YC S11 · team ?
Jose is a strong backend engineer with 12 years of production systems experience and proven expertise in building scalable infrastructure, APIs, and multi-channel messaging systems. His work at Addie building real-time voice platforms with WebRTC, Twilio integration, and sub-200ms latency delivery across SMS, WhatsApp, and web directly mirrors OneSignal's omni-channel messaging needs. The main gap is that his recent focus has been more AI-first (LLMs, agents) rather than pure backend infrastructure, though his systems architecture and scaling experience remain highly relevant.
Hook: Your founding engineer at Addie built real-time voice and messaging delivery across 10+ countries at 99.9% reliability—exactly the omni-channel scale and reliability OneSignal needs.
Missing: Specific experience with push notification infrastructure, Background with large-scale message queue systems (Kafka, RabbitMQ), Mobile push notification protocols (APNs, FCM) deep expertise
