Welcome to my personal website!

My name is Marco Meloni and I am a chemical engineer. I have been working for few years as a process engineer, one of the most beautiful and gratifying work, and in the past I have worked on the design of plants in the Oil & Gas, petrochemical and chemical sectors. Always passionate about information technology and new technologies, I decided to create a small personal website in which to collect and share ideas, tutorials, articles and calculation programs.

For this new version of the site, I opted for a minimalist layout, abandoning the still excellent CMS Joomla for WordPress.

I am also on Linkedin:
