Hello, 👋 my name is Pedro Duque (Duke in English) Vieira, I’m a Software Engineer and Software Designer. I’ll start by telling you a little bit about myself…

I work as a JavaFX and Swing Freelancer and Consultant, but more generally can be described as a Front End Freelancer and Consultant since I also have experience in web technologies, building web apps, etc, and have experience in User Interface Design and User Experience.

My biggest purpose is to make user interfaces that people are happy to use and enjoy.

I have a Master degree in Computer Science, as a Computer Engineer I know all aspects of software (and hardware) development, including Front End and Back End development, I have also helped companies with key insights in the Back End development of their products but my greatest passion lies in Front End development or the development and design of User Interfaces. I’ve started to take great interest in User Interfaces during my final project of my Master’s degree, back then the iPhone wasn’t yet released and Design was still an afterthought for much of the software developers, product managers and company leaders. Actually, I realized even years before, the importance of Design, when a product manager told me that the users of their software thought the product was working much better when they made a new release and all that changed was the aesthetics of the program which were made better. Design is not just how it looks, and how it looks is just a fraction of good Design, still just improving upon this, contributed significantly towards a more positive perception of the qualities of the product.

After finishing my degree I’ve always opted to do software development in the area of interface design and development. I have worked professionally, building user interfaces in various technologies and basically on all platforms: web, desktop, cross-platform toolkits, native mobile, etc, since 2006. During that time, I have also been learning Design, by taking Design and User Experience courses and also through self-learning.

There is a reason why, big companies, leaders in the User Interface area like Google, Microsoft and Apple hire software engineers who also have deep knowledge in Design. Design is a fundamental aspect of great products, but unfortunately it is still sometimes disregarded. 

Since I started my own business I’ve worked for several companies worldwide, innovators and industry leaders, like for instance the most publicly known and award winner Gluon, who have made it possible to run a Java application, re-using the same code, on desktop and mobile by leveraging the JavaFX framework. I’ve worked with them for 1 year and a half, helping to build their cross-platform framework, working in Scene Builder, the GUI tool to create User Interfaces, building applications, etc.

My company Pixel Duke, is a software consultancy company specialized in Front End and User Interface development in various technologies.

On my spare time, I’ve made contributions to JFxtras – JXScene for JavaFX 1.2 and JavaFX 1.3 which allowed one to embed a JavaFX app in a Swing based app, this control wasn’t provided by Oracle at the time (it is now in the JavaFX SDK and goes by the name of JFXPanel). Back then my JXScene control was the only way to embed JavaFX in a Swing app, it was the only route if you wanted to progressively migrate an application from old Swing to the new JavaFX. Modellus, a free application used worldwide that I have been creating on my spare time (although I haven’t recently had time to), became the first application to use both Swing and JavaFX platforms together in a single application running side by side at the same time.

Other hobby projects include JMetro (a new JavaFX theme including skinning of JavaFX provided controls and addition of new controls) for JavaFX 2 and 8 and contributions to ControlsFX. Some other examples of contributions to the community are FXRibbonFXValidationFXCharts, etc. For a complete list visit the projects section.

Reach us with work proposals, whether you want experienced experts to take care of developing the whole user interface, including its design or you want developers that are better acquainted with Design, know how to best implement your design specifications and what’s important when doing it. There is usually a problem in software companies because Designers and Developers that need to work together don’t speak the same language. This ends up hurting the end product. Developers miss out on important concepts while implementing design specs and Designers are not aware of technical limitations that prevent the success of some design aspects of their mock-ups.

If you need extra assistance, I also have a couple other very experienced developers and creative people that can assist you.

I’ll guarantee to provide the best quality work for the best price you can get for that quality.

Feel free to contact us.
