Saulo Storel, Ruby on Rails developer

Ruby on Rails is my strong suit.

  has_many :projects         # => …
  has_one  :internship, -> { where(company: "FMS") }

    How I think request → response

    From request to response: each Rails layer with a single responsibility.

    1. GET /projects

      Browser

      The request reaches the server.

    2. config/routes.rb

      Routes

      resources :projects points to the right controller.

    3. ProjectsController#index

      Controller

      It only orchestrates. Dense business rules go to a service object.

    4. Project.includes(:tags)

      Model and PostgreSQL

      Queries with includes, no N+1, reusing scopes.

    5. index.html.erb

      View and Turbo

      Renders HTML; Turbo swaps only what changed.

    6. 200 OK

      Response

      Back to the browser, covered by specs.

    Systems Analysis and Development student, learning Rails hands-on and not pretending to know it all.

    I'm in the final term of my Systems Analysis and Development degree at Uninassau and work as a development intern at the Teresina Municipal Health Foundation. Day to day I work with Rails, PostgreSQL and Hotwire, open pull requests with tests and take part in code review.
