Summary
👤
SeniorJohn Day is a Principal Infrastructure and DevSecOps Architect and founder with over two decades of hands-on experience delivering secure, hybrid and embedded infrastructure for commercial and government clients from Sacramento. As CEO of Sycronix he architects FIPS-compliant and disconnected military systems, secure embedded Linux deployments, and enterprise hybrid cloud platforms while advising on large-scale cloud cost optimization. He brings practical startup and enterprise chops—from pre-Series A engineering at DeepFactor to technical marketing and Kubernetes POCs at Cisco—bridging product, sales, and operations. Known for translating DoD-level security requirements into deployable DevOps pipelines, he also trains and mentors teams to adopt repeatable, auditable practices. A detail not often stated: he has directly led storage and cost analyses that produced seven-figure annual savings recommendations for large-scale S3 deployments. His blend of government-grade security experience and real-world cloud economics makes him adept at turning complex constraints into operational solutions.
