Worked on multiple Executive Compensation web applications, contributing across the full stack with a focus on performance, maintainability, and scalable deployments.

  • Designed and developed innovative applications using Spring Boot Microservices, Angular, ReactJS, and DB2, delivering features critical to executive compensation workflows.
  • Refactored and optimized legacy web application architecture, achieving a 50% performance improvement through asynchronous APIs, scheduled CronJobs, lazy loading, and API splitting.
  • Integrated applications into the IBM CIO CI/CD pipeline, deploying them via RedHat OpenShift containers and IBM Cloud Kubernetes clusters to ensure consistent, scalable delivery.
  • Actively participated in the Jumpstart innovation program, where I worked on the Automated Microservices project. This initiative tuned deployment parameters (CPU, memory, HPA/VPA) using Prometheus metrics to improve application efficiency.
  • Improved container orchestration and observability using monitoring tools and platform-native tuning mechanisms.
  • Implemented Horizontal Pod Autoscaling (HPA) to dynamically scale applications based on load, resulting in a 20% reduction in cloud infrastructure costs.
  • Conducted comprehensive performance benchmarking and load testing with Apache JMeter, identifying and resolving bottlenecks by optimizing database queries, thread pool configurations, and JVM settings.

Key Contributions:

  • Delivered robust, high-performance internal tools for executive management.
  • Reduced technical debt by modernizing application architecture.
  • Built intelligent microservice tuning solutions based on real-time metrics.
