The value of CWI Software Engineering

Our trajectory with the Casas Bahia Group has already included deliveries on several fronts, both in e-commerce and in other systems.

The third largest retailer in Brazil in the revenue category (Ibevar Ranking – FIA) has CWI as a significant partner in Software Engineering. The Casas Bahia Group (formerly Via), which had revenue of R$30.9 billion in 2022, owns the brands Casas Bahia, Ponto (formerly Pontofrio),, Bartira, banQi, Rede Celer and ASAPLog.

Our trajectory with the group has already included deliveries on several fronts, both in e-commerce and other systems, as well as the evolution of technologies adopted by the company. Among the products of this partnership is the cart currently used on the company’s e-commerce platform, which was updated by the CWI team and one of the benefits was the reduction in the number of interactions to complete the purchase.

Nine journeys of partnership between CWI and Casas Bahia Group

CWI is proudly one of the Casas Bahia Group’s largest custom software delivery partners. This provides us with a space to suggest technologies and improvements and places us in areas such as planning, design, technical leadership, team management and agility processes.

This opportunity is only possible due to a very high level of engineering delivery within the company. Due to the trust that was built based on excellence delivery and credibility, visible in every line of code, in every intervention we make in meetings. It is clear that the Casas Bahia Group can count on CWI at any time.

CWI presence in different areas

Casas Bahia Group’s IT is broad and well-structured, which means we work on several different journeys. They are: Customer Success, Commercial Intelligence, Self-Service Purchase, Store, Logistics, Marketplace, Credit Services, Infrastructure and Operations & Security. CWI employees are even part of some of the leaders of these teams.

In 2020, the already solid partnership was strengthened, with an optimization of the synergy of objectives of the two companies. Since then, CWI has been intensifying contributions that go beyond software delivery, such as the culture delivery and the evolution of technologies within the group. We have grown in relevance, always focusing on engineering with direct support from established solutions.

Significant results on multiple IT fronts of action

Being part of so many journeys in the IT area of ​​the Casas Bahia Group, CWI has already delivered a large number of solutions for different contexts. In this article, we will present three of them: improving the cart on the e-commerce platform, evolving the order area and improving the pricing API.

A new cart for the three e-commerces

  • The cart area of ​​the platform that serves the Casas Bahia, Ponto and Extra e-commerces was the focus of an immersion by CWI to understand the system in use until then and understand the main points of friction. The navigation flow as a whole was mapped to understand the application context, bugs and possible discrepancies.
  • Based on this identification, the project sought to transform the user journey based on the perspective of strategic design. With CWI’s hybrid leadership with the Casas Bahia Group, the development involved analyzing the flow and conversion funnel, reviewing tagging, carrying out A/B and usability tests with end customers, structuring a style guide, evaluating competition , benchmarking and social research.
  • The front-end challenge was to create a solution with customizable points for the other teams and that respected the guide determined by the Design chapter. In the back-end, the technologies used were .NET Core and Kubernetes (K8s).

Evolution of My Orders

  • One of the projects on which CWI worked together with the group was the integration of data from orders placed in physical stores and e-commerce. Due to this involvement, we were invited to participate in a meeting that would address another initiative that concerned the My Orders screen.
  • Initially, the proposal was to operate with a predefined layout and integrate with an API that provided order status. We understood that there was no way and explained the reasons. The result was the development of a new front-end and integration with the  API of orders  in record time to be available for Black Friday. Since then, the My Requests squad, among other Customer Success teams, has been co-responsible for CWI.

Update to the pricing API exempted requests

  • At a certain point, a technological evolution was also necessary in the API that delivers prices to the Google feed. The complexity was big. After all, this API is involved in an extremely sensitive issue for not just one, but three e-commerces.
  • CWI faced the challenge and, with just a first stage that lasted three months, it reduced the requests that arrived via the API by 50%. Since then, improvements have been made continuously and today all price delivery is modernized.

Beyond software: sharing knowledge

CWI’s work at Casas Bahia Group is based on a proactive vision of the client’s business. We identify opportunities and present proposals that contribute to the evolution of the technologies used, the way we work and team management.

An example of this second sphere of activity is the creation of dojos by the CWI team in the group. Dojos are meetings for code exercises or short lectures given and prepared by the employees themselves, spontaneously.

This is one of the ways we put our slogan, “beyond software”, into practice. We share knowledge and seek to add improvements to the company’s development culture.
