I took programming as hobbie with no degree or formal education related to this field. I am a Nutriologist aiming to employ web systems for all sort of automation, tracking health variables, and health promotion for both hospital environments and at the consulting room. I use Javascript, PHP, Google Apps Script, Node.js to build my systems, so far I have created internal systems for a school that consist of

Income system "Sistema de Ingresos", to generate payment invoices, and even sends SMS with a debriefing of all sold services of that day.

An administrative system for all goods purchased "Sistema de compras".

A small PWA to track Driver routes.

Other school small apps for teachers such as attendance list, etc.
