FOUNDER & AI ENGINEER

Federico Madoery

I co-founded two Web3 startups. I also build AI tools and integrations that power other companies' platforms, from healthcare messaging to agent infrastructure. Ten years getting things into production.

02 / About

From Gálvez to two Web3 ventures

I grew up in Gálvez, a small town in Santa Fe, and I've spent close to ten years building software. These days I split my time between Santa Fe and Miami.

In 2022 I co-founded TheBadge, a way to verify credentials on Ethereum. The same team then built OpenGrano, which gets small Argentine farmers the financing that banks turn down — funded instead by crypto investors anywhere in the world.

At FolderIT I lead engineering for client companies, embedding with their teams to build their products and grow our AI practice — these days that means building harnesses and tooling for AI agents. One of those clients was OhMD, where I spent four years on a HIPAA-compliant healthcare platform. I also teach at UTN FRSF, where over the years I've covered Data Structures, Mobile Development and Cloud Development — and standing in front of a class is what sharpened how I explain ideas, break down problems, and lead a team.

03 / Experience

Where I've worked

  1. AI Engineer / Tech Lead

    2017 — Present

    FolderITCurrent

    I lead engineering embedded inside client companies, building their products alongside their teams. Lately I run FolderIT's AI practice, building the harnesses and tooling that AI agents run on.

  2. Co-founder · CPO

    2024 — 2025

    OpenGrano

    Working capital for Argentine farmers the banks turn away, raised from crypto investors worldwide and backed by the crop itself. Built on Avalanche.

  3. Co-founder · CPO

    2022 — 2025

    TheBadge

    Real-world credentials you can verify on Ethereum, with disputes settled through Kleros. I designed and wrote the verification systems behind it.

  4. Senior Software Engineer

    2022 — 2026

    OhMD

    Four years on a HIPAA-compliant platform that lets clinics reach patients over SMS, voice, video and email. On Elixir and Phoenix, I helped build the secure messaging and the AI engine that classifies incoming patient messages, alongside the frontend platform. Client work via FolderIT.

  5. Tech Lead

    Earlier role

    Escalante Cloud

    Real-estate lead routing on an event-driven AWS stack, deciding which agent takes a new lead in under a minute. I also built the generator behind a million-page SEO site. Client work via FolderIT.

  6. LST Developer

    Earlier role

    Macmillan Learning

    Study apps on Macmillan's e-learning platform, one of them serving around a million requests a day, with interfaces built to pass real screen readers. Client work via FolderIT.

  7. Software Developer

    2015 — 2017

    Freelance

    Where it started, before FolderIT: React Native banking apps — virtual wallets, remote loans — plus web work in React and Node.js.

04 / Startups & Ventures

Two companies, one crew

Two companies, one co-founder beside me the whole way: Agustín Pane. Both chase the same conviction — that the things people trust most, credentials and capital, work better on open rails than behind a gatekeeper.

TheBadge

Role

Co-founder · CPO

Diplomas, licenses, certifications — the proof of who you are and what you can do — sit locked in PDFs and private databases, easy to fake and impossible to carry. TheBadge makes them yours: portable, tamper-proof, and provable to anyone, with no single authority deciding what counts.

The bet

We built it as open infrastructure, not a walled-garden app — standards any institution can issue on. I co-founded it with Agustín Pane and led the product.

OpenGrano

Role

Co-founder · CPO

A grain producer's biggest asset is a harvest that doesn't exist yet. OpenGrano turns that future yield into an on-chain asset global crypto capital can fund directly: the farmer gets liquidity, the investor gets real-world returns, and the bank sits out.

The bet

Avalanche picked us for its Codebase incubator, about 15 projects out of ~500, and its Buenos Aires Innovation House, alongside partners like INTA and agri-tech companies. Same co-founder as TheBadge: Agustín Pane.

Open Source

Open-source work

A few things I've put out in the open.

AI memory · MCP

coderecall

A local-first MCP server that gives a coding agent a memory of your repo: hybrid code search plus a knowledge store, in one SQLite file, no API keys.

GitHub

React hook · npm

caret-coordinates-hook

A tiny React hook that returns the pixel position of the text caret. Handy for floating menus, mention pickers, and inline tooling.

npmGitHub

Libraries · contributions

Web3 open source

Smart contracts, SDKs, and subgraphs from TheBadge and OpenGrano, plus fixes pushed upstream to the libraries they depend on.

GitHub

Agent & MCP experiments

Private AI tooling

Agent and MCP experiments I keep private for now. They're where the open tools above usually start.
