Onamini (GigScholars) bridges businesses with talented college students for short-term, paid gigs—helping students build professional networks while businesses get work done efficiently. I architected the escrow and milestone payment system by designing database schemas in MySQL, enforcing relationships with foreign keys, and writing optimized queries to ensure reliable, secure transactions. I developed RESTful APIs using Node.js and Express, applying modular controller-service patterns to handle onboarding flows, milestone approvals, and project management endpoints. I integrated file uploads with 'express-fileupload', implementing middleware to validate file types, sizes, and securely store company profile and environment documents. I also designed milestone approval workflow by writing backend logic that checks deliverables, validates client confirmation, and triggers payment release via escrow system. I improved database performance by analyzing query execution plans, restructuring indexes, and normalizing tables to reduce redundancy and speed up response times. Ensured code scalability and maintainability by organizing routes, separating concerns into models, controllers, and services, and documenting API endpoints with clear usage guidelines. Tested endpoints extensively with tools like Postman, creating structured test cases to validate authentication, request/response cycles, and error handling before deployment.

Intel Region Media & Tech Company provides cutting-edge media and technology solutions, utilizing PHP and Laravel for backend development. Built and optimized high-traffic APIs in PHP (Laravel) to support media streaming and content management, applying caching strategies and query optimizations for smoother performance. Designed scalable RESTful APIs using Laravel’s routing and middleware features, ensuring secure, reusable, and consistent communication between frontend applications and backend services. Implemented backend solutions by leveraging Laravel’s ORM (Eloquent), queues, and service container to handle complex business logic efficiently. Improved database performance by profiling slow queries in MySQL, adding proper indexes, and refactoring joins/aggregations, resulting in faster data retrieval and reduced server load. Integrated third-party APIs (e.g., payment processors, media tools) by building reusable service classes, handling authentication tokens, and managing API rate limits for reliability. Enhanced backend scalability and maintainability by modularizing code into services and repositories, implementing unit testing, and documenting API endpoints for team-wide collaboration.

Ajuoza is a mobile application that helps users locate missing persons and important documents, with a strong emphasis on family security. Designed and implemented backend infrastructure for a multi-user educational platform (students, tutors, admins). Built RESTful APIs for authentication, profile management, and live session updates. Engineered a booking and scheduling system with conflict-free logic, automated notifications, and payment triggers. Integrated secure payment gateway (PayPal) for transactions, payouts, and invoicing. Developed real-time classroom features (video, audio, whiteboard) using WebSockets. Designed and optimized database schema for users, sessions, reviews, and tutor qualifications. Implemented advanced search and filtering across 15+ tutor criteria. Built notification engine for email & push alerts, boosting retention and engagement.

Icitify Solutions Limited develops modern management systems and digital learning tools to enhance organizational productivity. I developed and documented APIs for a suite of management and e-learning tools to ensure secure and efficient functionality. I also built APIs using Node.js, Express, and MongoDB, with a focus on scalability and performance. I implemented real-time communication for chat and notifications using WebSocket and Socket.io. I collaborated effectively with remote teams on GitHub for seamless code integration and version control. I delivered a well-documented, functional API suite that enhanced the tools, boosting user engagement and productivity.

Prolific offers task management solutions that streamline operations for users through advanced reminder and notification systems. Optimized database performance to support fast query processing and seamless third-party service integration. Designed a normalized MySQL database and implemented indexing to boost query efficiency. Integrated secure payment services using Flutterwave and enhanced authentication with OAuth and JWT. Significantly reduced database query time, leading to faster API response times. Improved overall system reliability, creating a streamlined and secure user experience.
