What I do

Tell me where it hurts. I'll propose the simplest fix.

  • Your team copies data from one system to anotherA process automation does it on its own, on schedule, and lets you know when something looks off.
  • The spreadsheet can't keep up anymoreA web system with login, history and reports, built around the way your team works.
  • Your customers need an appAn app for your business, on Android and iPhone, connected to the same system your team uses.
  • Your numbers are scatteredA data dashboard that brings everything together and shows what matters.
  • You don't show up well online yetA fast website that explains what you do and brings in quote requests.
  • Your team types in data from PDFs and invoicesAn AI that reads documents fills in the system and flags what needs a review.
How I work

You know the price before we start

  1. Free assessmentA 30-minute video call to understand how things are done today and tell you whether it calls for a system, an automation, or nothing at all.
  2. Written scope and priceBefore any work starts, you get the scope, the timeline and a fixed price.
  3. Delivered in stagesYou see each stage working and test it before the next one begins.
  4. Support afterwardsThe code and the data are yours. Adjustments and hosting are available as an optional monthly plan.
  • 30 days of free adjustments after delivery.
  • You only pay for the next stage after approving the previous one.

Every project comes with a written contract and an official invoice from my registered Brazilian company (CNPJ).
