At KTO Group, I migrated the withdrawal flow from the monolith to a dedicated payments service as its sole implementer. I designed a gradual feature-flag rollout that reached a 99.4% success rate with zero post-deploy incidents.
I also integrated a Pix payment provider and, with another developer, built biometric-authenticated Pix transactions and the facial authentication flow required by Brazil's new betting regulation. As the sole developer for CPF-based player verification, I contributed to KTO Group being fully authorized under the regulation.
Before KTO Group, I developed software at Idealogic Software, including a seed-management platform and a solar proposal system. I focus on Java backend systems, event-driven architecture, and reliable payment flows, and work daily in English with distributed teams.
