Charter-Rent Application


About the client

The owners of Fretamais have 25+ years of experience in the Brazilian bus-transport market. After joining forces with deÔnibus, one of the most significant bus tickets online portals of the country, they saw the unique market opportunity to mix their expertise in the transport industry and online marketing. One piece of the puzzle was missing still: a development partner.





Scope of work

  • Prototype
  • Web development
  • Payment integration
  • Product design
  • MVP

The challenge

Fretamais wanted to create a smooth and enjoyable buying experience for anyone who requires renting a bus with a driver. When we joined the project, the scope was still not so clear. Our product designers had a great time going through the user-flow!

With a slick design and only most-essential features, we wanted to make the navigation and purchase process as simple as possible. On the other hand, we've built additional manager-level panels that focus on increasing sales rate and profit margin. An extra challenge was to gather all requirements from a different continent and align the work throughout a relevant time zone difference.

The solution

After a few iterations of prototypes and cutting down distracting functionalities, we've found pinpoints that our application needed to cover. By connecting buyers and sellers, the goal was to build a marketplace that the client can manage in a semi-automated way. Settling the ground was fast and secure as we were adding blocks compacted in modules that let us work in a full agile manner. Including our colleagues from different teams helped to make the right decisions so we could keep pace and deliver implementation before the deadline.

Experimenting, fast iterations, and smart technology choices instead of tons of documents and too-long meetings.


The MVP was a fast working web application that includes a variety of complex calculations behind a simple user interface. The responsive and stable solution gives us space for future development and integrations.

from any device

We design our products in mobile-first approach when necessary, so end-customer can enjoy seamless experience across all popular devices.

When working on the project we focused on using the most recent technology pieces.

Fretamais relied on our recommendations and was not disappointed. We needed a scalable solution that is easy to implement and evolve with a growing number of users. Our technology stack was:

  • Node.js
  • Postgres
  • REST/GraphQL
  • JavaScript
  • Typescript
  • Docker

  • CircleCI
  • React.js
  • MobX
  • Jest
  • Socket.IO
  • Heroku

At every stage of the project, we kept transparency and clear communication. With structured plans and visible progress, our core team could see how we are doing at every step. That gave us a field for idea exchange and helped move forward across difficulties.
