Experience
- Application to Monitor Social Networks (Other amazing things)http://sonar.monteagudo.com.ar/
I developed, on my own, an entire application to monitor social networks like Instagram, Facebook, and Twitter. It has statistics about any public account needed and also sends messages/alarms to the client through a telegram if something important is happening.
It has a back end in R to download information, process it, and calculate statistics and a PHP front end to show the data. I also used C to manage sessions, create, delete and modify searches, and more.
