PVSN.
Price Variation Software Network — a dynamic-pricing engine that moves prices up and down on 30+ live signals. The price moves; you don’t have to.
PVSN runs a store’s prices in real time on 30+ signals — time, weather, demand velocity, inventory, customer segment, competition. Prices move in both directions: up on peak demand and low stock, down to clear overstock and win back at-risk customers. Margin-protected, and every change logs its reasoning.
Under the hood: 190+ API endpoints on FastAPI and PostgreSQL, a React + TypeScript front end, and a Rust-accelerated pricing core — with 400+ backend and 280+ front-end tests behind it. It ships as a web app plus native apps for iOS (with an Apple Watch companion), Android, and desktop, with JavaScript and Python SDKs.
v3 is live at pvsnapp.com; public launch is July 25, 2026. Designed, built, and shipped solo — founder / CTO.
