Madeleine Muscari is a seasoned full-stack platform engineer with 12+ years of professional experience building resilient, high-throughput systems and API gateways at scale. Based in Berkeley, she blends hands-on technical leadership with product-focused infrastructure work—from designing global API ingress architectures and task schedulers to leading observability, finops, and platform teams. Madeleine has a track record of driving measurable impact (including multi-month cost savings and uptime SLAs at five-nines) and holds patents for global API architecture developed at Twilio. Comfortable in startups and large orgs alike, she has founded and scaled LLM-backed security tooling and now builds bespoke micro‑SaaS and agentic systems at Ontologi. A queer feminist hacker by ethos, she pairs rigorous systems thinking with a pragmatic, safety-first approach to ML and cloud engineering.
