Hello, my name is Pedro Duque Vieira. I’m a software engineer who is particularly interested in user interfaces/RIA. Recently I’ve started to venture as a freelancer.

I have a master degree in computer science. Have a 8 years experience building user Interfaces in various technologies and on that time I have also been self learning design.

As an hobby I’m currently developing “Modellus X” – http://modellus.co/, a free software for modelling physics and mathematics using javafx and swing.

Made contributions to JFxtras – JXScene for javafx1.2 and javafx1.3 and JMetro for javafx 2 and 8. Also some other hobby projects like FXCharts, FXValidation and FXRibbon.

My email contact, my twitter account and linkedin.

Feel free to contact me about work proposals/job offerings I’ll offer a price that’s unbeatable for a  very high quality work.

“Pedro is a tremendous software developer and an entusiast of great design. It puts everything on every project. You can see that he really loves what he does.
I have hired Pedro for remote developments also, with excelent results. He not only gets things done, he also suggests changes to improve the projects he works on.
I would recommend Pedro any time as a team member of a software development project remote or local.”
