Building at scale while the plane was flying.
Conta Simples needed to rebuild its entire internet banking platform from scratch — without taking the product offline. The existing system couldn't scale with the company's growth, and critical payment failures were eroding user trust.
Compliance workflows were manual and time-consuming. Repetitive tasks consumed hours that could have been spent on higher-value work. At the same time, new user activation was underperforming — onboarding lacked the personalization needed to drive engagement.
The challenge wasn't just technical. Every feature had to balance regulatory compliance, user experience, and business impact. We needed to ship faster without compromising security or reliability.
