Senior full-stack engineer with 10+ years shipping scalable apps, integrations, and automations for ambitious clients worldwide — Top Rated on Upwork with a 100% Job Success Score.
Custom Shopify theme development in Liquid, tuned for conversion rather than templated defaults. API integrations that connect Shopify, HubSpot, Airtable and internal tools so data moves without manual handling.
Chrome extensions built to Manifest V3 standards, from productivity tools to full SaaS products with Firebase auth and Stripe billing wired in.
Underneath sits full-stack engineering: Java (Spring Boot) and Go services, PHP/WordPress and NestJS APIs, backed by PostgreSQL and MySQL. On mobile, Flutter keeps iOS and Android on one codebase instead of duplicated logic per platform. I stay close to the stack end to end, storefront to service to app, so nothing gets lost in the handoff.

Real feedback from Upwork engagements.
"Okeowo is an exceptional developer. He understood exactly what we needed, delivered ahead of schedule, and the extension works perfectly. He also proactively flagged a UX issue we hadn't noticed."
"Our Airtable base was a mess. Okeowo rebuilt the entire architecture, wrote clean scripts, and documented everything. Our team now saves 10+ hours a week. Will absolutely hire again."
"The Shopify work was impeccable. Clean Liquid code, no bloat, and the store launched on time. He communicated throughout and raised zero issues we had to chase. A genuine pro."
Every engagement follows the same structured approach — so you always know where we are.
We spend 30 minutes understanding your goals, constraints, and what success looks like. No cost, no commitment.
I send a detailed scope document with timeline, deliverables, and a fixed or hourly quote — whichever suits your project.
Weekly check-ins, async updates, and staged deliveries. You see progress early and often — never at the end.
Clean handoff with documentation, training where needed, and post-launch support to make sure everything runs smoothly.
