Created the build, deployment and configuration related scripts for Maven

Involved in SDLC Requirements gathering, Analysis, Design, Development and Testing of application by following AGILE methodology (SCRUM).Developed UI applications using front-end technologies like HTML5, JavaScript, CSS3 and pure CSS layouts and using AJAX frameworks: Node JS, Express JS, EJS, jQuery, Angular.Updated the legacy application by building new components with new features of Angular 8.Involved in building a single page and cross browser compatible web application using Angular-JS (Angular routing), and used Controllers, Filters, Services, Templates, Events and Injectors.Implemented thread safety using Lock API, Synchronization, Multi-threading.Developed application using Java 8 to implement its features like lambdas Expressions, Time API, Streams, functional interfaces, collectors, default methods, type interfaces, for each.Implemented Bean classes and configured in spring configuration file for Dependency Injection, Developed Controller Classes using Spring MVC, Spring AOP, Spring Boot, Spring Batch modules, handled security using Spring Security.Used spring core annotations for dependency Injection, Spring DI, and Spring MVC for RESTful APIs.Designed and developed Micro Services business components using Spring Boot.Implemented Spring Boot Micro Services to divide the application into various sub modules.Developed Micro Services to provide RESTful API utilizing Spring Boot with Spring MVC.Implemented Batch jobs to deal with Large number of chunks using Spring Batch Framework to execute the similar jobs simultaneously.

Demonstrated strong problem-solving skills to efficiently address challenges related to account opening, CLOS, and branch automation processes.Used GIT for Version Control of code for incremental development on day-to-day basis to maintain code history and integrated Git with Jenkins to support build automation and integrated with Jira to monitor the commits.Utilized Java 1.8 features, specifically Lambda expressions, to implement anonymous inline function calls using Functional Interfaces, contributing to enhanced code readability and conciseness in a professional context.Efficiently deployed and managed solutions on public cloud platforms, ensuring adherence to established Service Level Agreements (SLAs).Utilized POSTMAN to inspect responses from various APIs, and leveraged Swagger UI as a visual documentation tool for both back-end implementation and client-side consumption in a professional context.Configured WebLogic JDBC connection pools for integration with diverse databases, including Oracle, MySQL, MS SQL Server, MS Access, and DB2.

Designed services to store and retrieve user data using CouchDB and Postgres database.Developed Web clients for dispatching the requests from microservice.Involved in developing Behavior Driven Development (BDD) and unit test cases.Developed SPRING controllers for dispatching the requests.Configure beans in spring configuration file with Spring IOC, Spring AOP concepts.Developed SPRING validators and services for handing correct data to SPRING DAOs.Exposed SPRING MVC controllers as Rest web services and implemented SPRING security into the application.Involved in building applications using React JS by building re-usable UI ComponentsUsed SQL developer to write database queries.Used MAVEN as build tool.Working with React.js for creating interactive UI's using One-way data flow, Virtual DOM, JSXDeveloped Micro services architecture using Rest APIs, Spring Boot and pivotal cloud foundry.Used Java-J2EE patterns like Model View Controller (MVC), Business Delegate, Data Transfer Objects, Data Access Objects, factory patterns.Designed & developed the End Points (Controllers), Business Layer, DAO Layer using Hibernate and Spring

Contributed to Design, development of the product and contributed to all the phases of product developmentImplemented Spring Security using OAuth 2.0. for the login authentication using REST APIs.Developed services that use REST template and will retrieve data from the organization’s corporate directory called LDAP (Light Weight Directory Access Protocol).Used Spring reactive using project reactor framework to promote asynchronous and non-blocking calls in the application.Creation of MySQL Stored procedures and efficient queries in the Generic DAO layer.Used Jackson API for marshalling and unmarshalling of data in XML and JSON.Use of Multi-Threading with Executor framework and ScheduledExecutorService for scheduling the tasks for periodic execution for the creation of thread pool for parallel processing to attain execution of tasks in asynchronous mode and a faster response time.Log Back for the logging the output to the files and Google Stack Driver part of Google Cloud Platform.Implementation of adapters using Spring boot for the organization’s Ticketing System called LMOS (Loop Maintenance Operation System). The adapters are used to collaborate with the legacy systems to send and retrieve the data from the external REST client using HTTP headers.Tracked GCP (Google Cloud Platform) traffic for error-handling and troubleshooting scenarios.Closely worked with the GCP API team to understand the REST contract between FES and API team and architectural design patterns being followed (E.g. Strangler, Split-Traffic)Extensive use of java8 stream API and lambda expressions for a better performance of the API and avoid code redundancy.Used Spring Data Framework to use the features of Spring JDBC and Spring ORM classes like JDBC Template to perform the database operations by connecting to Data sources available.Developed services using JMS (Java Mailing Service) API to publish mail notifications upon success or failure when the backend processes are completed.
