AI Engineer & Solution Architect building scalable systems for African markets.

About Me

I'm an AI Engineer at Qucoon — where I design and ship production AI systems that handle real financial transactions, real users, and real edge cases. My background in mathematics gives me first-principles understanding of the models I build — not just the APIs I call. I build things that work in Nigeria, where internet is unreliable, data is scarce, and most global AI tools were never built with us in mind. Currently working on: A multilingual conversational AI for Yoruba, Igbo, Hausa, and English — voice-in, voice-out, no keyboard required.

My Experience

Production AI systems, research consulting, and data analytics. Real work, shipped solutions.

Qucoon

March 2025 - Present

AI Engineer & Solution Architect

Architected a 5-agent AI customer support system for fintech — Intent Classifier, Conversation Bot, Product Bot, Support Bot, and Escalation Agent. Built multi-step chain-of-thought workflows with Redis memory, concurrent async execution, and LLM response validation with automatic fallbacks. Also shipped a document Q&A system using RAG with confidence scoring and FastAPI REST APIs.

Upwork

Dec 2024 - Oct 2025

Freelance AI / Research Consultant

Delivered completed 5.0-rated Upwork engagements, including an AI-powered coding course review and a job-posting research project for Gujarat, India. Worked quickly, communicated clearly, and turned ambiguous requests into actionable deliverables.

B.Sc. Mathematics & Education

Studied mathematics with a focus on statistical modeling, linear algebra, and computational methods — the foundation that makes my ML work tick. Applied mathematical thinking to real-world data problems throughout my studies.

Production Work at Qucoon

Production AI systems built for fintech support and knowledge retrieval.

5-Agent AI Customer Support System

Production

Designed and deployed a multi-agent pipeline — Intent Classifier → Conversation Bot → Product Bot → Support Bot → Escalation Agent — with Redis persistent memory, concurrent async execution, LLM response validation, and automatic fallbacks.

Projects

Here are some of my projects where I've turned code into cool, functional stuff.

Dr. Amina — AI Healthcare for Northern Nigeria

648 health documents · 80% confidence threshold · Hausa voice input

Built a medical RAG chatbot that serves Northern Nigeria's underserved communities. Powered by Google Gemini and Pinecone (648 verified health documents), it detects emergencies with 80% confidence, supports Hausa voice input, and persists conversations via Supabase. Deployed live on Streamlit for the DataFest Africa 2025 Hackathon.

Fighting Fraud with Machine Learning

1M+ transactions · 0.3% fraud rate · 38 engineered features

Built a production-grade fraud detection system on 1M+ interbank transactions with a 0.3% fraud rate — no synthetic balancing tricks. Engineered 38 behavioral features, trained interpretable models (Logistic Regression → Random Forest), and used SHAP to make every flagged transaction explainable to analysts and regulators.

What I'm Building Next

A closer look at the next product direction I'm pushing toward.

Nigerian Multilingual Conversational AI

Most Nigerian AI products wrap an English LLM and call it localized. That is translation lag, not localization.

I am building voice-in, voice-out conversational AI that natively understands Yoruba, Igbo, Hausa, and Nigerian English — not as translated inputs, but as primary languages.

First milestone: A conversational finance tracker in Pidgin English and Yoruba, connected to Nigerian bank APIs — deployable in 2026.
