Rockstar🎓
Top SchoolHazel Guo is an experienced software engineer and angel investor based in San Francisco with a decade of experience building reliable infrastructure and product-facing systems. She’s shipped platform and infra features at Notion and Asana—leading SOC2 readiness efforts, migrations to ECS/EKS, and reliable deployment and webhook pipelines—while earlier work at Google and Microsoft honed her systems and numerical optimization skills. As a founder/CTO she raised seven-figure funding to build AI agents for data extraction and drove early revenue, and now invests in startups across AI and developer tooling. Notably, she often bridges product and infra domains, making third-party integrations testable in dev environments and turning messy legacy clouds into compliant, scalable platforms. Simple, pragmatic, and outcome-focused, she’s not open to full-time roles but actively supports high-potential founders and teams.
