Web developer in Campinas

Websites, online stores and technical SEO for Campinas businesses — built remotely from Islamabad, quoted in BRL, scoped in writing before anything starts.

If your Campinas business gets most of its work through word of mouth, your website has a narrower job than you have probably been told. It is not there to find strangers. It is there to reassure someone who already has your name and is checking whether you look real. That is a much easier site to build, and much cheaper.

What working with a Brazilian client actually changes

These are the terms that differ by country rather than by town. They apply to every business in Brazil, Campinas included, and they are the substance of what this page is claiming.

Quoted and invoiced in BRL — never a converted figure presented at the end
Tax position a layered ICMS and ISS regime that varies by state
Your customers' data sits under LGPD, the Lei Geral de Proteção de Dados
Lawful transfer mechanism a DPA meeting ANPD requirements for international transfer
Checkout can realistically use Pix, Mercado Pago, PagSeguro, and boleto bancário

One thing worth knowing about building for Brazil

Pix settles instantly and free, and it took over Brazilian payments faster than almost any rail anywhere. Any Brazilian store without Pix is charging itself card fees for no reason and losing buyers who expect it.

How a Campinas project is paid for, and why it is staged

Payment is split across milestones tied to things you can actually look at — a staging URL, a working checkout, a completed migration — rather than to dates on a calendar. You pay for a milestone after reviewing it, in BRL, which means at no point are you more than one stage out of pocket on work you have not seen.

This exists because the alternative puts all the risk on whichever side pays first, and across a border that asymmetry is the thing that makes people nervous. Staging it does not eliminate the risk; it caps it at one milestone, which is small enough to walk away from. That is a more honest offer than a guarantee I could not enforce from here anyway.

Property, lettings and estate agencies in Campinas

Property sites live or die on search and filtering. A listing grid that cannot be filtered by the three things buyers actually care about — price, bedrooms, area — sends people to the portals, and once they are on a portal you are competing on fee with every other agency in Campinas.

The technical half is feed handling: listings usually arrive from a CRM in a format designed two decades ago, and keeping the site, the portals and the window cards in agreement is where the real work sits. It is worth doing properly, because a property still showing as available after it is let generates the angriest phone calls in the business.

Analytics that has never once been looked at

Most sites carry a tracking tag and no measurement. Nobody defined what counts as a conversion, so the dashboard reports sessions and bounce rate — numbers that move up and down and change no decision anybody makes.

Useful measurement is narrow: form submissions, phone taps, WhatsApp clicks, and which pages preceded them. Four numbers checked monthly beat forty never opened, and knowing which Campinas search terms actually produce enquiries is what turns the site from a cost into something you can steer.

Hiring a developer who is not in Campinas

Working across a border adds one genuine obligation most suppliers skip: your customers' personal data ends up being processed in a country their privacy notice probably does not mention. Under LGPD that is your liability, not mine. It is handled here before you ask — the mechanism is published, pre-signed and linked from every page on this site.

What I build for Campinas businesses

Fixed-scope, fixed-price, quoted in BRL. The full list is on the services page.

E-commerce website development I build online stores end to end — catalogue, cart, Stripe checkout, order emails and the technical SEO that gets them found. Six of the fifteen sites I have shipped are e-commerce builds, and every one of them takes real payments. From $150 · 7 days Technical SEO audits and implementation Most SEO audits hand you a 60-page document and an invoice. I am a developer first, so I find the problems and then fix them in the codebase — crawlability, indexation, schema, Core Web Vitals, and whether AI answer engines can read your site at all. From $80 · 3 days Business website development Most small business websites fail at one job: turning a stranger who searched for your service into a phone call. I build the version that does — three days, mobile-first, live on your own hosting, with the enquiry form tested before anybody sees it. From $80 · 3 days Custom website development A template is the right answer more often than developers like to admit. This page is about the times it is not — when the thing your business does has a shape no theme author anticipated, and forcing it into one costs more in permanent workarounds than building it properly would have cost once. From $200 · 10 days Web application development A website presents information. An application does work — it holds state, enforces rules, and produces something at the end. Most businesses that need the second one are running it on a spreadsheet nobody is allowed to sort, and paying for that in errors rather than in software. From $200 · 10 days

What I am not claiming about Campinas

A location page is the easiest place on a website to imply something untrue, so here is the other side of it plainly:

Campinas web development — common questions

Do you actually work with businesses in Campinas?
Yes, remotely. I work with Brazilian clients from Islamabad, quoting in BRL and invoicing in BRL. I have no office, address or phone number in Campinas and will not pretend otherwise. If your project needs someone physically present, hire locally — I will say so in the first reply rather than after a deposit.
How much does a website cost in Campinas?
A business website starts from R$440 and goes live in about three days. An e-commerce build starts from R$830 in around seven days, and a custom application from R$1,100 in ten. Those are starting figures — the exact number is fixed in writing once scope is agreed, and it does not move after that.
What currency will I be invoiced in?
BRL. Quotes, milestones and the final invoice are all written in BRL so you are never comparing a converted figure against a local supplier's. Regarding tax: a layered ICMS and ISS regime that varies by state.
Who owns the website when it is finished?
You do, completely. The domain is registered in your name, hosting sits in your account, the code lives in a repository you control, and any payment provider account is opened in your business name. Credentials are handed to you as they are created rather than at the end, so you are never locked out of your own site.
How do you handle our customers' data under LGPD?
Your customer data is governed by LGPD, the Lei Geral de Proteção de Dados, and sending it to a developer in Pakistan is a restricted transfer. That is resolved by a DPA meeting ANPD requirements for international transfer, published on this site and pre-signed before you send an enquiry — not drafted after you ask about it.
What payment methods can my Campinas checkout accept?
For Brazil: Pix, Mercado Pago, PagSeguro, and boleto bancário. 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 Campinas 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.

Where this page sits

This page covers Campinas. Every other town in Brazil is listed on the Brazil coverage page, and the full worldwide list is at all locations.

Before you enquire: pricing is published rather than quoted on request, how I work covers the process end to end, the work page lists live client sites you can open, and vendor information answers the procurement questions.
