About

Shipping production code since 2020.

I'm a senior software engineer with 6+ years shipping production systems across fintech, EdTech, and SaaS. I build complete products end to end, and increasingly the AI systems and agent integrations running inside them.

I have been programming since 2018. However I started shipping production code from 2020 contributing to FightPandemics, an open-source platform built by a distributed team of volunteers. From there I moved to Loctech, building modules for a haulage ERP. Since then I've shipped payment rails, auth, schemas and deploys across every product I've worked on.

I think like a product owner, not just an implementer. I've taken products from concept through deployment and go-to-market, not just through tickets.

AI is part of how I work. I break work into pieces an agent can handle, give it the right context, and review every generated change before it ships. AI speeds me up; it doesn't replace my judgment.

I own what I build past the code: the scope, the payment flows, the cloud bill, and what happens when something fails.

Selected work

Three products, end to end

Syncshare

syncshare.app

Cross-platform post scheduling. Write once, publish to LinkedIn, Threads, TikTok and more.

Solo-built

Next.js frontend and admin dashboard, backend on Firebase Functions, Express.js and Node.js.
LinkedIn, Threads and TikTok API integrations, each built to that platform's own publishing rules.
Background scheduling engine that publishes posts at their set time and notifies the user when a publish fails.
Paystack subscription billing in both USD and NGN.
AI-powered content suggestions and a media library for scheduling.

Standout

Syncshare MCP: a working MCP server that lets users schedule posts straight from a Claude chat window through the Syncshare API.

Pedagic

Algoryhtyme, African Institute for AI

School management platform for teachers, administrators, parents and students.

Owned the architecture

Owned the end-to-end architecture (Dec 2025 to Jul 2026): Next.js frontend and NestJS backend.
Set the service boundaries for three Python FastAPI microservices (Teacher Copilot, Student Copilot, Timetable API), and integrated them into NestJS.
NestJS is the central data broker and sole JWT authority, so no microservice talks to users or issues tokens directly.
One PostgreSQL instance running four schemas.
Worked with an ML engineer building the AI services, a backend developer on platform services, and a product engineer.
Turned product and school-operations requirements into technical scope alongside the product team.

Human check in the loop

AI-generated assignments and practice questions are reviewed by a teacher before anything reaches a student.

Team of 5

Rebuilt payment infrastructure end to end: checkout on Paystack and Flutterwave, plus an automated payout system for vendors.
Set up the cloud services and deployment environment for the version 2 platform.
Refactored cloud services on Vercel and Firebase Functions, cutting cloud costs.
Coordinated a 5-person cross-functional team (design, product, full-stack, backend, QA) building a new platform from zero.
Reworked the delivery fulfilment flow and integrated lower-cost delivery options.
Kept the existing platform stable during the rebuild, working with relationship managers so vendors and customers saw no disruption.

Payouts are safe to retry

Unique transfer references block double payouts, failed transfers retry automatically, and webhook signatures are verified before any payment state changes.
