Summary
🤩
Rockstar🎓
Top SchoolPhil Calçado is a seasoned technology leader and engineer with 17 years of experience building cloud-native platforms, microservices, and developer tooling across companies from Globo and SoundCloud to DigitalOcean, SeatGeek, and PicPay. He combines hands-on systems design—illustrated by founding Outropy and designing Linkerd 2's control plane and CLI—with executive leadership as a former Global CTO and senior director who drove large migrations, cost reductions, and product launches at scale. Phil has a strong open-source pedigree, contributing backend and DevOps improvements to high-profile projects like linkerd/linkerd2 and Twitter's Finatra, focused on reliability, testing, and observability. As a guest lecturer at PUC Rio and member of the New York CTO Club, he mentors engineers on distributed systems and microservices architecture while staying active in practitioner communities. Not obvious from titles alone: he repeatedly blends deep technical craft with org-level operational change—e.g., creating benchmarking frameworks for service meshes and cutting infrastructure spend by millions. Based in New York after a global career from Rio to Berlin, he excels at turning complex distributed problems into pragmatic, production-ready solutions.
