Project Name: Bank OAO (Online Account Origination)

Brief description: This project aims to develop an online platform that helps users to effortlessly create a full suite of deposit products. The platform will offer a range of account options, including checking, savings, money market, certificate of deposit, and IRA accounts. The platform is developed on Amazon Web Services (AWS), powered by the combination of Spring Boot for backend services, React for the frontend, and RabbitMQ for efficient message queuing.

• Designed, developed, and maintained robust RESTful (JAX-RS) microservices utilizing various modules of the Spring Framework such as Spring IOC, Spring MVC, Spring Security, Spring Profiles and Spring Data, with a primary focus on Spring Boot, to facilitate seamless communication between frontend and backend components.
• Utilized Spring Boot features such as dependency injection, auto-configuration, and Spring Boot Starters to streamline application development and enhance maintainability.
• Integrated third-party RestAPIs and services, enhancing the functionality and feature set of existing applications.
• Used RabbitMQ to ensure reliable and asynchronous communication.
• Leveraged Redis to store and retrieve frequently accessed data, reducing the load on the primary database and improving overall system efficiency.
• Used Cucumber with Java for automated integration testing, creating and executing feature files with Gherkin syntax.
• Used Junit5 for compiling unit test cases.
• Utilized Mockito for effective unit testing by mocking dependencies, isolating components.
• Developed scalable and high-performance React components for the frontend, ensuring a responsive and engaging user interface.
• Integrated React functional components with Spring Boot RESTful APIs using axios, establishing efficient communication between the frontend and backend.
• Leveraged React Hooks, such as useState and useEffect, to create functional reusable components with improved readability, maintainability, and state management.
• Used Redux to manage the application's global state, facilitating streamlined communication between components and enhancing overall data consistency.
• Utilized AWS services such as EC2, S3, Cloudfront, ELB, Autoscaling groups to build and deploy applications.
• Leveraged existing CI/CD pipelines using Jenkins, automating the end-to-end process of building, testing, and deploying applications, resulting in efficient and reliable releases

• Created RESTful API (Using Spring MVC) which are further invoked from React as $HTTP service calls.
• Participated in developing authentication / authorization service (auth-api) for logging users into the website.
• Created ORM entities that map to the DB tables. Leveraged Hiberanate JPARepository functionalities such as JPA named queries, queries and spring transactions for managing data.
• Involved developing complex Stored Procedures, Scripts, Functions, Packages, Joins, Triggers and creating database Views.
• Used JIRA as a dashboard for project progress and to track performance metrics.
• Made the code reusable and eliminated redundant code by centralizing code that was being used by different sources.
• Enhanced application logging using Log4J2 and also improved projects over all sonar code coverage by including Junit test cases.
• Involved in deploying the application into QA testing and performance testing environments using Jenkins pipelines.
• Actively coordinated with testing team for identifying and fixing defects.
• Involved in creating change tickets i.e change management and coordinated deployments for the application.

Project Name: Programming Profit & Loss (PPL)

Brief description: PPL is a web application designed to fulfill business needs of the A&E Networks. It is used as a scheduling system to telecast programs in various tv channels at specific times with in the US network and other countries as well.

• Developed solutions for diverse programming scenarios in Java, employing Object Oriented Programming (OOP) concepts such as: encapsulation, inheritance, polymorphism, and abstraction.
• Used Spring JDBCTemplate as a DAO layer to retrieve data from Oracle DB and mapped the result sets using rowmappers.
• Created and maintained database objects like complex Stored Procedures, Triggers, Cursors and Views
• Written Junit test cases for the implemented functionalities and also mocked data using Mockito.
• Supported Operations team during the deployment and triaged production issues on regular basis.
• Used JIRA for project Planning and Testing and Quality Assurance as to create test cases and link them to related development issues.
