Working in one more application for the telecom sector, this time for TIM Brasil, I had a chance to apply my DevOps skills as DevOps leader influencing many aspects of the ERP system architecture. I also worked as a system architect on this project.

SUN is a project used by Vivo (Telefonica group) a big telecom company in Brazil to facilitate the process of making and treating new sales made by partners in the entire country. It is used by thousands of users having about 5000 requests per minute on average during peak times.

Worked in a multinational project called ISD with team members located in New York - United States, Curitiba - Brazil, London - England and Pune - India. ISD is the project responsible for delivering address, phone and currency localization features for all HSBC agencies and offices spread across the globe. All data changes had to be delivered in real time for all client systems through a central message broken. One of the changes that I did on the application was to control how many active sessions one user had on the system’s administration panel, not allowing them to have more than one active session at a time. I had to consider logins across the entire user base which involves branches in all the countries which HSBC had presence. I also worked on new features that involved events being delivered to the central message broker as well treating events coming from the queue. As a senior developer I was also responsible to help the junior developers on any difficulty they had and welcoming new developers on the team.
