About Me

A programmer born in the 80s with 18 years of code

👩‍💻

Started in 2008, witnessed the full evolution of the web — from table layouts to CSS Grid, jQuery to React, IE6 to Chrome.

Built enterprise Java systems, .NET desktop apps, Python data pipelines. Now focused on frontend engineering and browser extension development.

I believe good tools should be lightweight, privacy-friendly, and work out of the box. That's the design philosophy behind all my extensions.
