What I'm looking for

I’m looking for a fast-paced environment where I can leverage my frontend and full-stack skills to build high-quality, user-centric products, collaborate with cross-functional teams, and deliver measurable performance improvements.

I’m Stephen Olasunkanmi, a fullstack web developer with intermediate expertise building dynamic, responsive interfaces. I’ve developed web products with HTML, CSS, JavaScript, and React, focusing on user-centric experiences.

In my Backend Development Internship at CodeTech, I built high-performance backend systems using Node.js, Express, and MongoDB with integration support for frontend teams. I optimized database performance and designed RESTful APIs, while using Git and cloud deployment techniques to support scalable, efficient delivery. I also achieved project optimizations leading to 20% cost reduction and 25% improved operational efficiency.

One standout project is a Solidity-powered video conferencing web app with real-time features using WebRTC and Socket.IO. I used React for a responsive UI and Node.js with Express for backend services, including JWT-based authentication and low-latency streaming under high load with modern UI/UX practices.
