About

I’m a Backend Developer with experience building scalable, production-ready systems using Python, Node.js, and AWS. Currently working at EXL, I’ve built APIs for loan onboarding and transaction handling, implemented serverless automation with Lambda, and integrated payment gateways like Tabapay — impacting 15K+ monthly transactions. I’ve also led development on omnichannel communication systems (voice, SMS, campaigns) using Amazon Connect, improving user experience and boosting client performance metrics. I hold a B.Tech from IIT Ropar and am passionate about backend systems, cloud architecture, and automation. I'm open to new opportunities as a Backend Developer, and I’m always eager to work in tech-first teams that value impact and innovation.
