What I'm looking for

I’m looking for a team where I can build scalable, user-centric web apps with strong engineering practices—secure APIs, performance improvements, and AI-integrated features—while collaborating in an agile, cross-functional environment.

I’m a results-oriented full stack developer with hands-on experience in TypeScript, React, Node.js, and AI-integrated applications. I delivered scalable, accessible solutions in HNG Internship 11, ranking in the top 500 out of 20,000+ interns while focusing on education and media platforms.

In my backend internship, I developed secure API endpoints using TypeScript, Express.js, and Zod with 100% data validation compliance. I also optimized the Homework AI platform by refactoring backend services, improving scalability and reducing latency for user interactions.

As a Fullstack Developer Intern, I designed and deployed backend services for a shortlet management and booking system (PropKeys), integrated BullMQ for background jobs like email notifications, and automated reminders with cron jobs. I implement robust rate limiting and security middleware for high availability, and I collaborate cross-functionally with frontend developers and designers to ship MVP-ready features.
