Seller Price Operations | Playwright, Electron & APIs
Andrey Mikhaylov
An Ozon seller needed to work with the dynamic green price visible to shoppers. The Seller API used in this project did not return that figure.
I built an Electron/Node.js application that combines catalogue data with an actual Playwright browser visit. It records the displayed price, calculates the new seller price, sends the update through Seller API and revisits the product page to check the outcome.
Batch controls and SQLite history keep observations and updates traceable. Role: workflow design, interface, browser automation, API integration and local storage. This is an independent seller tool, not a commission from Ozon; price figures shown are examples.
Selected screens
Price update — review the observed storefront price and calculate the seller-price adjustment.
Verification — compare the update with the next storefront observation.

A seller tool that reads the storefront price, calculates a new seller price, updates it through the API and checks the result.
