Building Production Systems
From Database to Interface.
Frontend engineer at StudyItLive, shipping features used daily by students and educators. I work across the stack—React, TypeScript, NestJS, Supabase—to build systems that scale and stay maintainable.
About
I'm a frontend/full-stack engineer based in Nigeria. I build production systems designed for long-term maintainability—clean architecture, consistent patterns, and documentation that makes handover straightforward.
I've worked in product teams, shipped under deadlines, and maintained codebases well beyond initial launch. My code is written to be extended by other developers, not just understood by me.
Currently open to remote roles and short-term contract work.
What I Work On
Production Frontend Systems
React/Next.js applications built for performance, accessibility, and team scalability
Full-Stack Feature Delivery
End-to-end implementation from database schema to user interface
Data-Driven Interfaces
APIs, real-time data, and complex state management in production environments
Maintainable Architecture
Code patterns and documentation designed for team handover and long-term extension
Cross-Functional Collaboration
Working with product, design, and backend teams to ship on schedule
Selected Work
StudyItLive
A live online learning platform serving thousands of students and educators—comparable to Coursera or Udemy. Currently in production with active daily usage.
My Role: Frontend Engineer. Implementing features across the React frontend, coordinating with backend engineers on NestJS services, and shipping production-ready code in a team environment with shared ownership.
The Challenge
Legacy frontend architecture causing friction between teams. Feature velocity was limited by tight coupling and inconsistent data flow.
Production Impact
Stabilized data flow between client and backend services. Features I shipped are used daily by students and educators in an operational learning environment.
SportPreds
A sports prediction system with live fixture data, statistical modeling, and real-time match ingestion. Designed as an end-to-end architecture, not just an interface.
My Role: Sole engineer. Architected the full system: database schema, data ingestion pipeline, prediction logic, API layer, frontend application, and deployment infrastructure.
The Challenge
Build a production-ready prediction platform with live data ingestion and mathematical modeling—without indefinite development cycles.
System Outcome
Launched a working platform with automated fixture syncing, a statistical prediction engine, and a clean user interface. Full ownership from schema design to production deployment.
Tech Stack
React.js
Next.js
TypeScript
NestJS
Supabase
MongoDB
Tailwind CSSStandard, maintainable tools. Any team can onboard and continue the work.
