  3. Building

    Private repository

    Overview

    A web app that takes Brazilian micro-entrepreneurs from informal work to a registered MEI, then keeps the business organized, in plain language instead of accountant jargon. It is one of the two products I'm building at Hyphen, the startup I founded.

    What it does

    • Guides for opening a MEI, paying the monthly DAS and filing the annual declaration
    • Monthly and yearly obligations, with reminders
    • Business money kept apart from personal money: income, expenses and a monthly overview chart
    • Designed phone first, for one-handed use

  4. Building

    Private repository

    Pharmaceutical management system for monitoring and controlling sales and medication inventory across all basic health units in the municipality of Igarassu.

    • NextJS
    • Typescript
    • TailwindCSS
    • shadcn/ui
    • Supabase
    • Zod
    • React Query
    • MVVM Architecture

    Overview

    It starts as a pilot in the pharmacy of a single Basic Health Unit (UBS) and is designed to grow to every unit in the municipality without rework. It is the second product I'm building at Hyphen, alongside ZeroAoMEI.

    What it does

    • Entries and exits recorded at the pharmacy counter, so the balance on screen can be trusted
    • Each unit keeps its own categories and medicines, isolated by row-level security
    • A network admin panel that reads every unit
    • A Next.js front end that talks to a FastAPI back end, which queries Supabase with the user's own token

Shall we build something together?
