About

About

I'm a senior full-stack engineer based between Lagos and Canada, working remote-first. Most of my work sits where storefronts, browser tooling and back-office systems meet: custom Shopify themes in Liquid tuned for conversion, and API integrations that connect Shopify, HubSpot, Airtable and internal tools so data moves without manual handling.

I build Chrome extensions to Manifest V3 standards, from productivity tools to full SaaS products with Firebase auth and Stripe billing wired in. Underneath sits Java (Spring Boot) and Go services, PHP/WordPress and NestJS APIs, backed by PostgreSQL and MySQL, with Flutter on mobile to keep iOS and Android on one codebase.

I've worked with teams at Andela, Interswitch, AppRiver, OLISystems, Wondr LLC and Leaps & Bounds, and I'm Top Rated on Upwork with a 100% Job Success Score. I stay close to the stack end to end, storefront to service to app, so nothing gets lost in the handoff.
