I am an experienced Java developer with expertise in Java, leveraging Java 8 features such as lambda expressions, the Stream API, and functional interfaces to build high-quality, scalable backend systems. I have developed and implemented custom software solutions for warehouse material handling systems, utilizing the Spring Framework (Spring Boot, Spring Batch) and Hibernate to create maintainable, performance-optimized applications. My experience includes building and maintaining RESTful APIs for seamless front-end and back-end communication, and utilizing Java Messaging Service (JMS) for asynchronous processing in real-time environments. I have integrated and optimized databases like Microsoft SQL Server and Oracle, and ensured smooth system performance using TCP/IP protocols. Additionally, I am proficient with tools such as Eclipse, Git, Maven, Jenkins, and Microsoft SQL Management Studio, and have worked with cloud platforms like Microsoft Azure/DevOps to scale applications effectively. My expertise extends to front-end development with JavaScript, HTML5, CSS, and Bootstrap, ensuring a responsive and user-friendly experience. I have successfully led Agile teams, conducted unit and integration testing, participated in code reviews, and ensured secure application development using JWT and OAuth. With a focus on modularity, reusability, and maintainability, I strive to deliver efficient and high-performance solutions while collaborating effectively with cross-functional teams to meet business requirements.

I have extensive experience in Java and JEE technologies, with a focus on using Java 8 features, developing UI modules with Angular, Node.js, React JS, and integrating RESTful APIs. I have architected and implemented microservices, developed CI/CD pipelines, and managed container orchestration with Docker and Kubernetes. My expertise includes working with AWS, Spring frameworks, and database systems like MySQL, PostgreSQL, Oracle, and MongoDB. I have also developed high-performance e-trading systems, designed scalable networking layers, and utilized Kafka for real-time data streaming. Additionally, I have implemented security measures, optimized Java TCP connections, and worked with various tools and technologies such as Git, Jenkins, Azure, and Terraform for efficient application development and deployment.

I have been actively involved in agile (SCRUM) software development, collaborating with team members, management, and clients. I prepared design documents using Microsoft VISIO and tested services with Soap UI, Postman, and ARC. I developed CI/CD and release management solutions with GIT, Jenkins, Maven, Docker, Artifactory, Kubernetes, Helm, and Amazon EKS, deploying microservices from development to production. I implemented and managed microservices containers with Docker and Kubernetes, deployed applications on Apache Tomcat, and utilized Spring Core Annotations for Dependency Injection and RESTful web services. I leveraged Spring Boot Actuator for monitoring and implemented scheduled tasks for automation. I integrated external APIs using Spring Rest Template, enforced code quality with Git, and deployed applications to Azure App Service. Additionally, I designed RESTful APIs with Express.js, managed various DBMS, developed components with AngularJS, and provided Git support. I created user-friendly web applications using Angular Reactive forms and developed RESTful web services with Java Servlets, JSON, JAX-WS, JAX-RS, Hibernate, and JPA, handling asynchronous AJAX requests.

I have implemented design patterns such as Business Delegate, DAO, DTO, Service Locator, Session Façade, View Helper, and Value Object across various modules. I developed Hibernate mapping files and configurations for database persistence and utilized the Java Persistence API (JPA). My work included creating UML Class Diagrams and Sequence Diagrams for design documentation. I extensively used ANT Builder for code building and implemented Daily Rolling Log with Log4j. I leveraged the Spring Framework for Dependency Injection and integrated it with Hibernate, using SVN as the version control system. I ensured successful code deployment to client servers following thorough testing. I implemented Spring Web Flow principles and Spring MVC architecture for the presentation tier and business layer. Additionally, I connected APIs using Angular.js $http service and have extensive experience developing web pages with technologies like HTML/HTML5, XML, DHTML, CSS/CSS3, SASS, LESS, JavaScript, React JS, Redux, Flex, Angular JS (1.X), JQuery, JSON, Node.js, AJAX, and Bootstrap.

I have been involved in various steps of the SDLC, including analysis, design, and development of systems, creating specifications with Use Cases, Class Diagrams, Sequence Diagrams, and Activity Diagrams using Rational Rose. I designed user interfaces with HTML, CSS, JavaScript, and JSPs and developed applications using the Spring Framework, leveraging the MVC architecture. I implemented Dependency Injection (IOC) and AOP in Spring for exception handling, and integrated Single Sign-On (SSO) and SAML authentication procedures. I utilized design patterns such as MVC, Business Delegate, DAO, Singleton, and Factory, and enhanced pagination performance with HTML Helper MVC Web Grid and jQuery, loading graphical data with JSON. I used SOAP web services for large XML data transmission and tested them with SOAP UI, and REST web services with REST Client. I developed applications using JSP, Struts, and MVC Architecture, utilized the Java Message Service (JMS) API for messaging, and extensively used Hibernate for data access and updates in the database.
