Lerian was born to give more freedom and autonomy to financial companies with its open source core banking. Today, the engineering team has about 14 people and, as it grew, a challenge became increasingly clear: slow code reviews and PRs piling up.

According to Luiz Barrile, SRE Specialist at Lerian, it was common for senior engineers to start the day with a stack of pending reviews. “We would spend hours on repetitive corrections — formatting, variable names, style guide details — and that consumed a huge amount of energy that could have been going into architecture or security,” he says. In the end, the team was spending over 100 hours a week just on this process.

Adopting Kodus changed that. As soon as a PR is opened, the team now gets instant feedback: inconsistencies are flagged right away, adjustments suggested, and recurring issues resolved before anyone has to step in. In just 3 months and 5 days using Kodus, review time dropped by more than 60% — from 100 hours to less than 40 hours per week  — and PRs that used to sit idle for up to a day are now reviewed in minutes. Senior engineers gained the space to focus on critical tasks, reducing production issues and strengthening the platform’s architecture.

In practice, Lerian regained the equivalent of two full-time developers in productive capacity, turning review cycles that once took days into a process of just minutes, freeing up time to speed up releases and reinforce the stability of the platform.
