About this gig

Need a custom tool inside Google Sheets, Docs, or Gmail that goes beyond a simple script? I build Google Workspace add-ons: proper, packaged extensions with their own menu, sidebar, or dialog UI, not just a macro buried in Tools > Script editor.


I have published my own Google Workspace Marketplace add-ons, so I understand the platform inside and out: manifest files, OAuth scopes, add-on triggers, and Google's review process.


Here is what I can build for you: container-bound add-ons with a custom menu, sidebar, or card UI; editor add-ons for Sheets, Docs, or Slides; Gmail add-ons that pull in data or automate replies; standalone add-ons with external API/OAuth integration, ready for Marketplace submission; and clean, documented Apps Script code you can maintain yourself.


Why work with me: I write clear, well-structured Apps Script, not spaghetti code. I test everything thoroughly before handing it over. And I explain how it all works, so you are never stuck.


Send me a message with what you need your add-on to do, and I will tell you the best plan for it before you order.
