Blu (Digital Bank in Brazil)
• New billet API for multiple bank service The initial API was designed to interface with a specific bank in mind, this approach was a legacy code from the startup period for the company. When the company grew, multiple banks were used to place transactions and it was necessary to provide a more flexible and
smart mechanism to allow customers to perform the same transactions they were used to, but including multiple banks. This project made it possible to
increase the client base 6%.
• New API for PIX transactions in Brazil bank system A new kind of instant transaction was implemented along Brazil’s banking system during 2019-2020 years. The initial implementation for the company to include this kind of transaction was done by the squad I was working on. This team implemented a
new micro service, as others we already maintained, interfacing with a huge selection of micro services using Kafka message broker, for a Rails monolith as
the central piece of software. This project made it possible to increase the client base 11%
