Hire Pedro


My passion and professional work for more than 18 years have been all about graphics, applications with user interfaces and all related aspects (programming, UI Design and UX).

I have both programmed and created the UI Design of applications for my clients. I’ve worked for companies that are tech leaders, for world recognized fortune 500 companies and for small startups with small budgets that are now outperforming established software implemented with significantly higher resources.

Besides that, I've also worked for companies helping to develop the technologies that programmers use to implement the interfaces of their applications (e.g. helping to develop the official tools of JavaFX, etc).

In my free time, I like doing open source (FOSS). Some of those FOSS projects are used worldwide and in the most well-known Java software like famous NASA applications (Deep Space Trajectory Explorer, etc) and applications used by the USA's White House.
