Worked as part of team of programmers in development and maintenance of Object Oriented Mod Perl system dedicated to the tracking of factory-to-dealership automobile transportation. Daily use of Perl, SQL (IBM Informix and PostgreSQL), JavaScript, YUI, Ajax, HTML, CSS and PDF.

Prior to Cargotel, I had always been a free-lancer working on a per project basis.

These were my favorites, all single-handedly developed by me:

Transchryver System - 2003 ~ 2009

I designed, developed and maintained a Web based system (Perl, MySQL) to handle ALL the export operations of this big Dutch-Ecuadorian Cargo Company, including customer management, AirWay Bill generation, cargo reception/tracking, integration with airlines via IATA Protocol, etc.

Analyzer 1.0 - 2006

I created Analyzer 1.0, a Web Application that takes an uploaded music file in Standard MIDI file format, parses its note events, interprets its underlining chord progression and outputs a graphic analysis of the piece in Contemporary Jazz Harmony Notation.

MediaPoll 0.1 - 2007

For the 2007 Elections of the National Assembly of Ecuador, the Government mandated that all 414 candidates would use the same budget and that the contracting of airtime would be handled by a single advertisement agency that would warranty an identical reach and exposure of all candidates.

I was contracted by the advertisement agency that won the bid to come up with a solution for the challenge: 6,899 distinct, non-overlapping Time Grids had to be created, each one having identical efficiency as calculated by the sum of (num. of spots * audience of the time/day slot * rating of program). I created MediaPoll 0.1 in Perl to do the job. It was like solving a very big Sudoku.

Education

I first learned HTML in 1998 from a borrowed book out of need to promote a Rock Festival in Ecuador. I later chose Perl randomly from a list of primers I found in the Internet while looking for a "dynamic" language, as the trend dictated.

I was instantly hooked and ended up spending a small fortune in O’Reilly Books, which was the basis of my programming education. That, along with daily use and a lot of curiosity and experimenting, taught me the most valuable skill of all: I learned to learn.

Otherwise, my formal education is a musical one:

Berklee College of Music - Boston, MA. Professional Music Program with studies in Film Scoring, Electronic Music and Composition. 1987

The Recording Workshop - Chillicothe, OH. Diploma in Recording Engineering & Audio Production. 1985
