Jose has strong full-stack and backend engineering fundamentals with proven ability to ship production systems at scale, which aligns with OneSignal's infrastructure needs. However, his experience is heavily weighted toward AI/ML products, voice platforms, and real-time systems rather than email infrastructure and omni-channel messaging platforms. While he's built multi-channel delivery systems (web, SMS, voice, WhatsApp), there's no evidence of deep email deliverability expertise, SMTP protocol knowledge, or experience with email-specific challenges like bounce handling and compliance.
Hook: You've built real-time, multi-channel messaging systems at scale—your experience architecting delivery across SMS, voice, and WhatsApp to 10+ countries at 99.9% reliability translates directly to email infrastructure challenges.
Missing: Email deliverability and SMTP protocol expertise, Email provider integrations (SendGrid, AWS SES, etc.), Email compliance and legal requirements (CAN-SPAM, GDPR), Marketing automation or email platform experience, ISP relationships and sender reputation management
