Datachain Rio

Custom development · Rio de Janeiro and the metropolitan area

Does not fit a template? Then I build it custom.

A client portal, an integration with your calendar or your management system, a website with dozens of pages or a design that is entirely your own. You always receive a fixed price, never an open-ended bill.

What I build custom

Your own design

An existing visual identity, or a website with more than 6 pages and a structure that is yours alone.

Integrations

Appointments, reservations, a product catalog fed from your inventory system or a link to your management system.

Protected environments

A client portal or an intranet with login, properly isolated and audited. This is where my security work counts the most.

How you get to a fixed price

  1. 1First call of 30 minutes. What does it need to do, for whom, and how does it work today?
  2. 2Short description. I describe the pages, features and integrations, and what you supply. For a large project this is a paid preliminary study, at R$ 290 per hour.
  3. 3A quote with a single price and a schedule. I only start after your go-ahead.
  4. 4Built in stages. You see intermediate results and can adjust course. Changes outside the quote I estimate first.

What you can count on

  • The same technical foundation as my templates: fast, accessible, hardened security
  • No unnecessary systems: whatever can be static stays static
  • The code and files are yours
  • Maintenance from R$ 249 per month, with the same clear agreements

Questions about custom projects

Why is there no price on this page?

Because every custom project is different. An extra page with its own structure is one thing; a portal with login is another. After the first call you always receive a single fixed price.

What if the project grows during the build?

Then I estimate the extra requests first. You decide whether to include them. Nothing is built without your go-ahead.

Do you work with a designer or copywriter?

Yes. If you already have a designer, I work with their design. If not, you can hire someone in Rio and I fit into the process; third-party work is outside my quote.

Ready for a website that works and is secure?

Tell me what you want to achieve. You get a reply within 1 business day and, within 2 business days after our call, a quote with a fixed price.
