He's also spent some time developing native Android apps and worked in various roles from leading small teams and being part of larger and distributed teams. For the past four years, remote work has taken 100% of his time. In his free time, Filipe organizes meetups and speaks at conferences.

Billing/Payment Services for a Ride

It was a payments service (we had a microservices architecture) where it was built in Ruby (not Rails) and communicated with other services through RabbitMQ. It was responsible for generating charges and reimbursing drivers in a specific way (private business detail) that would optimize costs (integrated with the Stripe API).
