Confidential, Charlotte NC

Java Developer

Responsibilities:

• Built single page web applications following Agile/ Scrum development approach with Angular 6 as front-end, Spring Boot as backend, MySQL as database set up through AWS RDS and Hibernate as the object-relational mapping tool to build a time tracking module for the payroll management application.
• Converted a monolithic app to Microservices architecture using Spring Boot.
• Used Spring Transaction Management to manage transactions in the Service Layer.
• Deployed, Scaled, Configured, wrote manifest files for various Microservices in PCF.
• Designing and developing new REST-based microservices on Spring boot framework and deploying them on various environments of Pivotal Cloud Foundry (PCF).
• Expertise working with SOAP, REST, and Microservices using CXF, Jersey and Cloud Foundry.
• Used Rest Controller to create RESTful API calls.
• Designed and developed a user interface using Spring MVC.
• Secured the API’s by implementing OAuth 2.0 token-based authentication/authorization scheme using Spring Security.
• Developing API for usingAWS Lambdato manage the servers and run the code in theAWS.
• Used the AWS-CLI to suspend an AWSLambdafunction. Used AWS CLI to automate backups of ephemeral data-stores to S3 buckets, EBS.
• Extensively involved in the integration of the Front-End web interface with the Spring.
• Developed the application using Spring Framework that leverages classical MVC architecture, JSP, HTML, and CSS.
• Used spring config server for centralized configuration and Splunk for centralized logging.
• Used Postman to test RESTful API calls for HTTP requests such as GET and POST.
• Deployed the application using AWS EC2.

Confidential, St.luois MO

Java Developer

Responsibilities:

• Involved in analysis, design, and development of a funds transfer system as well as account summary system.
• Developed specs that include Use Cases, Class Diagrams, Sequence Diagrams and Activity Diagrams.
• Designed and developed the screens using JSP and AJAX which gained good performance improvement.
• Developed the application using Struts Framework that leverages classical Model View Layer.
• Used Eclipse for writing code for JSP 2, Servlets 2.4, Struts 2.1 and EJBs 2.1.
• Implemented persistence layer using Hibernate 3.0 that uses the POJOs to represent the persistence database tuples. These POJOs are serialized Java Classes that would not have the business processes.
• Used amazon web services (AWS) to provide a cloud computing platform.
• Performed operations using AWS services like EC2, Lambda, DynamoDB, S3, CloudWatch, SNS for various data engineering tasks.
• Deployed the Spring web services in AWS cloudusingDocker containersutilizing theDocker Swarmcluster.
• Implemented the application using MVC design patterns deployed on JBOSS application server.
• Developed JUnit test cases for all the modules.
• Used HQL (Hibernate Query Language) and criteria for database querying and retrieving the results.
• Used SVN for version controlling and branching the code.
• Log4j was used for application flow logging purposes. Application logs were used to analyze the code path while tracing the issues. Log4j was also used while debugging the code by adding debug directives.
• Finding the Memory Leaks and adjusting the JVM Heap Sizes and GC Parameters using JProfile.
• Strong experience in migrating all the JSP web pages to JSF which was hosted on JBoss.
• Assessed the application performance using JProfiler and fine-tuned the application performance.
