Summary
🤩
Rockstar🎓
Top SchoolPedro Ruivo is a Principal Software Engineer with 14 years of experience building and hardening distributed systems, currently focused on Infinispan and Hot Rod protocol work and recently at IBM after a long tenure at Red Hat. He brings deep expertise in clustering, performance and backend reliability from contributions to high-profile open-source projects like Infinispan, JGroups (TOA protocol) and Keycloak. Pedro’s work spans core protocol features, non-blocking APIs and test automation, including adding Hot Rod server flags and client tests to ensure correct behavior at scale. He combines research roots (MSc from Instituto Superior Técnico and cloud-transaction research at INESC‑ID) with pragmatic engineering, frequently fixing edge-case bugs in consensus and messaging paths. Notably, he has improved distributed counters, caching integrations and ingress configurability—small changes that materially increase robustness in production clusters.
