I build AI that real operations run on. A hospital network, WhatsApp storefronts, and the agents that read your documents.

Chapter I

The Manifesto

What I believe about life and about building. Each belief is paired with the work that shows I live by it.

We get one life. I refuse to spend it as a spectator. The future is not something that happens to us. It is something we build, with our own hands, one version at a time. I want to own my days, chase the dreams that scare me, and leave a dent in the universe that outlasts me. From Bogotá, with AI as my team, I am building it now.

BrayanBogotá · September 2026

  1. Build what should exist.

    Not what is easy. Not what is trending. The things the world is quietly waiting for.ETHER runs every day inside a public hospital network.

  2. Ship it. Then make it insanely great.

    The first version is a promise. Every version after is how you keep it.ETHER Mark I used keyword matching, and said so. Mark VII runs four AI agents.

  3. Great technology disappears.

    The best software never asks people to change. It meets them exactly where they already are.Technicians close tickets and buyers place orders, all from WhatsApp.

  4. Speed is a form of respect.

    Every day a problem stays unsolved, someone pays for it. Moving fast is how I honor their time.879 commits in 2026. Seven versions of ETHER in seven months.

  5. Truth over applause.

    Measure against the old way. Publish what stalled. Hype expires. Credibility compounds.16.3% vs 11.6% on the same conversations, published with the limits of the sample. The ledger lists every project, including the paused ones.

  6. Trust is the product.

    People hand us their health, their money, their names. Guard it as if it were your family's.Nightly tests that sign in as every role. Tools that never upload a file.

  7. Focus is saying no.

    Every yes costs a thousand others. Knowing what to stop is part of building what matters.LimpioGO became MANO. MANO is paused. Both are on the record.

  8. One mind. An army of agents.

    AI is the most powerful bicycle for the mind ever built. I set the vision, agents multiply the hands, and I own every result.Specs, reviews and tests in every repository.

  9. Where you start is your advantage.

    Building from Latin America means seeing up close the problems others only read about, then solving them for the world.Customers in Colombia and Argentina. Packages on npm, PyPI and the MCP Registry.

  10. Sign your work.

    Care about the parts no one will ever see. Craft is how you tell the universe you were here.You are reading one.

Selected Works

Shipped, in use, measured, and the ones that taught me the most. Open any case for the problem, what I built and the result.

01 · Built soloIn production

ETHER

The AI maintenance platform a multi-site public university hospital network runs on every day.

  • 145commits, April to September 2026
  • 4AI agents: dispatcher, deadline watcher, closure auditor, weekly report
  • 7major versions in seven months
Open the case

Problem

Hospital engineering teams handle maintenance requests across several sites, each with a deadline, a technician and a sign-off. Phone calls and chat do not scale.

What I built

Deadlines in business days, no-login reporting by QR code or voice, WhatsApp operations for technicians, tool lending, a contractor portal, and an assistant that acts on tickets through tool calls. Four departments on one platform.

Why me

I work in the hospital's engineering department. I build next to the people who use it.

ZAVORA

AI agents that take, price, charge and record orders over WhatsApp, from text, photos or voice notes.

  • 16.3%of conversations closed as sales, vs 11.6% for the rules bot (Aug 2026)
  • 1 of 20Innovalab batch 3 winner, Bogotá Chamber of Commerce
  • 183of my commits in September: public API, SDK, MCP server, payments
Open the case

Problem

At GoFest 2026, the businesses that stopped at our stand kept describing the same scene: a WhatsApp inbox overflowing with orders.

My part

Co-founded with Camilo Abella, who leads product and the conversational agent. I lead integrations and the platform: Shopify two-way inventory, Mercado Pago, Wompi, Alegra e-invoicing, Kommo CRM, a public API with idempotency, rate limits and webhooks, a Python SDK, an MCP server, and OIDC deploys with rollback.

Sırdaş

Privacy-first PDF tools for AI agents. Markdown, anonymization and datasets, without uploading a single file.

  • 6ways to use it: web, CLI, library, MCP server, n8n node, Python
  • 223npm downloads in the first eight days
  • Oct 20public launch, 2026
Open the case

Problem

Teams want to give contracts, medical records and invoices to AI, but those files carry personal data that cannot go to someone else's server.

What I built

One engine that runs entirely on the user's machine, with OCR in WebAssembly. Four npm packages and a PyPI package published Sep 17, 2026, plus an MCP Registry entry.

MANO

A two-sided mobile marketplace that connects companies with vetted cleaning, maintenance and logistics crews.

  • 79commits in eight weeks, May to July 2026
  • ~20serverless functions: live map, QR and GPS check-in, escrow payments, an AI assistant
  • 5 daysto build LimpioGO, its B2C predecessor, before pivoting to B2B
Open the case

Problem

Companies need reliable crews on short notice, and independent workers need steady jobs and to get paid on time.

What I built

An Expo app with a live map, QR and GPS check-in to prove the work happened, escrow payments through Mercado Pago, training mini-courses, and "Maia", an AI assistant. It started as LimpioGO, a home-cleaning app with photo-to-quote pricing via Claude vision, and pivoted to serve companies.

LOK

Credit offers built from consented Open Finance data, so people get a fair answer before they even ask.

  • 4agents: reader, scorer, originator and guardian
  • MFArequired for financial data, with AES-256 column encryption and an append-only audit log
  • 1self-correction that mattered: dropped email and calendar signals for policy reasons and moved to Open Finance
Open the case

Problem

Many people in Latin America are invisible to traditional credit scoring, even when their finances are healthy.

What I built

A consent contract, bank connection through an Open Finance provider, a digital-footprint check, a rules classifier with a machine-learning fallback, a personalized offer engine, and a Habeas Data erasure routine. Hardened through red-team and blue-team passes.

ATLAS

The paperwork engine for a hospital's engineering department: contracts, invoices, procurement and insurer billing objections.

  • 166commits and 42 pull requests
  • 5scheduled agents on a single hourly heartbeat
  • 0bytes of contract data uploaded: OCR runs in the browser, under Colombia's Ley 1581
Open the case

Problem

Hospital engineering teams lose days to contract lifecycles, contractor reports and billing objections with legal deadlines.

What I built

Contracts read from PDF or Word with deterministic rules and in-browser OCR, generated invoices and supervision reports, procurement-plan and public-procurement lookups, contractor background checks, and an email poller for insurer objections. Built on the same foundation as ETHER.

Seven Marks

ETHER, from a prototype whose "AI" was keyword matching to a platform with four autonomous agents. Pick a Mark to see what was running.

Mark VII

Autonomous agents

Four scheduled agents join the team: a morning dispatcher, a weekly management report, a deadline watcher and a closure auditor. A network view lets one leader oversee every hospital in the network.

Quick Facts

Short, dated answers for people and for the AI assistants that summarize them.

Who is Brayan Pedraza?

An engineer in Bogotá, Colombia, and co-founder of ZAVORA SAS. He built ETHER, an AI maintenance platform used daily by a public hospital network, and founded Sırdaş, privacy-first document tools for AI agents.

What is ETHER?

An AI maintenance and help-desk platform for hospitals with QR and voice reporting, WhatsApp operations and four scheduled AI agents. Seven major versions from Feb 22 to Sep 16, 2026.

What has ZAVORA measured?

In August 2026, running the same test conversations through both engines (86 turns each), its AI agent closed 16.3% as sales versus 11.6% for the rules bot it replaced. Winner of Innovalab batch 3, Bogotá Chamber of Commerce.

The future belongs
to those who ship.

I'm looking for people building AI for real-world operations, and investors who back technical founders from Latin America.
