I build the systems
behind the product.
I design and build production software end to end: multi-tenant platforms, marketplaces, and the payments and infrastructure underneath them.
production platforms built solo, schema to CI/CD
payment and escrow systems integrated end to end
SaaS architecture serving many tenants on one codebase
infrastructure and deployment owned, not handed off
What I actually build with
Not a skills wishlist, the stack that actually shows up across the ten platforms on this site.
Frontend
Interfaces built with Next.js and React for real product complexity, not static pages.
Backend & APIs
Service architecture and REST APIs in Node.js, modeled around real domains.
Data & Storage
Schema design and query performance for systems that hold real records.
Payments & Commerce
Stripe, Stripe Connect, and Paystack, including escrow and split-payment logic.
Realtime & Background Work
Sockets and job queues for the parts of a product that can't wait on a request.
Infrastructure & DevOps
From Dockerfile to CI/CD to a server I actually deployed it on.
Experience
Six roles, one thread: owning a system from architecture to deployment, not just the parts that show up in a demo.
CTO
SmartEdu
Leading product and engineering for a multi-tenant school-management SaaS platform serving schools across Africa. Own the architecture end to end: a subdomain-per-tenant Node.js and PostgreSQL backend, a Turborepo of Next.js frontends, and the Paystack billing model the business runs on.
Systems Engineer
Aptfuel
Own the full application lifecycle across mobile, backend, and frontend. Built CI/CD pipelines, managed deployments, and broke down complex features across applications while driving technical decisions.
Senior Full Stack Engineer, Architecture Lead
Raffles Energies
Led end-to-end architecture and backend development for web and mobile platforms. Architected the Node.js backend and database schema from inception, implemented Redis caching and asynchronous job processing, and managed containerized production deployments.
Backend Engineer
Centre for Innovation & Entrepreneurship
Scaled a Laravel-based learning management system supporting multi-center operations for a government organization, redesigning the relational schema to support expanded roles and institutional structure.
Full Stack Engineer
Alphatrol Limited
Took Guardtrol, a real-time multi-location monitoring system, from concept to production. Designed RESTful APIs and MongoDB/MySQL schemas, and implemented JWT-based authentication and authorization.
Frontend & Backend Engineer
Nexlen Systems
Migrated a legacy Laravel Blade codebase into a structured Vue.js frontend system, integrating it with backend APIs and reducing redundant requests to improve UI performance.
Selected work
Four platforms that show the range: multi-tenant SaaS, a vetted marketplace, an institutional LMS, and a travel platform shipped in deliberate stages.
SmartEdu
A multi-tenant school-management platform for schools across Africa, from fee collection to parent communication, on one subdomain-per-school architecture.
FairChild
An institutional learning management system built for FairChild Institute: separate student, instructor, and support portals on one shared backend.
QiblaCore
A Hajj and Umrah travel platform, architected as three apps and shipped one at a time, starting with the one that had to exist first.
VerraEarth
A vetted marketplace for makers: sellers prove their goods are actually handmade, and payments split automatically between the platform and the vendor.
Let's build something worth shipping.
Open to senior and lead engineering roles, systems work, and projects that need someone comfortable owning a problem from architecture through to production.
