Who you are hiring

Hiring someone you have never met to build a system for your clinic is a real risk. So this page puts everything you can check yourself in one place: the actual identity behind this, how the work runs, and things you can open and use in the next minute.

Identity you can verify

This is a registered sole trader, not a limited company, and I do not dress it up as a large team by writing we across the whole site. The contract is with me directly. The upside is that you are talking to the person doing the work from the first sentence, with no salesperson promising on a builder's behalf. The downside is that I can only take on a limited number of projects at once, which I say before taking yours.

How the work runs

Every clinic project follows the same four steps. Step two matters most, because you see the whole price before deciding, not partway through.

One call is enough to decide. Everything after it is in writing: the scope document, the contract and every decision, so both of us can always go back and check what was actually agreed.

01
A 15-30 minute call where I open the real thing

Book a time in the calendar at the bottom of the home page, then describe it the way you would to a friend. If something already exists, a spreadsheet you run on or a system still limping along, tell me how it is used.

02
Get the scope and the whole price, once

After the call I write up the scope, the price and any yearly running costs in a single document within 1 to 2 business days. Third-party costs like a domain or hosting are labelled separately so it is clear they are not my fee.

03
See the real thing before approving it

I send the data shape and the list of what the system will do before writing it, because changing a document takes ten minutes and changing half-written code takes three days. While it is being built, you can use the real system on my server.

04
You check it, then a handover someone else could pick up

You use the real system before the final payment, and anything that does not match what we agreed is fixed first. Then the source code, documentation, deployment instructions and the test suite where the project has one, all on accounts in your name.

03

Four things done differently here

Not written to sound good. Written so you can verify each one on this site yourself.

Prices are on the page

Every clinic package has a real number on the home page, and no form stands between you and seeing it. After the call, the whole price for your job comes in one document, and nothing is added to it later.

I open the real thing on the call

A clinic where patients book through LINE and a clinic that takes walk-ins at the counter need different systems from the very first screen. Any demo I could put online would always be one specific clinic's system, so I open the real system on the call instead. Not a screenshot and not a video.

You always get the source code

From the day of handover, and even if a project is cancelled halfway. You are never locked to me. The day you want a different developer, hand them the code and the documentation and they carry on.

Patient data security is not an add-on

I write my own security tooling and publish the code on GitHub. Systems I hand over have been looked at by someone who does breaking into things on purpose, not just made to work and left there.

04

Work you can open right now

The work page is not a gallery of pictures. The first few load the real applications into the page so you can use them, and the rest have their full source open.

05

What I stand behind

The short version here. The full terms are on the acceptance and refunds page, written to be read before you decide rather than buried in a contract.

Read the full acceptance and refund terms

  • You check the working system before the final payment, and anything that does not match the agreed scope is fixed free, however many times it takes
  • A reply within one business day, and delivery on the date written down before the work starts
  • Cancel before I start and the deposit comes back in full. Cancel after I start and the remaining stages are not invoiced, while you keep everything built so far with the source code. Once everything agreed is delivered and accepted, the final instalment is payment for work you already have
  • No promises about business results such as patient numbers or Google rankings, because nobody controls those
06

Contact me directly

Every channel reaches one person. Nobody in between and no automated replies.

A reply within 1 to 2 hours, and a written scope with the price within 1 to 2 business days. Those two are deliberately separate, because promising a price inside two hours only ends two ways: a rushed number that is wrong, or a broken promise.
