Where most teams get stuck

Off-the-shelf tools
don't fit how you work.

Hours slipping away

People copying data and answering the same question all day.

Nothing talks

CRM, calendar, ERP and chat, each on its own island. Everything typed twice.

A project that never ships

You have the idea. The freelancer vanishes, the agency costs a fortune.

The turn

Everything you use,
in one operation.

Built to fit your process and your data. App, system, automation and AI working from one source, with nothing typed twice.

Why Dcoder

A real company

Registered company, written contract and invoice. You hire with a paper trail.

The asset is yours

Code in your repository, no third-party subscription holding you hostage.

Pricing

Priced in US dollars.
No fine print.

Monthly partnership
From US$ 1,100/month

Up to 20 hours a month of an engineer looking after your software: new features, fixes, technical decisions. Priorities reviewed every month, no frozen scope.

Fixed-scope project
From US$ 1,100

Priced by what it delivers and by the deadline, never by the clock. Scope and price in writing before any code.

Extra hours
US$ 55/hour

For work beyond the monthly hours or outside the agreed scope. Agreed with you before it happens.

The usual path is to start small. One entry project, delivered and paid. If it works out, it becomes a monthly partnership. That is how almost every client working with me today started.

Written contract and invoice included. Work starts after the deposit.

FAQ

What everyone asks.

The monthly partnership starts at US$ 1,100 per month for up to 20 hours of engineering. Fixed-scope projects are priced by what they deliver and by the deadline, with a minimum of US$ 1,100. Extra hours and out-of-scope requests are US$ 55 per hour. After a 20-minute call you get the scope and the price in writing.

The studio is in Belém, Brazil, on UTC−3 all year round. That is one or two hours ahead of New York and three or four hours behind London, so calls fit a normal working day in the Americas and the afternoon in Europe. Most work runs asynchronously in writing, with calls when a decision needs one.

Prices are in US dollars. Every engagement has a written contract and an invoice from a registered Brazilian company. Payment terms are set in the proposal, and work starts after the deposit.

No. The studio builds any custom software: web apps, SaaS, e-commerce, integrations and automation. AI is used when it helps your case, not as decoration.

Yes. The existing code can be extended, fixed or integrated, as long as there is access to it. The current state is reviewed before any proposal.

You do. The code lives in your repository and the software is your asset, with no third-party tool locking you into a mandatory subscription.
