Some of my most impactful work
Tutorial Haven is a comprehensive EdTech platform helping Nigerian students prepare for JAMB, WAEC, NECO, and O'Level exams. With 615+ active students, ranked by ChatGPT as one of Nigeria's top 3 practice platforms, and AI-powered recommendations driving traffic. Features include past question drills, personalized learning, real-time tutoring, mock exams, subject notes, and the newly launched Tutorial Haven Arena—a gamified social learning subdomain with features like dueling quizzes, squad battles, leaderboards, daily missions, and more.
LagSciPrep is a comprehensive Computer-Based Testing (CBT) platform developed specifically for science students at the University of Lagos. It features objective questions across biology, chemistry, physics, and more. With 195+ active students, 100% daily retention, and strong organic growth, the platform offers customizable mock exams, real-time progress tracking, and detailed result analytics to help students prepare effectively.
OjaPass is a full economic identity platform designed to bring Nigeria's informal workers into the formal financial system. Built in just 10 days during the Squad Hackathon 3.0, the platform features a Bayesian credit scoring engine, gig marketplace with escrow, digital Ajo savings, micro-loans, and Squad API integrations to assign virtual accounts instantly.
A secure and anonymous platform for reporting issues and making your voice heard without fear of retaliation.
Inventrii is a lightweight inventory management solution built for informal vendors, small business owners, and retail stores. It allows users to easily add products, scan barcodes using their camera, track sales, update stock in real-time, and view sales analytics. Designed with simplicity and mobile-friendliness in mind, Inventrii helps everyday retailers stay organized and sell smarter — even offline.
From 1,600 applicants to the shortlisted 250. Here is what happened.
This was my first hackathon — and my entire team's first. Out of over 1,600 applications, Team SmartFlow was shortlisted to compete in person in Lagos. We spent sleepless nights building OjaPass, a full economic identity platform designed to bring Nigeria's 90 million informal workers into the formal financial system.
Six Squad API integrations. A Bayesian credit scoring engine. A gig marketplace with escrow. Digital Ajo savings. A loan engine with real amortisation logic. AI-powered job matching via Gemini. All of it — in under two weeks.
We ranked 77th overall. We didn't make the semifinals. But we walked away with something worth more than a podium — the ignition. The proof that we can build real things that solve real problems for real people.
