Full-Stack Developer for a Mobile-First AI Reflection Web Prototype

I need an AI-first full-stack developer to build a mobile-first web prototype for Mirror, an AI self-reflection product that gradually builds a structured personal model from user input. The product logic and acceptance criteria are already defined, so I’m looking for someone who can implement the prototype efficiently using modern AI coding tools. This is a fixed-budget project. The fixed-price budget is USD 1,500 for the complete pilot. Please specify what you can deliver within this amount and list any hosting or AI usage costs separately.
