- Helped to stabilize the Chivo Wallet in El Salvador. The App is handling close to 4million users, 150K requests/minute. - In 2012-2014 I built a system that collected data from electricity meters. An Android TVBox (bad choice but it did the work) was placed in the client facility (a Hospital and a Hotel), and the box extracted the data from the meter registers using the modbus protocol. Some meters had 2-bytes registers and others 4-bytes registers, some Big Endian and some Little Endian. All the data was sent to a Django backend every minute. We could see the energy consumption patterns by the minute. - Give a talk in PyCaribbean 2018 & 2019 — https://www.youtube.com/watch?v=74YwdVRTxvA - Help to migrate Goodbed.com from Python2 to Python3 and Django 1.8 to Django 1.11.
