Renuka Devi

I’m a Senior & Lead Backend Engineer with 7+ years of experience architecting high-throughput distributed systems, scalable microservices, and modern cloud infrastructure for Fortune 500 enterprises, including American Express and Amazon. I drive system modernization initiatives—transforming legacy monoliths and mainframes into resilient, event-driven architectures that process 10M+ daily operations.

In my recent technical lead roles, I’ve led backend platform modernization focused on scalability and resiliency, defining system architecture, API contracts, and integration patterns while partnering with architects and product stakeholders. I’ve also scaled microservices to handle 10 million+ transactions per day with 99.99% availability, and optimized Elastic search to compress end-to-end API response time from ~6.0 seconds to sub-2 seconds. I improve operational excellence through CI/CD automation, integration testing frameworks, and strong observability using Grafana and Prometheus.

I combine engineering execution with architecture design, specializing in Go, Java, Kafka ecosystems, Kubernetes orchestration, and low-latency processing. Earlier, I engineered automated compliance and enforcement backend services at Amazon Selling Partner Services, modernized infrastructure using AWS CDK, and built decoupled solutions with DynamoDB, Amazon SQS, and Amazon SNS. I also delivered enterprise web platforms and microservices at Capgemini using Java, Spring Boot, and Hibernate, supported by Jenkins automation and Cloud Foundry to reduce code-to-production cycles.
