01About
Teacher by training. Builder by obsession.
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 three 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 used by 650 Flour Mills of Nigeria employees processing ~₦3.56M a month, and a marketplace app at Sage Grey Technologies whose users grew 350%. 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
From idea to production, end to end.
I work across the stack so nothing gets lost between design, API and device.
02
APIs & backends
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.
03
Payments & integrations
Paystack, Moniepoint, Moniebook POS, Chowdeck delivery, Twilio WhatsApp, Zoho, HubSpot and WooCommerce — the glue that turns an app into a business.
04
Applied AI & automation
Chatbots and AI agents built on LLM APIs, offline speech recognition, and WhatsApp bots that take orders while your team sleeps.
03Selected work
Things I've shipped.
Production systems for enterprises, retailers, churches, campuses and government — most of them live right now.
