Paul Capestany is a founder and engineer with 14 years of experience blending neuroscience rigor with production-grade site reliability and cloud-native architecture. He’s an obsessive optimizer who moved from remyelination research to running SRE responsibilities at scale for fintech and consumer platforms, including sole SRE coverage at a crypto startup interfacing with banks and regulators. As a consultant he architected cloud-agnostic, security-first infrastructure with GPU enablement for AI workloads, and he now leads his own venture, Signet. Active in the cypherpunk ethos, he co-organized large Bitcoin technical meetups and carries that protocol-minded perspective into secure, auditable systems design. Based in San Juan, Puerto Rico, he pairs deep technical troubleshooting with product and organizational fluency across startups and research contexts.
