Projects

Maihomm – Real Estate Platform

Designed and developed the backend for a real estate platform that enables property listing, search, and management at scale. Implemented secure authentication, advanced filtering, and real-time property availability to deliver a seamless user experience. Built APIs that power both web and mobile clients, ensuring fast response times and high reliability. I focused on scalability and performance, implementing caching strategies, optimized database queries, and modular API design. The system was engineered to handle thousands of concurrent property searches and transactions without performance degradation. Tech Stack: Node.js, TypeScript, MongoDB, Redis, Docker, AWS (EC2, S3), JWT Authentication

OWU Sportswear - E-commerce website

Built the backend system for OWU Sportswear, an e-commerce platform enabling product catalog management, order processing, and secure payments. Designed a scalable API layer to power both web and mobile applications, ensuring seamless shopping experiences with real-time inventory tracking. The backend was engineered with high performance and security in mind from payment gateway integration and JWT-based authentication to optimized product search and filtering. Implemented caching strategies to reduce load times and improve responsiveness during peak sales periods.

Language App

An app designed to make learning the Yoruba language accessible, engaging, and culturally immersive. The app combines audio lessons, interactive quizzes, and real-life conversation scenarios to help users build fluency step by step. It supports both beginners and heritage speakers looking to reconnect with their roots, with features like speech recognition for pronunciation practice, progress tracking, and cultural context modules that go beyond vocabulary. The project demonstrates skills in backend API design, authentication, media handling, and scalable architecture, ensuring a seamless, production-grade experience for global learners.
