What I'm looking for

I'm looking to build secure, scalable backend systems, APIs, and microservices in a distributed or remote team, with opportunities to work on AWS deployments, payments, messaging, and production-grade platform architecture.

I've built production backend systems at XDBS Worldwide, including a Lead CRM for lead management, customer tracking, and research data sales. I integrated Razorpay payments, webhook processing, transaction reconciliation, and RabbitMQ-based bulk email processing to improve delivery reliability and reduce API latency.

Previously, I developed REST APIs for a vehicle inventory platform at DCDIUM Technology and built IVR call analytics services at Nextbridge IT Solutions. I work with Node.js, TypeScript, Express.js, MongoDB, AWS, and secure role-based access to ship well-documented backend systems.
