Tech Stack: Java, Spring Boot, Apache Kafka, Docker, Kubernetes- Contributed significantly in the complete architecture, design, development of the software solution and infrastructure right from scratch.- Written framework for caching and failovers, designing micro-services, written rate limiter library, written Kafka based messaging library for asynchronous communication. These libraries are used by by all micro-services and same is running in production without any issues.- Developed framework to reliably make REST calls in distributed fault tolerant environment so that it is retried upon failure in a particular order.- Worked on Performance optimization of the product. The api’s which used to take 10-15 secs to process, optimized it to 100 milliseconds.
