software craftsman

Hello !

Guillermo Álvarez

I am web developer and this is my bio


From the last year I am a happy spanish freelance. That let me work with geoposition systems (Maps) and mobile web apps (localStorage, JSON, html5 manifest), nosql CoudDB and ElasticSearch, Memcache, Javascript (by hand or with coffee).

I normally manage my own server (FreeBSD and Linux), currently I use CHEF, MUNIN and MONIT and if possible UPSTART, normally serverd with nginx and passenger.

I love Wireframes, Usability, User Experience, Grid Based Designs, and agile management systems (not necessary scrum or kanban).

In my spare time I am playing with Puredata, Mongrel2, ZMQ and learning Erlang.

Active member of the spanish ruby community, organizing this and last year Conferencia Rails, involved and occasionally speaker in madridrb.


I am a software/web/technology craftsman since 16. Start programing with basic, but .exe where cooler than .bas, so I move to C. The problem with that and 3d graphics, was the speed of the graphics.lib from borland compiler, so i learn enough x86 assambler to made my own libraries for 3d graphics with the int-10 of the MS-DOS system.

If you are curious, you always ask why something work, so the next logic step was electronics and robotics were I participate in few robotic contests.

I start the university (Politécnica de Madrid) in 2004 and leave a few years later after some good parties and a few honours because that was not the education I wanted for me. After the first year I start working with a control systems and automation equipment distributor as a technical and commercial employee, dealing with problems in airports, automated warehouses and factories researching for technical solutions to everyday problems.

In that company I also suscesfully migrate the management and accounting systems and the desktop environments to Open Source solutions like LTS or XEN.

By the 2008 I completely change my professional career to something more related with my principal hobby, so I start working with La coctelera maybe the first company in spain usign Ruby on Rails for production, and for sure, the biggest blog engine in Spain. I do the migration to GIT, the asyncroniusly image upload service based on Amazon EC2 with custom AMI, and the full text search engine with Sphinx

The next hop was Job And Talent the spanish recruitment social network were i worked on the candidate search function and dynamic generation pdf with help of groff unix command as a rails view format.
