I'm a Learner and Technology Services Specialist at Harvard Business Publishing, where I run the EU Datacenter. Before that I helped merchants succeed on Shopify and BigCommerce and built training for hundreds of people — a bridge between technical depth and human connection, in eCommerce, SaaS support, and high-stakes L&D environments.

Portfolio

Selected Work

Things I build on my own time, usually to scratch a very specific itch.

Featured · Chrome extension + native host

AHK Hotstring Clipper

Select text on any web page, press Alt+Shift+H, type a trigger, and it's written as an AutoHotkey v2 hotstring into your own .ahk file and live within a second. Under five seconds start to finish, without reaching for the mouse.

  • Two-part architecture. A Manifest V3 extension in TypeScript talks over Chrome native messaging to a small Go host that does every disk and AutoHotkey operation.
  • Local only, and verifiably so. No accounts, no cloud; a release-time check fails the build if the extension or the Go host could reach the network.
  • Built for daily use. Live preview of the exact line written, duplicate detection across a whole folder, 10-second undo, and a manager view with search, edit, move, delete and CSV import/export.
  • Tested end to end. TypeScript and Go unit tests share one set of fixtures, plus browser e2e tests and a PowerShell installer that needs no admin rights.
