I am a full stack developer since 1993, I started with modeling and optimization applications (C / C ++), and later I passed on management type applications (PostgreSQL with C ++ interface). Also, I tested the development of the software in other languages and environments such as javascript with qooxdoo framework, wxWidgets (C ++), Java - AndroidStudio classes (coupled with PostgreSQL). In postgreSQL I use plpgSQL frequently. At this moment I try to switch to WEB (Express + Angular + primeNg).
