What I'm looking for

I'm looking for a full-time remote role where I can build useful products, solve real-world problems, and grow as a developer. I enjoy backend development, APIs, and performance optimization. I'd love to work with a supportive team where I can share ideas, take ownership, learn new technologies, and help other developers while building products that make a real impact.

At Zooper Technologies Pvt Ltd, I delivered a production employee transportation platform supporting 2,500+ users and 500+ daily ride operations. I built and maintained 100+ REST APIs using PHP, CodeIgniter, Node.js, TypeScript, NestJS, and MySQL.

I established modular NestJS and TypeScript services that improved maintainability and shortened feature development time by approximately 20%. I also optimized MySQL queries, indexes, joins, and database structure to reduce API response times by 25–40%.

I accelerated real-time data delivery with Redis caching, WebSockets, and Socket.IO, lowering update latency by approximately 50%. I automated 3,000+ daily asynchronous tasks through Redis and BullMQ pipelines.

I connected payment, messaging, calling, and notification services, and secured application workflows with authentication, authorization, RBAC, and VAPT remediation. I also guided junior developers through code reviews, debugging, mentoring, and onboarding.
