What I'm looking for

I want to build secure backend services and microservices end-to-end—optimizing performance, reliability, and deployment speed on cloud, while owning features from design to delivery.

I’m a Back-End Engineer who designs and ships production systems—especially microservices on cloud—to improve customer experience and operational speed. At Air India, I designed and implemented “Evouchers” (NPS up by 20%), implemented in-app notifications using SSE and CDC, and migrated CrewApp from monolithic to microservices on Azure Kubernetes, cutting deployment time by 65%.

I also build secure, resilient services: I integrated Service bus and GraphQL for crew assignment roster sync, created REST API automation that increased “Workplace” posting by 35% in a day, and implemented IOCC design to create and email special occurrences. Earlier, I architected evoucher creation, storage, and mailing with OAuth and Stripe, restructured the codebase around SOLID to prevent SQL injections/CSRF/SSRF, and stabilized concurrency using pessimistic locking and session-based TTLs—while also delivering full-stack and front-end work using React.js and Node.js.
