Profile: https://flows.cv/weifeng

Experienced software engineer and systems architect focused on building mission-critical infrastructure for autonomous and agentic systems. My work centers on governance, security, and enforcement layers that ensure AI systems operate safely, accountably, and within explicit constraints across digital and physical environments.

I’ve led and built distributed, cloud-native platforms across large organizations and early-stage startups, with a background spanning AWS, Apple, VMware, and security- and infrastructure-heavy teams. I specialize in defining system boundaries, failure modes, and policy-driven controls for high-risk systems operating at scale.

Currently, I’m building governance and security infrastructure to harness AI agents safely, emphasizing pre-execution controls, human-in-the-loop approvals, and auditability rather than model development or end-user tooling.

I’m most interested in problems where correctness, safety, and accountability matter more than speed or novelty.

Work authorization: U.S. Permanent Resident (no sponsorship required).
