About this gig

Do you have an idea for a browser extension but don't know how to build it? I'll turn your idea into a fully working, installable extension for Chrome and Firefox.


I specialize in productivity-focused extensions. Lightweight tools that help you work faster, stay organized, and cut out repetitive tasks right from your browser. No complicated software, no subscriptions, just a clean extension that does exactly what you need.


What I can build:

  • Tab managers and organizers
  • Focus timers and Pomodoro tools
  • Note-taking and quick-save tools
  • Custom new tab pages and dashboards
  • Reminder and notification tools
  • Page modifiers and custom shortcuts
  • Any other productivity utility you have in mind


What you'll receive:

  • Fully working extension compatible with Chrome and/or Firefox
  • Clean, well-structured source code
  • Simple installation instructions
  • Revisions included (see packages)


Why work with me? I've shipped real products like SendIt (trysendit.app), a live cross-device file transfer web app I built and maintain. You're hiring someone who builds things that actually work.


Send me a message and I'll build the tool for you!

Hey! I'm Silford, a developer who loves building focused, practical tools that actually solve problems. I specialize in browser extensions and web utilities. I've shipped real products, including SendIt (trysendit.app), a cross-device file transfer tool I built and maintain as a live web app. I ask the right questions upfront, keep you in the loop, and don't disappear on you mid-project. Whether you need something simple built quickly or a more complex tool that needs some thinking through, I've got you. If you have an idea for a browser extension or web tool, let's build it.
