I start programming at 17 years, after learn COBOL programming with punched cards for IBM 360 y 370 computers; I get work in Secretaria de Turismo, and Sherwin Williams as COBOL programmer.
In 1999 I take the decision of work as independent developer or as we use now: “freelancer”.
In 2000 I created an administrative a POS System in MS Access 97 for “Casa del Libro” who are a books vendor with 9 stores in Mexico City, I was responsible of the implementation and adjustments to that system for about 4 years.
Also collaborate in different roles (all computers related) for HERESA, Angola Embassy, European Union Representation, PEMEX, CONADE, Banrural and others.
With all the experience I create a POS System named Datafox Punto de Venta) and sold this in Mercado Libre the first version was launched in 2007 and advanced to the version 6 that is the most recent. Also I created other solutions for Windows, Electronic Invoice System, Weight Control for Industrial, postal code software, POS for restaurants, and many other solutions.
Software for clients – Since 2012
In 2012, I begin to create software solutions for clients, some people want particular functions added to my POS System, for example public water payments, optical data, gun fire arms control, reservations for events, room management for hotels, and many others.
Apps for mobile devices – Since 2016
In 2016 to create apps in Android because some users need mobile apps. I created a POS System for vendors that have predesigned routes and the central needs to know every moment the sales made by the vendors. Also a laundry recollection system, a system for review the status of materials and inventory. All of this was made for Android Devices using Kotlin and Firebase. All are private apps for employees and owners not for general public.
