As a Java Full Stack Developer at Verizon in Irving, TX, my responsibilities include writing Java APIs for Amazon Lambda to manage various AWS services and designing applications using Spring MVC, Spring IOC, Spring transactions, Dependency Injection Spring Annotations, Spring AOP, and Spring container-managed transactions. I utilize Spring Kafka API calls to process messages seamlessly on Kafka Cluster setups and implement AWS solutions using EC2, S3, RDS, EBS, Elastic Load Balancer, and Auto Scaling groups, optimizing volumes and EC2 instances with Python. I am proficient in manually deploying built and Dockerized applications to ECS containers in AWS using Bamboo, writing Unit tests/Integration tests with JUnit, and employing Mockito for dependency mocking. My experience involves developing user interfaces and animations using JavaScript and Python, using CloudFormation Templates for AWS service creation, and implementing logging frameworks like Log4j for issue resolution during runtime. I excel in collaborating with Business Analysts to gather business requirements and presenting design and implementation plans using Java J2EE and cloud technologies. Additionally, I have a strong background in AWS server development, Docker container deployment, and API development for Serverless architectures using AWS Lambda. My expertise extends to container systems like Docker and container orchestration with EC2 container service and Kubernetes. I am well-versed in Angular 6/8 practices, creating Pipes, reusable Components, and Services. Furthermore, I contribute to the entire development cycle, reducing it by 40%, and have successfully created automated pipelines in AWS Code Pipeline for deploying Docker containers in AWS ECS using services like CloudFormation, Code Build, Code Deploy, S3, and Puppet. I am experienced in manipulating data with CRUD operations in MongoDB and handling database access using Node JS.

Specialized in developing and modifying SQL codes to meet client-specific requirements, utilizing computer application software. Implemented a Test-Driven Development approach and authored comprehensive test cases, resulting in a remarkable 40% reduction in defects and elevated code quality. Delegated the creation of applications using AngularJS, Node JS, Typescript, JSP, CSS3, and HTML5, while integrating tools such as jQuery, Bootstrap Struts, and JavaScript. Proficient in implementing Spring Boot-microservices for processing messages into Kafka cluster setups. Successfully improved a high-volume Java application, leading to a 10% increase in user engagement within the first month. Demonstrated expertise in selecting AWS services based on computing, data, and security requirements. Created Spring Boot-based Microservices apps for various stages and published Restful services using Spring MVC. Employed Angular JS to craft custom directives for data manipulations and standardized data display in the UI. Played a key role in the production deployment and monitoring of applications into AWS EC2, utilizing tools like Elastic Beanstalk, Lambda, Code Deploy, and CloudWatch. Proficient in version management using Git.

Collaborated with cross-functional teams to deliver 5+ complex Java applications using Agile methodologies. Designed Microservices-based applications with Spring, Spring Boot, Hibernate, and Gradle. Developed high-performance RESTful APIs and web applications using Java, Spring Boot, and PostgreSQL. Contributed to building a data center on AWS, installing SVN, GIT, and Jenkins images. Proficient in front-end development with HTML, CSS, jQuery, React JS, and Redux. Implemented MVC architecture using Spring MVC Framework and Spring dependency injection. Utilized Camel for Microservices integration and RabbitMQ messaging. Developed AWS Lambda APIs for Serverless architecture. Provided production support, addressing issues and contributing to building and deployment processes with ANT scripts. Implemented DevOps practices, including CI/CD, Infrastructure as Code, Monitoring, Logging, and Microservices.

As a Java Developer at Fidelity Investments, I developed web components and RESTful APIs using Java and Spring MVC, emphasizing modular and scalable architecture. I implemented Hibernate for seamless data persistence, utilized Spring framework features like Dependency Injection/IoC and AOP, and optimized DB2 database structures to align with Java-based solutions. I also did server-side validation, secure coding practices, and integration of CI/CD pipelines using Jenkins. I designed and developed a responsive GUI with JavaScript, HTML/HTML5, DOM, XHTML, AJAX, CSS3, and jQuery. Additionally, I implemented SOAP messages for secure web services communication. Collaborating with cross-functional teams, I used tools such as Jira and Confluence for effective project management and documentation.
