Business4Business is a work market where companies interested in hiring software development teams and teams that are looking for projects in the same field meet.

Design of UI

We based the UI on Material Design. We also used the CSS framework Materialize for the implementation. This application is visually simple and easy to use.


This application was developed in Ruby on Rails. The user flow allows the registration of software development companies and companies interested in developing projects using technology.

We integrated with Stripe for payments.

The development team was conformed by 2 engineers working full time.

def fee_paid?
  payment = payments.last
  payment.nil? ? false : !payment.time_expired?
def user_has_paid?
  if current_company && !current_company.fee_paid?
    redirect_to pay_path and return

Our Process


We have weekly calls where we discuss progress. We use Skype, Google Hangouts or GotoMeeting.

We agreed on a day and time that worked for everyone.


In the beginning we send a timeline specifying the planning and tasks for that week.

These tasks are the same cards we have planned in Trello.


We translate all requirements into stories in Trello Cards.

Trello is the place to add any specification, ask questions or comments to the team.


Once the tasks are done they go through a testing process and we pass them for your approval.

Every week we will pass cards onto the client list for you to give us feedback.

Quality Assurance

Once the functionality is completed one of our functional testers will try to break the feature.

We either move it to Needs Improvement or pass it to you for feedback.


We need the support from you to review the cards and Approve them or tell us how to improve it.

This is key to meet goals and being on time in the development of the application.
