Thejas.A

Worked on Java 17 and Spring Boot 3/Spring Framework 6 enterprise applications, building and enhancing microservices and REST APIs for Angular and external integrations. Implemented persistence with Spring Data JPA/Hibernate, developed and optimized database features using Oracle SQL and PL/SQL, and integrated SOAP services (WSDL/XML/JAXB). Built responsive UI with Angular 17, including SPA workflows with RxJS and Angular HttpClient, and implemented security using Spring Security. Delivered event-driven communication using Apache Kafka (producers/consumers) and messaging with JMS/ActiveMQ when required. Containerized services with Docker and supported deployments across AWS and PCF, while maintaining Jenkins CI/CD pipelines with Maven, Git/GitHub workflows, and unit/integration testing (JUnit 5/Mockito, Selenium, Jasmine/Karma). Supported production via log analysis (Splunk), static code analysis (SonarQube), and troubleshooting across runtime environments, including WebSphere Applicat

Worked on Java Full Stack development for enterprise applications across design, development, enhancement, testing, deployment, and production support. Built scalable Spring Boot 3 microservices and RESTful APIs, implemented persistence with Spring Data JPA/Hibernate, and optimized Oracle SQL/PLSQL. Developed frontend experiences using Angular 17 with reusable components and RxJS-based integrations, and secured services using Spring Security. Implemented event-driven communication with Apache Kafka (and JMS/ActiveMQ where required). Containerized services with Docker and supported deployments across AWS and PCF, maintained Jenkins CI/CD pipelines, and delivered unit/integration and UI automation testing using JUnit 5, Mockito, Jasmine/Karma, and Selenium. Used Splunk for monitoring/troubleshooting and SonarQube for code quality, while also supporting Spring Batch and cross-cutting concerns with Spring AOP.

Designed and enhanced enterprise applications using Java 17, Spring Boot 3.x, Spring Framework 6.x, Hibernate/JPA, and Oracle. Developed backend services and Spring Boot microservices using layered architecture, created and consumed REST APIs via API Gateway, and built responsive React 18 (TypeScript) UIs with React Router and reusable components. Implemented Redux Toolkit state management, integrated frontend with backend using Axios, and added robust request validation, exception handling, logging, and security using Spring Security with OAuth2/JWT and HTTPS/TLS. Built Kafka-based asynchronous event-driven communication, containerized services with Docker for AWS/Kubernetes deployments, and maintained Jenkins CI/CD pipelines with Maven/GitHub. Added automated testing (JUnit 5/Mockito and Jest/React Testing Library), used Postman for API testing, and leveraged SonarQube and Splunk for quality and production monitoring. Supported Agile/Scrum delivery and ongoing production support with
