A collaboration with a small team to build and deploy a CRM application for a startup business based in Ohio.

User authentication application using Spring Security and Hibernate. Allows visitors and existing users to create new accounts, login to view pages which they have been granted access to according to their authority / access clearance, and logout. User passwords are encrypted and user login information is stored in a database (MySQL script included on GitHub). Features could easily be added or adapted to another application as well.

My goal was to explore Spring Security and Hibernate ORM and build a simple service, in a given timeframe, that could easily be added or adapted to future applications. This project also uses the updated component-based security configuration that is suggested by Spring's developers, in lieu of the now deprecated WebSecurityConfigurerAdapter.

Full-stack Java web application with server-side rendered user interface, built following specific user requirements. The application allows visitors to input and save data for locations, organizations, superheroes, their superpowers, and report the date, time and location of superhero sightings. Google Maps API for Javascript was implemented at the end of production to be able to display a dynamic map of the most recent reported sighting locations.

An entity relationship diagram and wireframes were built in the planning phase (included on GitHub). Superhero Sightings follows MVC design pattern and uses Spring Boot and ThymeLeaf to integrate the data model and the view layer, which consists of HTML template pages designed using both Bootstrap 5 and custom CSS.

Java console application for a fictional flooring business. Implements Spring for dependency injection and uses text files to store and manage data for the flooring business' past and upcoming projects. The assignment was to convert this console application to implement Spring for dependency injection. XML configuration was used to declare the dependencies to be managed by Spring IoC containers. The project follows MVC architecture, includes unit tests for all DAO classes and service layer classes, and uses custom exception handling classes.

Java application with graphical user interface built using Java Swing. Allows users to login as Employee or as Admin (if user has Admin access). Employees are able to view their own info, Admins are allowed access to view and edit other employees' info.

I originally wrote this in 2021 to teach myself SQL and work with JDBC after I heard about a small business that was attempting to move employee information from paper documents into a database.
