Paolo Nigro
Freelance Web Application Developer / Developer at UniqueCollection - ILAM Foundation

Who is Paolo?

I am a costarrican web developer mainly dedicated to building applications on the Crossmarx development enviroment. I have been working on Museum and Collection Management, E-Commerce, Customer Loyalty and Administrative backend solutions for a variety of companies in the region.

I am the head developer for UniqueCollection Latin America, and work with the ILAM Foundation on the development of this solution. 

About CrossmarX

I worked for 10 years on web development with Joomla, Wordpress, and other Content Management Systems.

In 2014 I did a small internship at Crossmarx, to be able to assist in the development of the UniqueCollection Collection Management System.

I got to see how flexible, safe and comfortable it is to develop on the Crossmarx application engine, and decided to invest more of my time in learning how to develop my own applications, instead of using "out of the box" solutions which in the end lack flexibility and are difficult to maintain and keep secure.

Since then I dedicated myself to developing applications with CrossmarX, I have been working on Museum and Collection Management, E-Commerce, Customer Loyalty and Administrative backend solutions for a variety of companies.
