Warren Brasil

https://warren.com.br/
Warren is a fintech that provides automated investment services with the best-personalized portfolio to end customers through a chatbot and a fully-featured investment platform, offering possible suitable investments at low costs.

I also took on a leadership role by mentoring junior and mid-level developers through tech talks, code reviews, and chapter meetings. Additionally, I led the team in developing an in-house push notification service integrated with our platform and CRM.

I also focused on improving our technical quality and implementing CI/CD processes for more efficient and reliable software delivery. This effort helped streamline our development process and ensured our software was of the highest quality. As a result, I was offered a partnership with the company, indicating that my colleagues and superiors highly valued and respected my contributions to the product and team.

Justo | Justiceiro do Dinheiro

https://github.com/justo-justiceiro/justo-chatbot/
Justo is a Brazilian Portuguese chatbot that was developed from concept to MVP in a 34-hour hackathon.

The project aimed to teach financial education. Its starting content explains Brazilian bank standard products and simple tips for making better choices. We were selected to be mentored for six months to continue the project development. During the incubation period, the product was chosen to be internalized by the hackathon organizer.
