Summary
Led performance engineering initiatives for cloud-native systems, optimizing application scalability, reliability, and cost efficiency across AWS and GCP environments.
Highlights
Architected and optimized high-performance, cloud-native systems across AWS and Google Cloud Platform (GCP), significantly improving throughput, resiliency, and cost efficiency through data-driven scaling.
Led Kubernetes performance optimization, fine-tuning container orchestration, HPA/VPA configurations, and resource quotas to achieve sub-second response times under multi-cluster workloads.
Engineered comprehensive performance optimization frameworks leveraging load simulation, JVM tuning (G1GC/ZGC for Java 17/21), and distributed tracing to diagnose and resolve production bottlenecks.
Optimized Apache Kafka clusters for high-throughput, low-latency event streaming, achieving very low publish latency and minimal consumer lag through broker, partition, and replication parameter tuning.
Developed automated performance testing ecosystems using NeoLoad, Apache JMeter, and K6, integrated into CI/CD pipelines (Jenkins) for continuous performance validation and built end-to-end observability platforms using Grafana, Prometheus, Loki, Sysdig, and New Relic.
