BoaCompra provides online payment solutions, mostly to the South American market, and its goal is to deliver single payment integration within these countries. Some of its partners include Valve, Riot, Electronic Arts, and Garena.

As a senior software engineer, I designed, developed, and maintained our highly available public and internal APIs and coached my teammates to achieve our goals together. We have a heterogeneous stack using Go, Node.js, PHP, MySQL, MongoDB, and Redis, all running in on-premise or cloud servers.
