👨‍💻 Software Engineering

Since 2007 I have been working in the IT industry. I started with technical support, webmaster (remember that word?) of some websites, and managing Linux servers. Then I went to web development, I've developed websites and apps using Stacks as:

  • LAMP (Linux, Apache, Mysql, and Php).
  • JOTL (Java, Oracle DB, Tomcat, and Linux).
And now I'm starting with MERN (Mongo, Express, React, and NodeJS), and JAM (Javascript, API's and markup). I have a background in SysAdmin, InfoSec, SEO, Analytics, Web Content, and other fields. Sometimes I do Freelancing Jobs at Upwork
