Web & mobile apps
Products in React, Next.js and React Native (Expo) — one typed codebase mindset across browser and phone, fast on cheap devices and slow networks.
Hi, I'm Anthony Olasunkanmi Ogunleye — a full-stack & AI engineer from Nigeria. I ship web, mobile and backend systems that real businesses run on — WhatsApp commerce, payments, POS, attendance and offline AI — from the data model to deployment.
01About

English
Yoruba
I'm Anthony — known online as DprinceDeveloper. I trained as a Computer Science educator at Ekiti State University, and that shapes how I build: I start with the person using the thing, then work backwards to the code.
Over four years I've built production systems for startups, enterprises and 25 freelance clients: a WhatsApp ordering bot handling 5,000+ orders a month, a staff storefront for Flour Mills of Nigeria wired to Moniepoint and POS terminals, and a marketplace app at Sage Grey Technologies whose users grew 300%. I work in TypeScript, React, React Native, Node.js, NestJS and Python, and I'm increasingly focused on applied AI.
Beyond code, I lead. I served as President of the Sandwich Students Association at EKSU, led cohorts at the Ekiti State Digital Skilling Academy, and still mentor developers starting out — because the best software, like the best teaching, makes hard things feel simple.
“Solid methodologies, websites that stand the test of time, and users who leave happier than they came.”
02What I do
I work across the stack so nothing gets lost between design, API and device.
Products in React, Next.js and React Native (Expo) — one typed codebase mindset across browser and phone, fast on cheap devices and slow networks.
Node.js, NestJS, Express or FastAPI services with JWT auth, rate limiting, validation and clean data models on PostgreSQL or MongoDB — containerised and shipped with CI/CD.
Paystack, Moniepoint, Moniebook POS, Chowdeck delivery, Twilio WhatsApp, Zoho, HubSpot and WooCommerce — the glue that turns an app into a business.
Chatbots and AI agents built on LLM APIs, offline speech recognition, and WhatsApp bots that take orders while your team sleeps.
