Want a tool like these built for you?

I built every tool on this site. I also take on small paid jobs: a calculator for your website, a simple site for your business, a bot, or a script that does a boring task for you.

You get a fixed price before I start, a working first version in a day or two, and plain answers the whole way.

What I build

• A calculator or tool for your website. A quote calculator, a savings estimator, a converter or a quiz. It runs in the visitor's browser, so there is no server to pay for. From A$90.
• A one page website. Fast, clear, right on phones, live on your own domain with nothing to maintain. From A$150.
• A Telegram bot. Takes bookings, answers questions, or turns a message into a document. From A$90.
• An automation or a data script. Clean up a spreadsheet, build a weekly report, or connect two apps so you stop copying and pasting. From A$80.

Work you can check

• Plenty of Tools: the 19 free tools on this site, from signing a PDF to recording your screen. Nothing you load is uploaded.
• Plain Invoice: invoicing for Australian sole traders, with accounts, card billing and a Telegram bot that turns a text message into a PDF invoice.
• Talkeven: a language exchange app I built and published on the Apple App Store.
• For clients: n8n automations, testing a finance tool built on n8n and Xero, and Shopify product templates.

How it works

1. Tell me what you need in a few lines. A rough idea is fine.
2. I reply with a fixed price, a date, and any questions.
3. You see a working first version early, then I finish it and hand it over with short instructions.
