Experience as a Java Developer in analysis, design, implementation, integration, testing, and maintenance of applications using Java and Object-Oriented Client-Server technologies.Has exposure to the complete Software Development Life Cycle activities like User Requirement Specification, Requirement analysis, Design, Development, Unit testing (UNIT/Integration), Release and Technical documentation.Proficient in web application development using Java, JSP, Servlets, HTML5, CSS, and JavaScript and frameworks Angular, spring and hibernate.Well versed in using Software development methodologies like Agile Methodology, and Waterfall software development processes.Strong programming skills in designing and implementation of multi-tier applications using web-based technologies like Spring MVC and Spring Boot.Successfully led the migration of a large-scale Java application from an on-premises data center to AWS cloud infrastructureDeveloped application using Spring MVC, EJB, AJAX and Hibernate and SOAP/Rest web services on Presentation layer, the business layer is built using spring and the persistence layers uses Hibernate with Web logic Application Server.Designed and developed Microservices business components using Spring Boot.Used Spring Framework IOC (Inversion of Control) design patterns are used to have relationships between application components. Designed, developed, and maintained Extract, Transform, Load (ETL) processes to extract data from various sources, transform it into the desired format, and load it into the data warehouse. Utilized tools such as Apache Spark, Informatica to achieve efficient data integration.Automated continuous integration delivery workflows to deploy Microservices applications via Jenkins.Implemented data models and schemas to ensure efficient storage and retrieval of data within the data warehouse. Utilized dimensional modeling (e.g., star schema, snowflake schema) to support fast querying and reporting.Developed CI/CD system with Jenkins environment for build, Test and Deploy.Successfully integrated diverse data sources, including relational databases, APIs, JSON, XML, flat files, and cloud-based data storage solutions.Configured and scheduled ETL jobs using workflow management tools (e.g., Apache Airflow) to ensure timely execution and data freshness. Developed monitoring solutions to proactively detect and handle failures.Used Spring Boot for building Microservices and developed spring based application radically faster with very less configuration.
