• Successfully migrated Springboot microservices from Pivotal Cloud Foundry to Red Hat OpenShift, seamlessly integrating them into a modern Platform-as-a-Service architecture (PAAS).• Created microservices from scratch to implement business logic and on-boarded to OpenShift/PCF containers.• Implemented synchronous/asynchronous/parallel REST API calls using Web Client and Rest Template.• Configured end-to-end connectivity for multiple external partners by whitelisting certificates and managing diverse authentication methods and role-based authorization.• Onboarded 40+ API endpoints onto IBM's API Gateway Developer Portal, established TLS profiles for enhanced security, and set rate limits and quotas to manage service call volumes.• Implemented user session caching using Gemfire, achieving an 80% reduction in MongoDB load. • Resolved critical production bugs in high-traffic core applications, handling over 10,000 invocations per hour.• Boosted code coverage to 90% using JUnit and Mockito tests, verified through SonarQube.• Facilitated production deployments, ensured smooth service initialization, and monitored API availability using Splunk and AppDynamics• Mentored interns and newcomers, imparting domain expertise, architecture insights, and technical stack knowledge

North Goa

• Developed back-office application and microservices to store booking using Java Spring Boot.• Integrated and maintained pull requests from the team using Git.• Optimized Docker container for staging deployments, reducing overall time to execute by 60%• Created migration queries to manipulate data in relational database (Postgres).• Debugged API endpoints and live logs to solve production errors.• Developed and upheld a custom Selenium framework with Extent Reports for comprehensive E2E testing.

Bengaluru

• Added Java programs to map inputs from Frontend to Legacy systems through IIB nodes.• Converted monolithic legacy application to microservices using Java Spring Boot.• Achieved loose coupling through Service Oriented Architectural (SOA) pattern.• Addressed regular production bugs and improvements in existing applications that increased audience reach.• Reduced reporting API endpoint response times from several minutes to fewer than 10 seconds by rewriting the API, optimizing SQL queries, and adding a caching layer using Redis.• Deployed code to push logs to Paper trail and created instant email alert for production errors.
