Custom PHP and MySQL application development in Mandurah

When an off-the-shelf plugin does not fit the business, I build the thing that does — booking systems, client portals, quote calculators, admin dashboards, and integrations with whatever API you already depend on. For Mandurah businesses, quoted in AUD from $200, typically live in 10 days.

Fixed scope, agreed in writing before development starts. From $200, typically live in 10 days.

The terms for a Australian client

Starting price From $200, quoted and invoiced in AUD
Typical timeline 10 days once content is supplied
Tax position GST at 10% on your sales; my invoices are GST-free imported services
Data protection the Privacy Act 1988 and the Australian Privacy Principles — resolved by APP 8 makes you accountable for an overseas recipient, so the DPA names Pakistan explicitly rather than burying it
Payment rails available Stripe, POLi and BPAY for deposits, and Afterpay where the basket supports it
My day in Mandurah time 15:00–00:00 — about 3 hours of overlap

Why this matters for Australia specifically

The timezone is the honest problem here and I will not talk around it: my working day lands in your afternoon and evening. Australian projects run on written asynchronous updates with one scheduled call a week, which works — but only because it is agreed up front.

The performance budget every Mandurah build is held to

Pages are built to a hard weight limit rather than optimised afterwards, because retrofitting speed onto a heavy site is several times the work of not making it heavy. In practice that means no framework runtime on a content page, fonts subset to the characters actually used, and images generated at the sizes actually displayed.

For Australia specifically this is a commercial number, not a vanity one. A visitor on mobile data who waits four seconds is frequently a visitor who is gone, and the analytics will record it as a bounce rather than as the lost sale it was. Core Web Vitals is simply the name Google gave to noticing this.

Manufacturing, wholesale and B2B in Mandurah

A B2B site in Mandurah serves two audiences with opposite needs. A buyer wants specifications, tolerances, lead times and a downloadable datasheet. A procurement officer wants your company registration, insurance, certifications and payment terms. Serving both from one undifferentiated "About" page serves neither of them.

The highest-value feature is almost always a searchable product or capability index carrying real part numbers, because that is what engineers search for. It is unglamorous, it is a database problem rather than a design problem, and it produces enquiries that arrive already qualified.

Images shipped at ten times the size they display

A hero photograph exported at 4000 pixels wide and displayed at 400 is the most common single cause of a slow page. The browser downloads all of it and then discards most of it. On a phone over mobile data that is several seconds spent waiting for pixels nobody will ever see.

The fix is generating each image at the sizes actually used, serving AVIF or WebP with a fallback, and setting explicit width and height so the layout does not jump while they load. It is mechanical work with a directly measurable result, which makes it the first thing worth doing on almost any Mandurah site.

What I am not claiming about Mandurah

Custom PHP and MySQL application development in Mandurah — common questions

Can you fix my existing site rather than rebuild it?
Often, yes, and it is usually the cheaper answer. Speed problems, a broken mobile layout, a form that silently fails or missing structured data are all fixable on the site you already have. I will tell you which of the two you need after looking, and a rebuild only gets recommended when the fix would cost more than starting again.
What hours will you be available to us in Mandurah?
My standard day lands at 15:00–00:00 your time — about 3 hours of genuine overlap with a normal Mandurah working day. That is enough for one reliable daily window rather than constant back-and-forth, so Mandurah projects run on written updates plus one scheduled call a week.
How long does a Mandurah project actually take?
Three days for a business site, seven for a store, ten for a custom application. That holds because the process is fixed rather than improvised and because your content exists on day one. What stretches a build is almost never the code — it is waiting for copy, logos and photographs, so those are requested before the clock starts.
What payment methods can my Mandurah checkout accept?
For Australia: Stripe, POLi and BPAY for deposits, and Afterpay where the basket supports it. The right combination depends on your average basket and your customers, and picking wrong is expensive — the payment method a buyer expects but cannot find is one of the most common reasons a checkout is abandoned at the final step.
Do you build on WordPress or something custom?
Whichever the project justifies. WordPress when you need to edit content constantly and want a familiar admin. A static build when speed and security matter more than a plugin ecosystem. Custom PHP and MySQL when the logic is genuinely yours. The choice is explained in the quote with its trade-offs, not presented as a foregone conclusion.
What happens if I am not happy with the result?
Work is delivered in milestones against a written scope, and you review each one on a staging URL before it is paid for. If the delivered milestone does not match the scope, it gets corrected before anything moves forward. That structure exists so disagreement is resolved at the stage it happens rather than at the end when it is expensive.
Will the site actually rank in Mandurah search results?
The build handles what is technically controllable: crawlable HTML, correct headings, structured data, fast pages, a clean sitemap and Search Console set up on day one. Ranking also depends on your competitors, your domain's age and the links pointing at you, which no developer controls. Anyone guaranteeing a position is guessing or lying.
