What I'm looking for

I seek a hands-on Full-Stack role building secure, scalable web and mobile products with a collaborative team, opportunities to lead features, and clear paths for technical growth.

I am a Full-Stack Developer specialized in the MERN stack, building both frontend and backend systems that scale for web and mobile. I have engineered real-time AI-powered platforms and multi-domain e-commerce apps with measurable user retention and reliability improvements.

At IQ TechMax I architected encrypted chat, voice, and video systems, integrated robust authentication and domain whitelisting, and deployed Node.js/Express backends with MongoDB that achieved 99.9% uptime. My work reduced manual support load by 70% and increased mobile user retention by 45% across deployments.

I focus on secure, API-first architectures, modular UI development, and faster delivery cycles—using React/React Native, Redux, Expo, and server-side templating when appropriate—and I continuously aim to deliver production-ready features that improve user experience and operational resilience.
