R & D Intern in Technology

Jan 2020 – May 2020 · 4 mos · Pune/Pimpri-Chinchwad Area

Worked on an autoscaling project in Kubernetes by integrating custom Kafka lag metrics with the Horizontal Pod Autoscaler (HPA). Designed the system with one producer and multiple consumers, where scaling decisions were driven by consumer lag. Integrated metrics visualization in Grafana, enabling real-time monitoring and more efficient resource utilization. This project enhanced my knowledge of event-driven systems, observability, and cloud-native scaling strategies.
