Rex P is an Integration AI Engineer with ~4 years focused on deploying AI systems that behave reliably in production, backed by a long history in backend and platform engineering across startups and scale-ups. He blends engineering, data, and operational risk perspectives to surface what systems are actually doing before decisions are locked in, with practical experience building compliance-minded RAG systems and AI tools that cut FDA submission timelines dramatically. Rex has led engineering teams, founded an IoT ag-tech startup, and delivered high-throughput backend systems—work that included scaling a sensor pipeline processing 30GB/day and shipping sub-10ms ad-serving modules. He contributes to notable open-source security tooling such as Google’s OSV projects, adding Debian package enumeration, caching, and robustness features that improve vulnerability triage. Based in Modesto, CA, he prefers tackling the tradeoffs of AI adoption that don’t show up in demos and excels at turning ambiguous, high-risk requirements into auditable, production-grade systems.
