I designed and built Nexo, a Nigerian multi-vendor marketplace, from the ground up. I handled its backend architecture, API design, and system logic, including split payments, a tiered commission engine, fraud detection, dispute resolution, and a token-based referral economy.
I built Snatched Africa, a Flutter wellness app for African women, from product requirements through Google Play submission, alongside a non-technical co-founder. It includes a food scanner for local African foods and subscription billing, alongside progress tracking and a companion React marketing website.
