About

Full stack developer with Vaadin, Spring Boot

With over 40 years experience in full life-cycle software development which includes analysis/design, coding, testing, implementation, support, and maintenance, I am able to work with you to implement your idea or solve your problem. I'm eager and able to learn new domains, methods, paradigms, and technologies. You'll find me to be a team player with a can do and will do attitude.

My latest review speaks for itself,
"Paul did an outstanding job ... Superb work, timely, honest, knowledgeable, went above and beyond. Paul is meticulous in his approach. His work included helping specify the requirements, designing the solution, building and testing the software, fixing bugs and helping us deploy the solution. He was primarily focused in the areas of security (Spring), user management, UI development, persistence (hibernate), and exporting our data model to MS Excel. Paul was very fair in the accounting of his time. He was on time with all of his work. I'll likely engage him again without a doubt if/when needed."

If you are looking to build a web site and phone apps, you should consider building a Progressive Web Application (PWA) web site which will allow you to develop a single code base that can be "installed" on a smart phone to look like a native app.
