Shivam Vashishtha

I’m a Senior Full-Stack/Backend engineer with 5+ years of experience designing and scaling real-time, cloud-native systems using Node.js, AWS, and WebSockets. I’ve delivered production-ready SaaS features and integrations across fintech and healthtech, building secure APIs, asynchronous pipelines, and high-throughput architectures.

Most recently, I build and evolve backend platforms such as a serverless Virtual CFO solution (AWS Lambda + SQS) for automated score computation, and I’ve implemented gRPC-based microservices, RAG/LLM integrations, and search/auth workflows. I also architect AI-driven experiences—like a RAG-based platform using vector embeddings—and lead real-time AI chat and IoT backends handling 10k+ concurrent WebSocket connections, while optimizing performance with Redis, caching, and robust testing.
