Itaú is a leading private Bank Institution in Brazil.
Itaú rented for 7 years an audio-conferencing product called Alodb created by me.
The solution was composed by a specialized audio-conferencing hardware and software that allowed the creation of audio-conferencing rooms for up to 240 participants per server.
The development was mostly written in C++/Qt with some pieces developed in Asp.Net. All using PostgreSQL as database.
It was a mission critical project with more than 99% availability, since they had used it as the main communication between Itaú’s offices around the world.
