# SaaS Platform & HTTP API Reverse Engineering
I’m looking for an experienced developer to build a **complete SaaS platform** inspired by an existing analytics/data service, including the backend, dashboard, shop, subscriptions, payments, user accounts, and API.
The data layer should reproduce the required functionality through **HTTP/HTTPS requests only** — no browser automation, Selenium, Playwright, or Puppeteer.
### Requirements
* SaaS development
* Dashboard & user accounts
* Subscription plans & billing
* Shop / product system
* Payment integration
* REST/API development
* HTTP API reverse engineering
* Python or Node.js/TypeScript
* Database & backend architecture
* Authentication & authorization
Experience building data/analytics SaaS platforms and working with undocumented HTTP APIs is a strong plus.
