I worked principally in system software, including support to operating systems (MCP) , terminal networks, database (DMS II) , using many different languages: Algol, Fortran, COBOL, NDL.
I implemented a system to digitalize signatures for the banking sector who start working online in 1987 and was the first integrated system implemented in a large bank in the country.

In this years I sell and install an enhanced digitalizing signatures system called VeriFirm, who was installed in a few banks in Ecuador and Colombia, also worked in signatures conversions for others banks.
1997- R&D
Recently I am trying to carry out a few projects presented in this site, this required learning a little of mechanics, metallurgy, chemistry and robotics.Education
Electronic engineering, Escuela Politécnica Nacional.
Programming languages
At some time I program in:
Assembly SL3/5, 80x86, 6502, 68000, 68HC11.
Algol, Applescript, Basic, C, COBOL, DCAlgol, EPL, Forth, Fortran, Hypertalk, Lisp, Modula-2, NDL, ObjC, Pascal, Perl, Prolog, Python, RPG, Scheme, Smalltalk, UPL, VRML, WebObjects.
In 1983 I wrote a Lisp interpreter in Algol, based in the book “Lisp” by Winston and Horn (first edition) , using this interpreter I run my first lisp programs.
