MoneyMio

✳ From day zero

AI-powered personal finance: text an expense on WhatsApp and it's logged and categorized.

The project

Expense tracking usually dies in the first week, because opening an app and filling in a form is a chore. With MoneyMio, you just send a WhatsApp message: AI logs and categorizes the transaction on its own, no app needed. I founded MoneyMio and designed the company's entire technology, from backend to mobile, on a lean architecture that lets the business grow without the infrastructure bill growing with it.

Highlights

  1. The company's entire technical structure designed by me: backend, frontend, mobile and integrations.
  2. Low-cost architecture, built to scale without expensive infrastructure.
  3. The official WhatsApp API and LLMs categorizing every transaction automatically.
