Nexedu

Nexedu is a communication platform for schools. It brings together all the players in the educative community keeping students and guardians in the loop. Think of a communication notebook on your cell phone. Guardians and students are immediately notified about any event or news sent by schools. I architected and designed the whole platform, coaching junior developers to build a tool that today is used by more than 30 schools in Argentina.

Worked as part of a distributed team for building a video aggregator platform that allowed creators to deliver their content to multiple devices including mobiles and TVs and monetize it.

I took over the project for implementing new functionality required to allow non-registered customers to make payments through the platform and adding new use cases. I also migrated several main views to a single-page application with Angular.

Grunt RPM Plugin

https://github.com/gastonelhordoy/grunt-rpm
I needed to create RPM packages for some Node.js projects I was working on. At that time, Grunt was still quite popular, and I looked around its ecosystem, but I couldn't find anything that could help me. So after doing some research, I built a Grunt plugin to create RPM packages for distribution and installation.
