- Worked with breaking down monolith application and rewrite in multiple microservices focusing on Scalability, Availability, Data Resilience, Security & Observability. Technology used: Spring Boot, MinIO Object Storage, Apache Pulsar, Aerospike(distributed caching), Prometheus etc. - Worked heavily configuring and integrating microservices with Kubernetes and Helm. Work includes: containerized applications with Docker, configure and deploy the application to multiple environments, HTTPS and certificate configuration and management automation. - Facilitate services to be production-ready by finding performance bottleneck on serving requests, thread pool optimization, setting up logging level dynamically etc. Used profiling tools like VisualVM, JDK Mission Control and optimized code to make application faster.
