How it works
Conversation
You tell me what you do and who you want to reach. I reply with a fixed-price quote, no fine print.
Page plan
I define the pages and the words your clients type into Google before writing a single line of code.
Development
You follow the website through a preview link and ask for changes along the way.
Live and on Google
I publish it on your domain, set up Google Search Console and hand everything over in your name.
04 Who builds it
You talk directly to the person who builds it
I'm Robinson Batista da Silva, a senior software developer with experience on projects for companies in Brazil and the United States. Authentic Development is my company: you deal directly with the person building your website, from the first message to launch.
05 FAQ
Frequently asked questions
How long does it take to build the website?
A landing page takes about a week; a business website with several pages takes two to four weeks, depending on when the copy and photos arrive.
Will my website show up on Google?
Every website ships with technical SEO in place: fast pages, titles and descriptions written for search, structured data, a sitemap and Google Search Console setup. Ranking also depends on content and competition, and no serious professional guarantees the top spot.
Do I have to pay a monthly fee?
No. You pay for the project, and the website and domain are registered in your name. Hosting is often free or costs a few dollars a month, paid directly to the provider.
Can I edit the website later?
Yes. We agree on it in the quote: you can get a blog you update yourself or ask for changes whenever you need them.
Do you work with clients anywhere?
Yes. Everything is done 100% remotely, over WhatsApp, email or video call, for clients anywhere in Brazil or abroad.
