What I'm looking for

I'm looking to build scalable, event-driven backend systems, contribute to strong architecture and engineering practices, and work with teams solving high-volume technical challenges.

I've built core systems for Celcoin's Client Dashboard, supporting high-volume financial interactions, cashouts, and consolidated reporting. I also architected a centralized Keycloak and Laravel authentication dashboard to strengthen security compliance across products.

At Box Delivery (Rappi Brasil), I evolved logistics systems that process high-volume daily tracking events. I built resilient Apache Kafka pipelines for real-time delivery tracking and high-performance REST APIs for critical services and external partners.

As Software Engineer and Tech Lead at Dynamic System & Vish!, I helped develop and maintain Brazil's national property registration platform. I led onboarding, code reviews, and architecture decisions while building APIs and geoprocessing routines for massive geospatial datasets.

My background spans PHP/Laravel, Node.js, TypeScript, event-driven architecture, databases, testing, and DevOps. I use Clean Architecture, DDD, design patterns, and TDD to make systems more maintainable, observable, and reliable.
