What I'm looking for

I’m looking for a cloud-native backend role where I can build event-driven microservices and data pipelines, deliver with Terraform/Kubernetes, and lead with strong observability and automated testing to ensure dependable production systems.

I’m a result-driven Backend Engineer with 7.10+ years specializing in cloud-native architecture, event-driven data ingestion, and scalable microservices. I focus on building reliable systems that turn real-time and batch data into measurable customer value.

At Walmart, I work on backend platforms like the User Generated Content (UGC) and SmartCom notification workflows, processing verified purchase data to trigger personalized review requests. I design and deploy Spark-based ETL pipelines on GCP Dataproc, publish transformed results to Kafka for downstream consumption, and run services on Kubernetes/EKS with Terraform and Argo CD—supported by observability through Grafana and Splunk.

Across Syniverse and earlier roles at Deloitte India, ITC Infotech, and Fidelity Investments, I’ve architected secure, event-driven pipelines for messaging trust and mission-critical trading workloads. I also lead sprint planning and technical grooming for onshore/offshore teams, and I champion automated testing (Karate, Fitnesse, JUnit) and CI/CD practices to keep quality high.
