What I'm looking for

I seek backend or platform roles where I can design scalable, secure payment systems, work with microservices on AWS, and contribute to observability and CI/CD in a collaborative, growth-focused team.

I am a backend engineer with 3+ years building high-throughput, compliance-grade payment systems using Python and Django. I design secure REST APIs, asynchronous task pipelines, and microservices on AWS to meet real-time transaction processing needs.

At White Light Solutions I architected Django microservices for 10+ banking partners, reduced bulk export time by 80%, cut asynchronous queue latency by 40%, and passed VAPT audits by hardening APIs. I also built a high-performance historical transaction server delivering sub-second p99 responses.

I have led backend integrations with UPI, NetBanking, and multiple bank APIs, implemented OAuth2/JWT security, and deployed scalable services on AWS. I deliver resilient, observable systems and automated CI/CD pipelines that support rapid, reliable production releases.
