I'm from Portugal, and I'm developer at Hubstaff. Previously I worked on NDrive where i was responsible for develop and maintain microservices architecture.
Most of services were written in Ruby (using Rails API), because old architecture was rails monolithic stuff. With time ended up doing Ruby/Go/Python/C++ Microservices.
My biggest challenge until today was being founder of one startup called Outitude "Booking platform for outdoor activities", you can check some photos at my Portfolio.
Chef/Capistrano migrated to Ansible/Docker
Before that you can check my linkedin profile, over 9 years of experience.
If you want more information about me, just ask, i will be glad to explain
