Senior backend engineer building fault-tolerant IAM microservices and event-driven platforms at scale.
IndiaWhat I'm looking for
I’m a backend engineer with 8 years of experience building high-scale, fault-tolerant distributed systems at Dell Technologies and ThermoFisher Scientific. I focus on system design, high availability, and end-to-end platform ownership, with a track record of zero-downtime delivery.
At Dell, I’ve owned an internal IAM platform across 100+ enterprise applications, driving OAuth 2.0 token issuance and roles/permissions to achieve 99.9% uptime at peak load. I architected and maintained Spring Boot authentication/authorization microservices for the OAuth 2.0 Token Exchange flow, reducing token issuance error rates by ~40% and enabling 3× user growth without infra changes.
I enjoy modernizing platforms and improving operational reliability—migrating authentication services to new GitLab CI/CD with zero production downtime, automating OpenAPI spec generation, and leading Kubernetes (AWS EKS) operations with strong observability using Splunk. I’ve also modernized messaging from Spring Kafka to Spring Cloud Stream, strengthened secrets management with AWS Secrets Manager, and supported delivery through Agile/Scrum technical design and code reviews.
