I’m building a multilingual, mobile-first website that brings ancient wisdom to the screen through modern, friction-free UX. The heart of the project is a real-time birth-chart generator: users enter birth data and instantly receive a full natal wheel, planetary positions, and concise interpretations. To keep calculations accurate and blazing fast, I expect an ephemeris-based engine (Swiss Ephemeris, NASA JPL, or a comparable library) wired into a React or Vue front end via a lightweight Node, Python, or Go API. Around that core feature I want a seamless flow into numerology insights, a crystal recommendation module, and guided manifestation rituals. Crystal suggestions must explicitly cover: • Healing properties • Personalized based on user input • For specific rituals or purposes The manifestation section will house step-by-step audio, video, and text rituals that users can save to their profile. Clean navigation, account security (OAuth or JWT), and a CMS so I can update content without touching code are essential. If you can structure the site so future languages plug in easily—ideally via i18n files or a headless CMS—bonus points. Please propose: 1. The stack you’d use, mentioning any astrology, numerology, or charting libraries. 2. A brief roadmap from MVP to full launch, including time for testing accuracy of chart data. 3. Any past work that shows you’ve handled complex real-time calculations or spiritual content. I’ll provide all copy, artwork, and ritual scripts; you handle architecture, coding, and deployment to a cloud host (Vercel, Netlify, or AWS are all fine). Deliverables are the full source in Git, a live staging URL, and clear setup docs. Once live, users should feel they’ve stepped into a digital sanctuary that guides them from first click to transformative insight.
