Shailaja ND

I’m a Senior Java Backend Engineer with 7+ years of experience building production-grade, high-availability backend systems for enterprise healthcare IoT and marketing technology platforms. Currently at HARMAN, I lead backend engineering for Philips RSG IoT platform as Senior Software Engineer — Product Development, architecting and delivering 12+ Spring Boot microservices that support secure remote connectivity, monitoring, diagnostics, telemetry, and device lifecycle management across 50,000+ customer healthcare facilities globally.

I specialize in Spring Boot ecosystem services (Spring Cloud Gateway, Spring Data JPA, Spring Security), microservices, and event-driven integrations with Apache Kafka/RabbitMQ, optimizing performance to sub-100ms baselines while maintaining 99.5%+ uptime across multi-region global deployments. I’ve led zero-downtime Cloud Foundry → AWS migrations using the Strangler Fig pattern with AWS DMS (CDC) and Lambda-based validation, and I engineer scalable REST APIs serving 50K+ requests/day with strong error handling, pagination, versioning, and OAuth2. I also build reliable delivery systems with Terraform, Kubernetes/EKS, Jenkins CI/CD, and observability (Grafana/Loki/Prometheus/CloudWatch), and I mentor junior engineers—raising test coverage from 45% to 90% and improving team velocity and ramp-up time.
