About Rohan Pareek

I build backend systems that scale — and increasingly, systems that think.Over 4+ years across product and consulting environments, I\'ve shipped production-grade infrastructure used by 1M+ users across 1300+ enterprise tenants. My most impactful work at Intelex Technologies involved designing a multi-channel notification microservice from scratch — handling push message delivery with per-tenant configurability, built on AWS SNS, SQS, Lambda, API Gateway, ECS, and DynamoDB.More recently, I\'ve been deep in AI infrastructure: building a RAG pipeline on AWS Bedrock (Titan embeddings + Claude Sonnet for inference) with OpenSearch as the vector store and Lambda for query orchestration — working with mixed structured/unstructured document sets at scale.What I work with:Node.js · TypeScript · AWS (Lambda, SNS, SQS, DynamoDB, Bedrock, OpenSearch) · PostgreSQL · MongoDB · Redis · Terraform · GitHub Actions · React.js · New Relic
