Selected Work

Shipping · Web App · 2024

Harbouline Shipping

A full-service shipping platform enabling users to book shipments, track packages in real time, and manage their accounts — fully responsive and accessible across all devices.

Problem

No centralized online platform for users to book, track, or manage shipments efficiently and transparently.

Solution

Responsive shipping platform with booking flows, real-time package tracking, and account management — built with accessibility and UX first.

BanexAI

AI-powered recruitment platform that helps employers discover, assess, and hire top talent — while giving job seekers AI-optimised CVs, smart job matching, and interview prep tools.

Problem

Traditional hiring is slow, bias-prone, and guesswork-heavy — employers waste hours screening CVs while qualified candidates go unnoticed.

Solution

Built a full-stack SaaS: Next.js frontend for a fast, SEO-friendly experience and a Node.js backend driving AI talent matching, automated CV screening, smart assessments, and data-driven hiring dashboards.

WebRTC peer-to-peer video chat application

WebRTC · Socket.io · Node.js · React · 2025

WebRTC Video Chat

Production-ready peer-to-peer video calling app with a React frontend and a Node.js + Socket.IO signaling server — deployed as a split architecture for reliable real-time media across restrictive networks.

Problem

STUN-only WebRTC fails for users behind corporate firewalls and strict NATs — most production video apps silently break without a proper TURN relay fallback.

Solution

Split deployment: React client on Vercel, signaling server on a dedicated Node host. Configurable ICE servers with TURN support ensure connectivity for all network conditions.

WebRTC React Socket.io Node.js TURN/STUN

3D · Three.js · WebGL · 2024

3D Geometry Explorer

Interactive 3D geometry showcase rendering complex geometric shapes in real time — built for developers learning WebGL and 3D graphics on the web.

Problem

Three.js and WebGL concepts are abstract and hard to learn without live, interactive, well-structured examples to explore.

Solution

Interactive showcase with real-time 3D geometry rendering — giving developers a hands-on reference for working with WebGL in the browser.

Ideal Diagnostics

Diagnostic Center Management System built on Clean Architecture — an Avalonia desktop client backed by an ASP.NET Core 8 Web API and PostgreSQL, covering the full workflow of a diagnostics facility.

Problem

Diagnostic centers rely on fragmented paper-based or outdated systems that slow down patient intake, test tracking, and results management across departments.

Solution

Cross-platform desktop app with a clean API backend — Entity Framework Core handles data integrity, Swagger documents every endpoint, and Clean Architecture keeps business logic independent of infrastructure.

About

I'm a software developer based in Abuja, Nigeria, with a background in Mechanical Engineering — a combination that gives me a disciplined, systems-level approach to building software. Over 5+ years, I've shipped production applications for companies across security, healthcare, and fintech, consistently delivering clean, performant interfaces on schedule.

Currently building at Quadratix Limited in Lagos, where I took ownership of an uncompleted project and led it to a successful client launch — implementing modules, integrating APIs, and introducing CI/CD practices. I work across the full stack — from system architecture and API design to polished interfaces that users actually touch.

Experience

Professional roles across security, healthcare, and software — delivering production-grade systems in real working environments.
