Nubank

In my current job, my mission is to support the expansion of offered products for new customers by both enriching their experience as well as, behind the scenes, create an environment where services are both reliable, stable and repeatable across the board, helping the company drive globalization by influencing global platforms on how they achieve plaformization

Staff Software Engineer - Customer Growth for Colombia

With the sunset of the Globalization team, moved to a team within Fraud that had within its scope defenses for Credit and Debit cards, First Party (internal fraudsters), Acquirer and Fake and other Identity related checks.

My job was evolving the system design to be more platformized, enhancing both its stability and cost efficiency by introducing Strong Domain design concepts as the key driver and revisiting architecture assumptions such as database engine, data retention and scaling choices as some of the tools. Key results were a reduction of almost 35% of crashes when comparing 2023 to 2024, fitting costs to the design by cutting down the unnecessary by more than 150K USD a year. In addition, influenced customer business units to reduce crashes by revisiting assumptions in their designs

Staff Software Engineer - Fraud

Joined Nubank with the mission of driving the company towards internationalization. My job was identifying major blockers that could hinder its global scale. Among the identified challenges, there were cross-unit collaboration and architecture prototypes. 

For the first, introduced a collaborative-based company wide Architecture Review mechanism for more tenured Engineers help reviewing software architectures from other units, sharing their know-how and experience while strengthening designs throughout the company. In addition, coordinated a company-wide Architecture Forum that also fostered collaboration by showcasing business and technical challenges to all company members, later recognized as an escalation mechanism for handling complex/cross-unit challenges by the CTO at the time.

Finally, influenced and collaborated as part of a cross-unit initiative for identifying different software prototypes/architectures, which ultimately led the way to other forked initiatives that recognized the problem's complexity and urgency considering the company's desire to scale globally. Consequences were introducing a Strong Domain based design as a principle and developing ways for Engineers to map their systems to their business domains.
