At Hamoye AI Labs, I deployed four end-to-end machine learning models across supervised and unsupervised tasks. At joblag.com.ng, I automated manual data entry with Python and Selenium, increasing data throughput by 80%, while my Power BI conflict dashboard surfaced casualty trends across 2021–2024.
