Bhaskar Purohit

I’m a backend engineer specializing in serverless architectures and event-driven systems on AWS. I’ve spent 4+ years delivering production GraphQL APIs and Node.js services at Deloitte (HashedIn) and Capgemini, and I’m currently building AI-integrated backend tooling.

At HashedIn by Deloitte, I designed and owned backend workflows where Salesforce-triggered events drove AWS Lambda async processing for trade certification pipelines, including DLQ-based error recovery and CloudWatch observability. I built serverless services with Node.js, Lambda, and GraphQL for live traffic—handling orchestration, input validation, and structured error handling across distributed components.

I also focus heavily on performance and reliability: I reduced P95 query latency by ~60% using schema normalization, partitioning, and index optimization, and I diagnosed Lambda cold-start cascades plus DB connection pool exhaustion with CloudWatch logs and runbooks. Earlier, at Capgemini and DesignBytes, I shipped backend APIs and caching/performance improvements (e.g., Redis reducing DB round-trips ~40% and faster wallet queries) while partnering cross-functionally on frontend/auth experiences for product teams.
