From code to digital presence

A one-person agency based in Taubaté, Vale do Paraíba, Brazil. I deliver what usually takes a team — system, website, app and the marketing layer — choosing the right technology for each client, not the one I already use.

How it works

Our process

  1. 01. Conversation and diagnosis

    I get to know the business, who the customer is and what's holding things back today. No generic form: it's a conversation, in person or on a call.

  2. 02. Proposal and technology choice

    Fixed scope, deadline and price in writing — and a stack chosen for the problem, not for the hype. You know what you'll get before we start.

  3. 03. Structure and design

    Screens and flows designed around what the team already does. You see and approve before anything becomes code.

  4. 04. Build

    Development with partial deliveries so you can follow, test and adjust along the way — no disappearing for a month.

  5. 05. Launch and follow-up

    Live with domain, hosting and analytics configured. After delivery, I stay close for adjustments and evolution.

Shall we make your idea real?

No generic solution: a conversation to understand the scenario and a path designed for your business.
