I am a solo software engineer and I spent the last few months working on a major technical challenge: building a fully operational AI Astrology and Tarot SaaS (sidusastro.com) where all astronomical math runs 100% client-side.
To avoid expensive third-party data APIs, I compiled the official C-based Swiss Ephemeris library into WebAssembly (WASM) to run directly in the browser. The platform has over 16k lines of clean React 19 and TypeScript code, wired with 9 Netlify Serverless Functions, Firebase Auth, and full Stripe Checkout subscription hooks.
It features:
High-precision natal charts and planetary transits via WASM
A guardrailed OpenAI Oracle chat (system-prompted to only answer esoteric queries).
An AI psychological dream interpreter.
Interactive Tarot (6 complex spreads), numerology, and synastry radar.
Native bilingual routing infrastructure (PT/EN) and responsive UI.
Why am I here? I have absolutely zero marketing skills, and the project is sitting at pre-revenue with zero traffic. I am moving on to data infrastructure work and I want to release this turnkey codebase to a growth marketer or agency who can run with it.
I am selling the complete GitHub repository ownership, setup runbooks, and the premium domain name (sidusastro.com/en) for a flat
$500 USD via Escrow.com.
If you want read-only access to inspect the repository or want to talk about the asset handover, drop a comment below or send me a DM with your GitHub username. Let's make a deal this week.
