* Designed and implemented scalable, event-driven microservices and gRPC APIs in Go and Java for device security and management, supporting Web platform features across 10M+ endpoints with sub-100ms response times (Go, Java, Kafka, Redis, AWS, Kubernetes, Docker, Terraform, GraphQL, PostgreSQL) * Integrated centralized logging, monitoring, and alerting via OpenTelemetry, Grafana, and Prometheus, cutting MTTR by 50%

Developed Go APIs for large-scale device migrations (5M+ devices), optimizing for performance and fault tolerance with Redis, Kubernetes, and AWS (S3, EC2) • Optimized MySQL queries, achieving a 70% reduction in query times and 50% faster API responses • Designed and exposed GraphQL APIs for customer-facing analytics dashboards, enabling flexible, self-serve access to metrics” • Collaborated with frontend teams to shape backend API contracts, improving data accessibility and reducing integration effort

• Designed and maintained CI/CD pipelines using Jenkins, GitHub Actions, and Terraform, automating software deployments and reducing deployment time • Optimized containerized microservices using Docker and Kubernetes auto-scaling strategies, improving reliability under variable workloads • Developed internal tooling to automate cloud resource monitoring and debugging using Python, Prometheus, and Grafana
