about me


I am a creative and dynamic IT professional based in Braga, Portugal. I have a great passion for software development (Desktop/Web/Mobile) and MS Networks. I have good interpersonal and communication skills and I pride myself on being an effective team player that produces work to elevated standards. My work is a central part of my life, I love what I do. The challenge, the endless learning curve and the mission accomplished feeling, is what make me want for more.
I’m known for my love of out-of the office projects! I enjoy creating side projects outside of my working life, it's what keeps me updated with the latest trends and technologies.
Design and development are both creative pursuits, they are mutually inclusive, one couldn’t exist without the other. Having said that I enjoy coding and bringing data to life, which is why I wouldn’t classify myself as ‘ui designer’ but instead one that can bridge two philosophies and ways of thinking.

My work doesn’t end with the brief. Going beyond the parameters and models that have been set out is essential, not only for my own personal achievement and development but it reflects back in the final product.
I speak spanish, portuguese, english and basic chinese.
The reason why i think i can help you is that I never follow the If ain't broken, don't fix it, i believe there is always room for improvement.



what i do

Microsoft Platform

Visual Studio

Visual Studio

I'd had been using VS.Net for over: 12 years now. I started with version 2k2 "Rainier" all the way long up to this last release from July 2k15.

SQL Server

SQL Server

This is an intimate relation that started back in 2k and growth with the time. Today I design & build DBs in the latest versions including SQL 2k14.

ASP.Net

ASP.Net

With the internet boom, I started to develop professional web apps since 2k8, mainly for intranets, e-commerce and corporate websites.

Ajax

Ajax

Talk about any web platform without Ajax it's almost impossible. Ajax was a game changer since day one. I'd been working with client-side since 2k8 tied to ASP.Net.

VB.Net

VB.Net

This was (and still is) my first and favourite language since 1985.

C#

C# .Net

This is one of my latest acquisitions, just since the last two years that I had been working in C#, mainly because it's wide usage among companies.

MS Access

MS Access

This is one of those tools that I can call a true RAD. This was my gateway to learn Relational databases in '97. I like this tool so much that I have a website just for Access.

WCF

WCF

One of the so awaited technologies. I grabbed this one as soon as I could, even so, just in 2k14 I could seriously (ab)use in a massive project.
