Custom PHP and MySQL application development in Grenoble

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 Grenoble businesses, quoted in EUR from $200, typically live in 10 days.

Why this matters for France specifically

The CNIL enforces cookie rules more aggressively than most EU regulators, and "refuse all" must be as easy as "accept all". A French site running a standard one-button banner is carrying a known, fineable defect.

Accessibility on a Grenoble 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 Grenoble the same build serves both.

Retail and e-commerce in Grenoble

A store is judged at the checkout, not the homepage. For France that means the payment methods have to match what people actually use — Cartes Bancaires, Stripe, Lydia, and PayPal — 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.

A redesign that quietly deleted the rankings

The classic disaster: a new site launches, looks far better, and organic enquiries fall off a cliff within a fortnight. The cause is almost always identical — the URLs changed and nothing was redirected, so every page that had accumulated years of authority now returns a 404.

Preventing it is a redirect map built before launch: every old URL to its closest new equivalent with a 301, and anything without an equivalent pointed at the nearest relevant page rather than the homepage. If your Grenoble site is being redesigned by anyone, ask to see that map. If it does not exist, that is the entire risk in one document.

What I am not claiming about Grenoble

Custom PHP and MySQL application development in Grenoble — 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.
Will the site actually rank in Grenoble 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 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.
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 payment methods can my Grenoble checkout accept?
For France: Cartes Bancaires, Stripe, Lydia, and PayPal. 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 long does a Grenoble 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 hours will you be available to us in Grenoble?
My working day lands at 06:00–15:00 in your time, which is roughly 6 hours inside a normal Grenoble working day. In practice you can raise something in the morning and have it answered the same morning, and a scheduled call is easy to place at a civilised hour for both of us.
