I design and build scalable, cost-efficient backend systems using AWS serverless architecture.

With 9+ years of experience, I’ve developed cloud-native applications handling real-time events, high traffic, and complex workflows across healthcare and enterprise platforms.

I specialize in building event-driven systems using AWS services like Lambda, API Gateway, DynamoDB, EventBridge, and Kafka, ensuring high performance and low operational cost.

Whether you're building a new backend or optimizing an existing system, I can help you design a reliable and scalable architecture.

What I can help with: • AWS Lambda-based backend development • API Gateway & REST API design • Event-driven architecture (EventBridge, Kafka) • DynamoDB & NoSQL data modeling • System performance & cost optimization • CI/CD pipelines & deployment automation

Tech stack: AWS (Lambda, API Gateway, DynamoDB, S3, Cognito, EventBridge), Node.js, MongoDB, Kafka, Microservices

Let’s build a backend that scales effortlessly.
