WHO I AM

Available for opportunities

Nationality: Indian

Open to relocation worldwide

Currently based in Tempe, Arizona, USA — originally from Chennai, India — I work as an AI Software Engineer specializing in GenAI, agentic systems, and cloud-native modernization.

I deploy multi-agent Claude LLM pipelines on AWS Bedrock to transform legacy systems into scalable, AI-powered applications.

Expert in integrating AI/LLM APIs, building RAG pipelines, and engineering auto-scalable backends using GenAI microservices on AWS. Experienced across the AWS ecosystem — Bedrock, Lambda, S3, CloudFront, API Gateway, EC2, RDS, Redshift, and Terraform IaC for multi-account CI/CD deployments.

I use Claude Code as my daily bread for coding and development tasks — proficient across the full stack, from frontend frameworks like React and Angular to backend systems with Python, Node.js, and cloud-native architectures.
