Chrome extension developer · Australian

The browser tool you wish existed, built for you.

I design, build and publish Chrome extensions: automation for repetitive web tasks, side-panel dashboards, page cleaners and blockers. Tell me what you want your browser to do and I'll make it happen, then get it onto the Chrome Web Store.

What I can build for you

If you do it in a browser more than twice a week, it can probably be automated or made easier. Here's the kind of work I take on.

Automate repetitive tasks

Clicking through the same forms, claiming daily rewards, bulk actions on a site. Record it once and let it run on a schedule.

Like: Task Recorder, X-celerate

Side-panel tools and dashboards

A panel that sits beside any tab with live data from an API, your to-dos or your team's numbers.

Like: Sports Sidekick, Pester Me

Clean up and block

Strip out feeds, ads, pop-ups or anything distracting from the sites you or your staff use every day.

Like: Reels and Ads Blocker, Forced Focus

Scan and flag pages

Read listings, highlight what matters and warn about what doesn't, on job boards, marketplaces or internal tools.

Like: GhostHunter

How it works

Send your brief

Use the form below or email me. Tell me what the extension should do and when you need it.

Get a fixed quote

I reply with what I'll build, a price and a delivery date. Nothing starts until you're happy with it.

Try test builds

You load early versions straight into Chrome and tell me what to change while I build.

Launch

You get the finished zip and source. If you want it public, I prepare the listing and submit it to the store.

How payment works

Simple and upfront, so we both know where we stand.

50% to start, 50% on delivery

A deposit secures your spot and work begins. The rest is due when the finished extension is ready.

Tune-ups: paid in full upfront

Pay by bank transfer

I invoice through Wise, so you pay a normal local transfer in USD, AUD, GBP or EUR. No card fees, no surprises.

Also accepted: PayPal (or Visa and Mastercard via PayPal invoice)

Three rounds of changes

Each job includes three rounds of revisions. Anything new beyond the agreed brief gets its own quote first.

14 days of bug fixes

If something in what I built breaks within 14 days of delivery, I fix it free. The full source code is yours once paid.

Tell me what you need and I'll email you back with a fixed price and a delivery date. No obligation.
