• Olá!
    My name is Diogo
    and this is a personal website.
  • Portugal is my homeland,
    but home is in Mainz, Germany.
  • I am an information systems engineer,
    although technology is overrated.


What is this website about?

this website


This website is a visit card and here I share personal information. The domain name preludiodigital.com was registered in 2003. It sounded good for a portfolio website and it has been living since then.


Diogo Roque Vieira Alexandre

That’s my full name. It is a long name in Germany, where I am now living. However, it has a common length in Portugal, where I come from!

  • Lisboa (Portugal) is a great city! It is probably one of the nicest cities in Europe. It is full of live, culture, good and affordable food, nice people, lays by the river and the sea. It was in Lisboa that I was born, studied and worked for the first years.

  • I have studied Information Systems and Computer Engineering in Instituto Superior Técnico da Universidade de Lisboa. Web development, user-centred design, usability and information systems engineering became a passion. Linux, web technologies, Java, Android and Eclipse are my favourite tools.

  • Following my sister steps, I went adventurous abroad to travel more and live a different routine. An unexpected opportunity came from Germany. I am currently still living a new experience and enjoying it. First in Darmstadt and now in Mainz I feel at home… although I am always ready for a little trip!

  • Enjoy the best in life! I take great pleasure in commuting every day by bicycle, travelling, having a beer with friends or even strangers, swimming, enjoying a Portuguese red wine during dinner, listening to music, dancing and hanging out. Far from home, I especially appreciate spending time with my family and good friends!

What I have developed an interest in...

Over 9 years experience in information systems engineering: requirements management, architecture design, user-centred design, usability and development. Skilled in a diversified range of languages and technologies, especially web technologies, Java, Android and databases. Very good in reasoning, project management, planning, organisation and sociability.
