Some of the enterprise/web applications I have designed an/or created provided for customer/user registration, user/admin login, role based functionality, user profile, scheduling, route optimization, file upload/download, search functionality and reports.

The problem domain of a few of the various projects were:

• aircraft fractional (scheduling small business jet aircraft)

• medical billing

• appointment settingusing Google Maps API, Google calendar API, and Google email API

• construction estimation

• workplace efficiency

• product research from customer feedback

• drone delivery simulation

• I was the architect for most of the projects listed above.

Some of the major components of the technology stack I used for these projects are:

• Spring Boot (project management, security, etc.)

• Vaadin (GUI)

• JPA (ORM)

• Hibernate (ORM)

• mySQL, PostgreSQL, or MariaDB

• Jasper Studio (reports)

• Tomcat (web server)

• Junit (unit testing)

This is a full stack for web development. Vaadin Flow automatically serves the required resources for a PWA. Several of these projects required integration with 3rd party services such as Google maps, Google calender, Google email payment, x12 837 claim submission, etc.
