Custom PHP and MySQL application development in Los Angeles

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 Los Angeles businesses, quoted in USD from $200, typically live in 10 days.

Why this matters for United States specifically

Most US small-business sites lose money at the same place: a contact form that asks for a phone number before it has earned one. American buyers self-serve further down the funnel than UK ones, so I push pricing and scope earlier on US builds.

Accessibility on a Los Angeles build, and why it is not optional

Keyboard navigation, real contrast ratios, form labels that are actually associated with their inputs, and alt text that describes rather than repeats. None of it is expensive when built in from the start and all of it is expensive to retrofit, which is the entire argument for doing it in the first pass.

The commercial case is simpler than the legal one: a site that a screen reader can navigate is a site that a search engine can parse, because both are reading the same semantic structure. Accessibility work and technical SEO overlap far more than either discipline usually admits, and in Los Angeles the same build serves both.

Retail and e-commerce in Los Angeles

A store is judged at the checkout, not the homepage. For United States that means the payment methods have to match what people actually use — Stripe, ACH via Plaid for larger invoices, and Shop Pay or Apple Pay at checkout — and the cart has to survive a slow connection and a page refresh. Most abandoned baskets are not indecision; they are a checkout that broke and gave no reason why.

The second issue is stock truth. A product page saying "in stock" when it is not costs you the sale and the customer, and the fix is unglamorous plumbing between wherever your stock actually lives and the storefront. That is worth a day of work far more than the product photography carousel is.

The contact form that silently fails

The most expensive bug on a small business website makes no noise at all. A form posts, shows a thank-you message, and the email never arrives — usually because the host's mail function is unauthenticated and the receiving server drops it without a bounce. The business concludes demand fell.

The fix is authenticated SMTP with SPF, DKIM and DMARC configured on the sending domain, plus a database write so a submission survives even when delivery fails. If you are unsure whether your Los Angeles site has this problem, submit your own form from a phone on mobile data and see what actually arrives.

What I am not claiming about Los Angeles

Custom PHP and MySQL application development in Los Angeles — common questions

Do you provide ongoing maintenance after launch?
Thirty days of snag fixes are included after launch at no extra cost — anything that does not work as specified gets fixed. Beyond that there are monthly plans for updates, backups, monitoring and small changes. They are optional and cancellable; a site handed over properly does not require a retainer to keep running.
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 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 Los Angeles 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.
What payment methods can my Los Angeles checkout accept?
For United States: Stripe, ACH via Plaid for larger invoices, and Shop Pay or Apple Pay at checkout. 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.
How do you handle our customers' data under state patchwork — CCPA/CPRA in California?
Your customer data is governed by a state patchwork — CCPA/CPRA in California, plus Virginia, Colorado, Connecticut and Texas equivalents, and sending it to a developer in Pakistan is a restricted transfer. That is resolved by a DPA with the sub-processor disclosure those state laws require you to publish, published on this site and pre-signed before you send an enquiry — not drafted after you ask about it.
What hours will you be available to us in Los Angeles?
Honestly: very little, by default. My standard day lands at 00:00–09:00 your time, which barely touches a Los Angeles working day. So United States projects run on a deliberately shifted schedule — I commit in writing to a fixed daily window that falls inside your morning, plus asynchronous written updates you can read before you start. If a supplier in your own timezone is what you need, that is a legitimate reason to hire locally.
