YC S11 · team ?
Jose is an exceptional fullstack engineer with proven expertise building production omni-channel messaging systems (Addie's multi-channel voice/SMS/WhatsApp platform), real-time infrastructure, and scalable backend systems. His experience shipping communication products at scale, combined with strong TypeScript/Python, FastAPI, Next.js, and infrastructure skills, directly maps to OneSignal's Journeys team needs. The primary gap is lack of explicit experience with customer journey orchestration platforms or marketing automation, though his LangGraph agent work demonstrates sophisticated workflow/state management capabilities.
Hook: Your real-time omni-channel voice platform at Addie proves you can architect and ship the reliable, scalable messaging infrastructure that powers customer journeys at scale.
Missing: Customer journey orchestration platform experience, Marketing automation domain knowledge, Explicit A/B testing or experimentation framework experience
