Tech stack: Next.js, MongoDB, Chrome Extension

Links: View Project, View My Depop

Bumpy.Pro combines a Chrome extension with a Next.js web application backed by MongoDB. The extension automates likes, follows, unfollows, and refresh patterns intended to resemble human pacing; the web app reports usage and configuration.

The product allowed substantially higher daily follow volume than some competing tools (the author cites up to 7,500 follows per hour with a follow-back rate of roughly 5% in testing). Personal testing on a linked Depop account informed tuning.

The extension progressed toward Chrome Web Store review; the stack includes authentication, synchronisation between extension and server, throttling, logging, and error handling. Automation against third-party sites carries policy and account-risk considerations that users must judge for themselves.
