sergio

My name is Sergio Fernández (aka willy/wikier). I'm a Spanish software engineer, currently living in Salzburg (Austria), advocate of open technologies and thinkings.

Welcome to my personal web page!

As I said, I'm a Software Engineer, specialized on applied research. I focused my research on different aspects of Web Science, where I'm mainly interested about Web Architectures, Data Integration, Social Semantic Web and Linked Data. Beyond only writing scientifict papers, my motivation has been rather try to take the technology a step further. I worked in some applied research institutes around Europe: more than six years as research assistant at CTIC (Spain), for a few months in 2008 I was visiting DERI (Ireland), and in 2012 I moved to Austria for working as Senior Researcher at Salzburg Research. In these years I participated in large-scale European research projects as well as in W3C standarization groups. And now I'm assessing from my own startup, RedLink, how some of these research outcomes can actually work out there.

Since my time in college, I have always been passionate about open software technologies, free software or open source, way you prefer to call it. Long gone are the years of AsturLiNUX when we wanted to change the world from a modest LUG. But the same spirit has been with me these years where I developed several open source projects in collaboration with some organizations, such as the Apache Software Foundation.

Other of my passions is teaching, although I didn't want to pursue a professional career focused solely on this aspect. Whenever I have the chance I like to give talks or organize workshops. Eventually I also imparted some lectures at universities and private centers when required.

blog rss

Ocasionally I write in a blog those writing I find interesting to share. But I don't keep it as updated as I used to do, so you can refer to my twitter to get freshest information.

At BibSonomy you can find the same list, available in different formats (such as BibTeX, RDF and more). Google Scholar also gives you an idea of my papers and how are cited. Some day I'll upload all my presentations to Slideshare.

projects

Due my research activities, I participated in large-scale European research projects as well as in W3C standarization groups. But this list doesn't refer to those projects, but software projects I developed, of course pretty related with my research. You can check at ohloh some of my contributions to other open source projects.

current projects

Apache Marmotta
An Open Platform for Linked Data. At the end of 2012 we proposed to the ASF the incubation of this project based on part of LMF.
Apache Stanbol

The Linked Media Framework is a server application that bundles central Semantic Web technologies to offer some advanced services. I started to contribute this project in May 2012 when I joined the team at Salzburg Research.
RDFLib
RDFLib is a Python library for working with RDF. I contribute to it mainly with the development of the SPARQL Wrapper.
