I've built secure, production-ready web applications at Excelerate and NetProphets Cyberworks, including a student progress dashboard released across two production cycles and real-time chat components supporting 500+ simultaneous users.

I work across React.js, Node.js, Express.js, MongoDB, JWT, WebSockets, and REST APIs. My projects include Imagify, an AI image-generation platform using Together.ai and Cloudinary, and ChatSphere, a real-time chat app with abuse detection, authentication, and video calling.
