About

I work best sitting next to the people who have the problem. At Venture Garden I led the planning, testing and launch of fintech platforms that disburse and receive more than 2 million international payments across Africa and Europe, and met 100% of our SLAs by staying close to the clients who ran them.

Today I am co-founder of Owl Express, which turns WhatsApp and Instagram chats into orders, payments and deliveries for African small businesses. I also build AI features and data services in Python at Parser, and earlier trained machine learning models that cut a football club’s analysis from two weeks to 20 minutes.

I design and build software end to end: C# and .NET services, React, Vue and Angular front ends, PostgreSQL, and the CI/CD that ships it. Over a decade I have delivered 150+ web APIs and 30+ web applications, and led architecture and delivery teams across fintech, data and AI, health and IoT.

Owl Express is my current build: a .NET 10 modular monolith with a Vue 3 front end, PostgreSQL with PostGIS, RabbitMQ and automated deploys to production and test environments. It is multi-tenant, with each business’s data isolated at the query level.

Projects

Live demo: chat to order, with AI

A customer messages a fictional shop on WhatsApp. An AI model reads the message. Prices, totals and next steps come from plain rules, the way I build Owl Express. Type your own message or pick a sample, and watch the API call beside it.

Demo Store WhatsApp, simulated
Request
POST /api/demo-order
// sent when you send a message
Response
// the structured order appears here

The shop, its prices and the replies are simulated for this demo, and the endpoint is rate limited.

WhatsApp and Instagram become a sales operating layer for African SMEs. A deterministic booking engine collects order details, a dispatcher approves from a web dashboard, a rider completes the job in a mobile app, and proof of delivery returns to the same place.

This site and its AI assistant

The page you are reading. Ask Ayoola AI answers recruiter questions from a curated fact sheet and refuses to guess. The chat-to-order demo has an AI model read the customer message while plain rules compute prices and next steps. Both routes are rate limited and fall back safely when the model is unavailable.
