At TELNA INDIA PVT. LTD., I design and maintain Node.js services and REST APIs for a global eSIM platform handling 10,000+ daily requests with 99.9% uptime. I reduced average API response latency by 20% through MongoDB query optimization, indexing, and validation improvements.
I develop APIs for subscriber onboarding, subscriptions, plan management, checkout, and eSIM provisioning. I also implement Redis caching and asynchronous workflows with AWS SQS.
For payment and checkout workflows, I integrate Stripe, Adyen, Apple Pay, Google Pay, and regional payment gateways. I use Datadog for monitoring, log analysis, performance tracking, and production troubleshooting.
Previously at ANUYAT PVT. LTD., I developed backend services and REST APIs across eSIM, CRM, project management, and PG management applications. I also contributed to a multi-tenant SaaS project management platform, working across backend and frontend features.
