Rafael Neris is a tech manager and hands-on engineering leader based in São Paulo with five years of focused experience building and operating transactional systems at PicPay. He blends deep PHP expertise (PHP 5/7, Laravel, Lumen, CakePHP) with modern cloud and observability tooling (AWS, Kubernetes, Kafka, Prometheus, Grafana) to improve traceability and integrity across microservices. A strong advocate of software design principles—OO, SOLID, DDD, Clean Code and Microservices patterns—he couples architectural rigor with pragmatic process improvements using Scrum, Kanban and ITIL. Rafael has a track record of refactoring legacy monoliths into domain-driven services and serving as a community ambassador for PHP practices within his organization. Colleagues rely on him to translate complex transactional requirements into auditable, testable solutions that scale.
