Professional Summary:

Over 5+ years of experience in Analysis, Design, Development, Maintenance, and Implementing Enterprise, Web, and Client Server applications using JAVA/J2EE and Object-oriented technologies.

Extensive experience using Java, Spring, Struts, Hibernate, Web Services, RESTful, JSF, JDBC, JSP, Servlets, EJB, JMS, XML, PL/SQL, and Oracle.

Proficient in applying design patterns like MVC, Singleton, Session Facade, Service Locator, Visitor, Observer, Front Controller, and Data Access Object.

Experience in building cloud-native applications using AWS services like EC2, S3, Lambda, ECS, and EKS.

Proficient in developing Kafka-based applications using the Java programming language.

Solid understanding of ReactJS architecture, concepts, and best practices for building scalable and reusable components.

Angular is built using TypeScript, a superset of JavaScript that provides static typing and additional features. As a Java developer, TypeScript's static typing and object-oriented features should feel familiar and comfortable.

MongoDB stores data in flexible, JSON-like documents called BSON (Binary JSON). This document-oriented model allows for easy schema evolution and dynamic data structures, making it suitable for agile development and changing requirements.

Manual testing involves executing test cases manually without the use of any automation tools, Writing test cases based on requirements or specifications.

Automation testing a tool for behavior-driven development (BDD) that enables creating test cases in a human-readable format.

Jira can be used to manage testing activities, including test case management, defect tracking, and overall project visibility.

React is primarily a JavaScript library for building user interfaces. While Java and JavaScript are different languages, your experience in Java should provide you with a strong understanding of programming concepts, which will be beneficial when learning React.

Expertise in front-end development using HTML5, CSS3, jQuery, JavaScript, and Ajax.

Java developers often use Kafka in various use cases, such as real-time stream processing, event sourcing, data integration, and messaging systems. Kafka's scalability, fault tolerance, and high-performance characteristics make it a popular choice for building distributed and scalable applications using Java.

Autosys can be used to schedule jobs that fetch data from various sources and publish it to Kafka topics. This allows you to automate the process of ingesting data into Kafka.

The Java client API provides a set of classes and methods to interact with Kafka, including publishing messages, consuming messages, and managing Kafka's administrative tasks.

Good experience in web application servers, including Apache Tomcat, Web Sphere, and WebLogic.

Hands-on experience creating Web Services using SOAP, REST, and Service Oriented Architecture (SOA) concepts.

Strong experience planning and developing designs for Migrating to the AWS cloud.

Extensive development experience in IDEs like Eclipse, My Eclipse, and IntelliJ.

Hands-on experience with build tools like ANT and Maven and logging tools like Log4J.

Expertise in unit testing with JUnit.

Good Experience in software configuration management using GIT and SVN.

Experience with continuous integration and deployment using Jenkins and Docker.

Involved in Agile methodologies, daily scrum meetings, sprint planning, and experienced in onsite-offshore coordination.

Java/ J2EE Developer Oct 2021 - Present

Involved in all phases of the Software Development Lifecycle (SDLC) using agile development methodology.

Developed web-based applications using spring frameworks and modules such as Spring MVC, Dependency Injection, Spring Core, Spring JDBC, and Spring Security.

Used Spring, Hibernate module as an Object-relational mapping tool for backend operations over Oracle database.

Developed web applications using ReactJS and Java.

React is built with JavaScript, so having a good understanding of JavaScript fundamentals is crucial. Make sure you are comfortable with concepts like variables, data types, arrays, loops, functions, and object-oriented programming principles in JavaScript.

Used Microservice architecture with Spring Boot based services interacting through a REST and Apache Kafka message brokers and worked with Kafka Cluster.

Autosys allows you to define complex workflows involving multiple jobs and processes. You can create workflows that include Kafka-related tasks along with other job dependencies or actions, providing a centralized tool to manage and orchestrate your data processing pipelines.

Angular 8 continued to improve the integration with Angular Material, a UI component library that provides pre-designed and customizable UI elements. It offers a rich set of components, themes, and accessibility features.

MongoDB offers built-in support for horizontal scalability through sharding, allowing you to distribute data across multiple servers or clusters. It also provides replica sets for high availability and automatic failover in case of node failures.

Involved in writing Java API for Amazon Lambda to manage some of the AWS services.

Implemented Java/J2EE Design patterns like Business Delegate Data Transfer Object (DTO) and Data Access Object.

Developed and consumed Restful Web Services using media applications like JSON and XML.

Involved in designing and developing web pages using HTML5, CSS3, JavaScript, Jquery, and Ajax.
