Involved in SDLC Requirements gathering, Analysis, Design, Development, and Testing of applications developed using AGILE methodology. Involved in gathering requirements and analysis meetings with business analyst and end users. Worked on onboarding during clients into the system and making changes as per the client requests.Front-end development using HTML5, CSS3 and client-side validations performed using JavaScript. Used Angular Lifecycle hooks to the application for adding more functionality to components at phase of the component creation.Developed, enhanced and maintained a Spring Boot based microservices application.Used advanced core Java features such as Annotations, generics, multithreading etc. throughout the application for well-structured programming. Developed and supported Kafka integrations, including topics, producers, consumers and streaming applications.Configured Spark streaming to receive real time data from the Kafka and store the stream data to HDFS.Implemented asynchronous APIs for producing and consuming data from Kafka clusters, utilizing message queuing and stream processing concepts.Created a caching layer with memcache and a cache flush API to optimize application performance and scalability.Collaborated with colleagues to set up alerts and thresholds for new features, leveraging monitoring tools to proactively identify and address potential issues.

Worked in Agile software development, attended daily Scrum meetings, Sprint planning meeting and sprint retrospective and tracked the progress on Rally and defect tracking.Responsibilities included Troubleshoot various software application and connectivity issues using debugging process and coding techniques in Java programs. I have utilized Azure Kubernetes Service (AKS) to deploy managed Kubernetes clusters in Azure. I am well-versed in creating AKS clusters through the Azure portal, using the Azure CLI, and leveraging template-driven deployment options such as Resource Manager templates and terraform.I have utilized JavaScript, HTML5, CSS3, and JSP to design and implement user interfaces.My experience includes extensive work with core Java concepts such as multi-threading, exception handling, and object-oriented programming (OOP) principles.I contributed to the migration of a legacy application from Struts to a Spring-based architecture. Utilized Spring MVC and JDBC Template for object-relational mapping and creating POJOs from the database.I have hands-on experience in developing microservices with Spring Boot and Spring MVC, leveraging Apache Camel for integration with other microservices.Implemented OAuth2 functionality with Spring Security to secure REST APIs, handling authentication, authorization, and token generation/validation for REST clients.

Involved in entire Software Development Life Cycle (SDLC) of the project like Requirement gathering, Conceptual design, Analysis, Detail design, Development, System Testing, and User Acceptance.Worked in agile software development, attended daily scrum meetings, sprint planning meeting and sprint retrospective and tracked the progress on Rally and defect tracking.Actively participated in user story discussions and planning to analyze the level of effort on project specifications. Also involved in development and grooming of Project Backlog stories with business and technology partners.Designed and coded application components in an agile environment utilizing Test-Driven Development (TDD) approach. Designed the front-end applications, user interactive (UI) web pages using web technologies like HTML5, XHTML, and CSS3.

Developed the J2EE application based on the Service Oriented Architecture (SOA) by employing Web Services and other tools for data exchanges and updates. Developed the functionalities using Agile Methodology. Designed and implemented UI using HTML5, CSS3, JavaScript, EXT JS, AJAX, JQuery.Developed various generic JavaScript functions used for validations. Developed entire user interface using various Ext JS components like Form panels, Tab panels, View port and Editable grids. Worked in all the modules of the application which involved front-end presentation logic developed using Spring MVC, JSP, JSTL and JavaScript, Business objects developed using POJOs and data access layer using Hibernate framework. Created and injected Spring services, Spring controllers and DAOs to achieve dependency injection. Used DAO pattern to fetch data from database using Hibernate to carry out various database specific operations and avoided redundant database access statements and thus achieved decoupling and flexibility. Used JAX-RS (REST) for producing web services and involved in writing programs to consume the web services with Apache CXF framework.Implemented Apache Camel routes using Camel -Spring XML and Camel -Spring processor beans to achieve integration with other Enterprise systems. Database development required creation of new tables, PL/SQL stored procedures, functions, views, indexes and constraints, triggers and required SQL tuning to reduce the response time in the application. Focused on Test Driven Development; thereby creating detailed JUnit tests for every single piece of functionality before writing the functionality.

Involved in System Analysis and Design methodology as well as Object Oriented Design and development using OOAD methodology to capture and model business requirements. Responsible to enhance the UI using HTML, JavaScript, XML, JSP, CSS as per the requirements and providing the client side using jQuery validations.Implemented the Model View Control (MVC) structure using Spring. Used Express JS framework for the development of web application using Angular JS, DHTML and DOM scripting. Used Angular JS and NODE JS frameworks on analytics dashboard of the SOA services. Used Grid functionality like Grid filtering, Multiple Sorting, Grid Cell Editing, Grid Row Editing. Used Spring Core Annotations for Dependency Injection and used Apache Camel to integrate Spring framework. Used Hibernate as Persistence framework mapping the objects to table using Hibernate annotations.

Involved in Software Development Life Cycle (SDLC) of the project like Requirement gathering, Conceptual design, analysis, Detail design, Development, System Testing, and User Acceptance. Designed and developed all the user interfaces using HTML, CSS, JavaScript, JSP, Servlets and Spring framework.Defined and designed the layers and modules of the project using OOAD methodologies and standard J2EE design patterns & guidelines. Used AJAX for developing asynchronous web applications on client side.Developed the DAO layer using Hibernate and used caching system for real time performance.Developed Web Service provider methods (bottom-up approach) using WSDL, XML and SOAP for transferring data between the Applications. Configured Java Messaging Services (JMS) on Web Sphere Server using Eclipse IDE.
