Ruby(2y 5m):
Developed a service focusing on the subscription process and user privileges. Established and structured unit tests, along with creating mock services and integration tests using Roda, Sequel, RabbitMQ, Docker, Redis, and PostgreSQL.
Throughout my backend development experience, I have predominantly employed a microservices architecture, opting for Roda, Rack, Puma, Sequel, and a custom framework instead of the Ruby on Rails framework. Presently, I am actively engaged in expanding my proficiency in Ruby on Rails.
Created integration tests on Ruby + Rspec and developed the architecture of unit tests for each microservice.
I want to grow in a responsible company with friendly colleagues, develop various software applications, improve my professional skills and learn new technologies
