👤
Senior🎓
Top SchoolJon Zlotnik is a cryptographer-turned-CTO with eight years of hands-on experience designing and deploying enterprise cryptographic systems, PKI modernization, and cloud security across banks and startups. He co-founded Dara after leading blockchain research and protocol security roles, and has a track record of building automated certificate issuance, hardening multi-cloud Vault clusters, and integrating YubiKey-based passwordless solutions at scale. Comfortable in Python, Go, Java and cloud-native tooling (AWS, Kubernetes, Terraform), he blends applied research with production engineering to turn proofs-of-concept into secure, auditable services. Beyond engineering, he brings practical operational security experience from SOC work and threat hunting, and a knack for teaching—having led university labs and onboarding programs. An avid tinkerer, Jon channels the same curiosity into robotics, embedded systems, and even breeding discus fish, reflecting a methodical yet experimental approach to problem solving.
