Project: Workforce Management System Description: The project aims to develop a workforce management system that includes a web application through which the workforce can mark their attendance, adjust work schedules, and many more. The system eliminates the requirement of the manual entry of attendance and leaves approvals thus making the system error-free and transparent. In the project, I worked on UI design and database development. • Participated in the whole Software Development Life Cycle (SDLC), including requirements analysis, front-end component design, server-side code development, testing, and implementation.• Experience in designing front-end components using HTML and CSS.• Participated in and gained an understanding of the back-end system development utilizing Spring, Hibernate, and Web Services.• Used MS Visio to construct sequence diagrams that show method interactions while adhering to the Agile approach and SCRUM sessions.• Participated in the development of the Service layers and the Spring MVC framework. The controllers and other beans, including Handler Mapping, View Resolver, etc., were configured.• Used SOAP-based Web Services to develop and consume web services.• Setup and implementation of MAVEN for CI Integration and Log4j for logging.• Created and implemented database operation in HQL using hibernate.• Used JUnit Framework to design and implement unit testing.• Created and extracted data from Oracle database using SQL queries, PL/SQL stored procedures, triggers, and packages.• Experience with AWS services like Lambda, S3, EC2, DynamoDB and Docker.

Project: Product Management tool Description: Product Management Tool helps product developers in managing product-related details like sales, updates in the product, defects, and potential risks related to the product. The tool helps in creating a datasheet of the product so that it can become easy to review the product. In the project, I have developed the SQL database that is used by the tool to store product history. • Participated in all phases of the SDLC for the project, including requirement gathering, analysis, design, development, and testing. This is done in accordance with the Agile and SCRUM process. • Experience in designing and developing app. modules, user interfaces, and JSP pages with HTML5, CSS3, JavaScript, Servlets, and Struts tags.• Used Collections Framework, Exception Handling, I/O System, Multi-Threading, JDBC, and Generics, among other fundamental Java concept, extensively.• Made use of Java 8 capabilities like Lambda expressions, resource classes, and database document fetching while writing code.• Used Stored Procedures and Spring JDBC to access the database.• Establish team techniques for DevOps, Agile, and the systems development life cycle (SDLC).• Experience in the implementation of functionality using Spring Boot, Micro Services, and Hibernate ORM. • Implemented the project structure based on the Spring MVC pattern and used a Microservices architecture with Spring Boot-based services.• Experience in designing an entire framework to support Test Driven Development (TDD) by making use of Dependency Injection for the software development process and to produce high-quality app.• Experience in optimizing Microservices using NodeJS and ES6 as interfaces to Cassandra NoSQL database.• Developed front-end applications using ReactJS, Flux, NodeJS, and Docker and Built Spring-based Java and Scala services to support Enterprise Web app.• Used Amazon Cloud Watch to monitor AWS services and Amazon Cloud Watch logs to monitor app.
