Opening Keynote – Obie Fernandez
summary
Zar builds a stable‑coin banking platform and survives a viral fraud wave that spikes signups from ~150/day to ~160,000 in one day (≈250k in a week) and absorbs a ~1000x traffic surge without downtime. The stack is React Native mobile backed by a 190k‑line Rails modular monolith (180 models, 10 engines). Three internal systems power automation: Nexus (RDF/Oxygraph) knowledge graph that fires events via Aventus event mesh with intention‑based subscriptions and generated Ruby/SQL filters, and Agora legates — ~47 autonomous agents, $25k/month token spend, Mattermost DMs, sandboxed code mode with allow‑list. Open‑source tools include Practis, Gravis, Service, Amounts, and a Machina Rails template.
