• Engineer real-time booking systems with web sockets handling guest communications, pricing updates, and multi-platform synchronization
• Deploy features at breakneck speed using AI-powered development to maintain competitive advantage
• Scale high-performance applications managing millions of bookings and guest interactions
• Maintain enterprise-grade code quality while maximizing AI-assisted development velocity

• Claude Code integrated for all coding tasks
• Production experience with Figma MCP workflows
• Concrete examples of 5-10x development speed improvements through AI

This role isn't for you if:
