Summary
👤
Senior🎓
Top SchoolDoug Campos is a seasoned Software Engineering Manager with 15 years of experience building and leading teams that deliver scalable distributed systems and data-intensive platforms. Currently leading engineering at Shopify after a Staff Engineer tenure, he has driven multi-year refactors, inventory and bundles architecture, and platform initiatives like Server-Driven UI and Plus self-serve. He combines full‑stack fluency (Ruby on Rails, React/React Native, TypeScript) with systems languages (Rust, Go) and a track record migrating monoliths to microservices and high-throughput stream processing. His open‑source contributions span impactful low‑level work—from JRuby JVM integrations to Rust’s Polonius borrow checker—and signal deep competency in performance, correctness, and legacy integration. Comfortable across product and infra concerns, he’s equally at home mentoring engineers, shaping technical vision, and shipping production-critical systems. Based in Florida, he brings rare breadth: from embedded databases and HFT‑style event processing to mobile push and cloud monitoring.
