Building AI that actually works in production.

I am a Data Scientist and AI Engineer based in Lagos, Nigeria with 5 years of experience building and deploying machine learning systems across fintech, HR analytics, healthcare, and retail.

At Flutterwave, one of Africa's most recognised fintech platforms, I build fraud detection models processing millions of daily transactions across African markets. At Andela, I deliver LLM applications, RAG pipelines and agentic workflows for international enterprise clients.

Before moving into data science, I spent several years as a bilingual investment analyst. That background means every model I build is connected to a real business outcome, not just a benchmark score.

I am trilingual in English, French and Spanish, and currently enrolled in a BS Computer Science at the University of the People. Open to remote roles globally. Visa sponsorship required.
