Workflow automation
Reduce repetitive browser actions with focused tools for research, operations, and daily tasks.
Browser tools, built around your workflow
Chrome Extension Development
Turn repetitive browser tasks into simple, reliable tools. We build custom Chrome extensions that add useful features to the websites and workflows your team already uses.

What we build
Useful extensions, not just toolbar buttons
From a focused personal tool to a multi-site workflow, each extension is designed around clear user controls and the browser permissions it actually needs.
Marketplace helpers
Add price calculations, listing context, and useful marketplace-specific controls where people shop.
Custom browser interfaces
Build clear popup settings, independent feature toggles, and controls that make complex tools easy to use.
Page integrations
Use content scripts to extend selected sites while keeping each integration scoped to its intended pages.
Manifest V3 architecture
Structure extension permissions, service workers, scripts, and browser storage for modern Chrome.
Maintenance and iteration
Improve an existing extension as target websites, user needs, and browser APIs evolve.
Featured project
Japan Shopping Assistant
A Chrome extension for international shoppers that shows estimated Japanese Yen prices for Mercari Japan listings and eBay search results, including estimated shipping on eBay. It can also apply eBay's “Located in Japan” filter, with each feature controlled independently from the popup.
