    With over 20 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. Skills: * Information Architecture (IA) * Domain Driven Design (DDD) * Object Oriented Design (OOD) * Object-Relational Mapping (ORM) * Object Oriented Programming (OOP) * SaaS development * Test Driven Design (TDD) * Unified Modeling Language (UML) * Unit Testing * User Experience (UX) * User Interface (UI) APIs: * Google Calendar * Google Maps * OpenAI Frameworks: * Vaadin 7, 8, 10, 13, 14, 23 * Spring Boot * Spring Security * JPA * Hibernate - ORM tool * Flowable - BPM tool * Quartz Scheduler * Rulebook * JUnit * mockito * vavr.io - functional programming for Java * Blaze-Persistence * OpenAI-Java Tools: * Intellij IDE * GitHub * Bitbucket * Jira * Confluence * PlantUML - UML diagramming tool * DBeaver - Universal Database Manager

    I have been an entrepreneur all my adult life. Originally i was a self-taught database programmer and branched out from there. I founded 3 tech firms that started from zero and the largest grew to over 400 employees. I sold them and scaled back to a one-man operation. I have substantial experience with WordPress, HTML, CSS, .... And MERN, MEAN, Django/Python and the native & hybrid app development also. I have learned software engineering "in the trenches" by self-study, mentoring under other programmers and engineers and taking various technical courses over the years. I got into software engineering originally in the early 1980's because software didn't exist for the business I was running. So I taught myself to be a database programmer and wrote my own. "The rest is history" as they say. I can handle a variety of projects both large and small. I'm sure you will be happy with my work!

At A Glance: Vaadin Framework

One of a seemingly endless array of choices for developing high-tech business solutions on the Internet, Vaadin is a web application framework for rich Internet applications, and it features server-side architecture that reduces the burden on processing power in personal machines by moving the demand to Vaadin servers. Vaadin Framework utilizes the Java programming language to streamline the process of creating installable web applications and dynamic web content, and as an Apache-led open-source project, it has developed a sizable global following for support and enhancement.

Utilizing a freelance Vaadin Framework expert for a project undertaking the challenge of creating a single-page web app or leveraging Vaadin enterprise web components gives you access to this powerful web application framework in addition to a highly skilled computer programming professional. Vaadin Framework developers and programmers are capable of working on two fronts: helping develop or modify programs running on Vaadin as well as maintaining the servers upon which applications roll out their updates and changes. Through event-driven programming, these knowledgeable developers and programmers take advantage of a more graphical style of programming, which in turn gives you and your business access to a simpler and more visual development process for your web application needs. Implementation of Vaadin through those expert developers and programmers is a powerful way to tailor useful web applications to your business’ particular requirements. Browse the listings of relevant Vaadin Framework developers and programmers on Upwork to find the one who best combines everything you’re looking for.
