• Designed and developed highly scalable Java-based applications with Spring Boot and microservices, reducing page load times by 35% and improving user engagement. • Implemented API Gateway and AWS Lambda for serverless and Azure microservices, enabling on-demand scalability for application components. • Optimized S3 storage policies for efficient data access and reduced monthly storage costs by 15%. • Developed RESTful APIs using Spring Boot and Node.js, serving Angular-based web apps deployed via AWS EC2 and S3. • Develop REST APIs and backend logic using Java and Spring Boot. Integrate with DynamoDB for CRUD operations and querying. • Used AWS Lambda with Node.js for serverless functions, integrating with SQS, SNS, and DynamoDB. • Integrated RESTful APIs for seamless data exchange and collaborated with the front-end team to ensure smooth user experience. • Optimized database performance by creating efficient queries and indexes in MySQL, resulting in 25% faster response times. • Develop RESTful APIs using Spring Boot with Kotlin. Implement GraphQL APIs for optimized data fetching. • Java applications running in ECS can consume events from Amazon SQS, SNS, or Kafka (MSK), AWS Lambda can trigger ECS tasks for batch processing or background job execution. • ECS and ECR are essential for deploying Java applications in AWS. Java developers can build scalable, secure, and automated cloud-native applications by integrating these services with AWS Lambda, S3, RDS, DynamoDB, and App Mesh. • Designed CI/CD pipelines with Jenkins and Docker, automating deployments to AWS, and reducing time-to-market for new features. • Resolve backend issues in Spring Boot APIs and frontend issues in Angular/React. Troubleshoot application failures on EC2, ECS, or EKS. • Use an HTTP Trigger in Power Automate and Get the Flow URL after saving. • Write unit tests with Jest / React Testing Library. Perform end-to-end testing using Cypress / Playwright.

• Developed, tested, and supported Java/12FE web applications for over four years, delivering high-quality solutions that increased system performance by 40% and reduced customer-reported issues by 25%. • Designed and executed end-to-end testing strategies for Core Java applications, identifying and fixing critical bugs. resulting in a 25% reduction in post-deployment issues! • Containerized microservices and monolithic applications using Docker, deployed them via Kubernetes (GKE, AKS, EKS), and automated CI/CD pipelines with Jenkins, Cloud Build, and GitLab CI/CD. • Developed and implemented a performance tuning plan using Oracle SOL/PLSQL, optimizing database queries and reducing query execution time by 40%. • Use Amazon CloudWatch to monitor Spring Boot logs, JVM performance, and custom application metrics. • Implemented Jenkins to automate build processes, resulting in a 30% increase in development efficiency and saving an average of 20 hours per week. • Design and implement REST APIs or microservices using Java and Spring Boot. Integrate MongoDB as the primary data store. • Use Spring Data MongoDB or the native MongoDB Java driver for CRUD operations. • Deployed JAR, WAR, and JEE applications on JBoss server using Jenkins auto deployment. • Deploy Spring Boot microservices to ECS (Fargate), EC2, or EKS using CI/CD pipelines (Jenkins, AWS CodePipeline). Manage deployment rollbacks in case of production failures.

• Implemented user interface guidelines and standards throughout the development and maintenance of the website using DHTML, HTML5, CSS3, JavaScript, Ext JS, and jQuery UI. • Design continuous integration best practices for the development team using Docker, Ansible, and Jenkins. • Leverage Docker and Ansible playbook design for continuous deployment and continuous delivery, and maintain responsibility for configuration management for infrastructure as code. • Tested SOAP web services using SOAP UI and REST web services using REST Client. • Participate in project planning sessions with business analysts and team members to analyze business requirements and translate business requirements into working software. • Deployed the war files in JBoss 5.2 Server in Unix Environment. • Used jQuery to manipulate the DOM objects for a user interface look and feel, and for Ajax calls. • Involved in Code Coverage using Junit Test Cases, Mockito's, and Code Quality is done using SonarQube Analysis. • The external customer portal is developed using annotation-based Spring MVC and Hibernate. • Designed and developed end-to-end customer self-service module using annotation-based Spring MVC, Hibernate, and JSP. • Followed the Maven build life cycle to build the application and deployed it into the application server. • Design and implementation of Spring Security for the application for authentication process against LDAP. • Used Jira to track bugs, prioritize, and discuss the team's work in full context. • Wrote database queries using SQL and PL/SQL for accessing, manipulating, and updating the Oracle database.
