AI Full-Stack Developer – Build AI Birth Chart & Karmic Donation Alignment MVP

Project Overview I'm building an AI-powered web application that combines astrology with personalized philanthropy. The MVP will generate a user's birth chart using an astrology API and use GPT/Claude to create a personalized report recommending charitable cause categories ("karmic donation alignment") based on the birth chart. This is NOT an astrology app. It is the first version of an AI-powered purpose and giving platform. Project Scope Phase 1 MVP 1. Landing Website Modern responsive UI Product overview Pricing page Contact page 2. User Intake Collect: Name Email Date of birth Exact birth time Birth location 3. Astrology Integration Integrate an astrology engine (preferred: Swiss Ephemeris or a reliable astrology API) to calculate: Sun sign Moon sign Ascendant Planet positions Houses Major aspects 4. AI Report Generation Integrate OpenAI GPT-4o or Claude API. Generate a personalized report including: Personality overview Strengths Challenges Life purpose themes Karmic donation alignment Recommended charitable cause categories Note: At this stage, AI recommends cause categories only (e.g., education, healthcare, animal welfare). It does not select or rank individual charities. 5. PDF Report (Optional) Generate a professional PDF report that users can: View online Download Receive via email 6.
