Summary
👤
SeniorWilliam Pereira is an engineering manager in New York with 11+ years of experience guiding teams across the full stack, now focused on frontend and microservice integration while still shipping code himself. He blends hands-on development—particularly in reactive programming, streaming, and dataflow concepts—with cross-team facilitation and pragmatic process improvements to reduce friction and accelerate delivery. His background ranges from campus-wide systems and identity integration to leading engineering at Radancy, where he influences backend architecture and UI direction alike. Known for maintaining active personal projects and staying current with trends, he fosters close relationships with product owners, scrum masters, and stakeholders to ensure systems are useful and profitable. An advocate for “state in motion,” he connects reactive UIs and backend streams (Rx, Kafka, actor/dataflow patterns) to create more cohesive, real-time experiences.
