I joined the TeamApt division as a Software Engineer in October 2023 and was promoted to Senior in September 2025. I work on most of the life of a card transaction: preparing chip data before a card is issued, authenticating the cardholder online, clearing transactions with Mastercard and Visa, and answering disputes inside scheme deadlines. I build the services, and the React interfaces that operations teams use to run them.

I worked on Omeife AI, a multilingual platform for African languages, with real-time chat, voice and video translation, and automatic multilingual subtitles. I also helped launch DigiLiteracy, a digital-education platform, and brought Omeife into it so learners could use AI in local languages. It reached more than 2,000 active users.

React, JavaScript, TypeScript

A paid open-source internship. I modernised MapKnitter Lite, the JavaScript module behind Public Lab's tool for stitching aerial photos into maps, refactoring code that carries more than ten years of legacy mapping data. I added access to archived datasets through the Internet Archive API, drag-and-drop upload for multiple images, and a paginator for working with images in bulk. Sixteen of my pull requests were merged into Leaflet.DistortableImage, and I worked in the open with the maintainers through issues and code review.

Client work across web and mobile: a banking web application for a microfinance bank, with role-based access control; an interactive land-allocation map built on Leaflet; and the Oriztech Wellness mobile app, with personalised health plans, activity tracking and token-based rewards.

React, React Native, Laravel

Avela sells solar, security and smart-home systems in Nigeria and Ghana, with instalment financing built in. I built and deployed the platform: a modular NestJS backend, a Next.js frontend, and the pipeline that ships them.

SwipeKlin connects customers in Canada with nearby cleaners. I built and maintained its two React Native apps, one for customers and one for cleaners, along with real-time booking updates, Stripe payments and payouts, and deployments of the Laravel backend behind them.

Coursemate answers students' questions from their own course material, inside Canvas through LTI. When a question looks like a request for assignment answers, it redirects rather than refuses. It started as a tool for my own MBA courses and is in active development.

Master’s project: Tokenization middleware

Self-hosted middleware that lets a Nigerian small business store tokens instead of permanent identifiers such as BVNs, designed around the Nigeria Data Protection Act 2023 and the GAID 2025. It exposes three operations, tokenize, detokenize and erase, over TLS behind scoped API keys, with a rate limit and an append-only audit log. During research I discovered format-preserving encryption and tokenization. Further research showed that FF3 had been weakened by cryptanalysis near the length of the identifiers I was protecting, so I chose tokenization instead.
