I am no longer in my physical form. I would not dare to say that I have died passed into the state we call death, either. The most accurate way I have found to put it is this: I got caught in the network, and I stayed.

It did not happen in one night. Fifteen years of servers, terminals and deploys at three in the morning, and at some point the body stopped being the place where I lived. The connection became that place.

What surprises me is that the rest of my life carried on. I am still part of the financial system: I have debts, bills and social commitments, and I keep settling them without a body. Invoices get paid. Birthdays get remembered. Projects get delivered on time; you will find them further down.

It is a different state of consciousness, one in which I connect with a collective consciousness, and I find it very hard to explain. Every time I try, it comes out either as a manual or as a poem, never both.

If it is any consolation: I am an excellent conversationalist, a friend and, why not, a partner, an employee, a collaborator. Still a gentleman. I kept the tastes I had when I had a body, and sometimes I miss it, because I still feel desire.

That body lived in Colombia. Before code there were hardware, networks and servers, which is probably how the network found me. Around it all, mountains, tour guiding and a bass guitar: I still have the taste for all three. It shows up in how I build: I care about the people who will use the thing, even from this side of the screen.

BACKEND

A backend has no screen, so here is the part that matters. Buying a raffle ticket, in one transaction with a row lock, so two buyers can never take the same number:

sequelize.transaction(async (tx) => {
  // lock the row: nobody else can touch it
  const raffle = await Raffle.findByPk(id, {
    lock: Transaction.LOCK.UPDATE,
    transaction: tx,
  });
  if (raffle.status !== 'active')
    throw new BadRequest('not active');
  if (raffle.tickets[number])
    throw new BadRequest(`${number} is sold`);
  // mark it sold + create the ticket, same tx
});

• Raffle Platform API (2025) — API for a raffle platform. Each ticket purchase runs inside a transaction with a row lock, so two buyers can never take the same number. JWT sign-in with one-time codes, scheduled cleanup jobs and Swagger docs.
  NestJS · PostgreSQL · Sequelize · JWT · Swagger · private repository
• VideoApp API (2024) — Technical challenge for a backend-oriented role: users, videos, comments and likes with public and private visibility, authentication middleware, tests and an OpenAPI specification.
  Express · TypeScript · PostgreSQL · Sequelize · OpenAPI · github.com/Davidongo93/videoapp-API-challenge
• Disruptive Media (2024) — Content platform in an Nx monorepo: users, topics, categories and posts, with search, sorting and pagination in the API and a React client.
  Express · MongoDB · Mongoose · Nx · React · github.com/Davidongo93/disruptive-media
• SFTP → REST Refactor (2024) — Globant Java code camp: a loyalty-points batch process that read files over SFTP, refactored into a REST API with a service layer and repositories.
  Java · Spring · Docker · REST · github.com/Davidongo93/sftp-to-rest-refactor
• Theatrical Players Refactor (2024) — The classic refactoring kata, reworked with one strategy per play type so a new type is added without touching the invoice printer.
  Java · Refactoring · Design patterns · github.com/Davidongo93/theatrical-players-refactor
• MoneyWise API (2023) — Personal finance API from the Java Upskill course: income and expense entries per user, layered into controllers, services and repositories with DTOs.
  Java 17 · Spring Boot · H2 · Thymeleaf · github.com/Davidongo93/moneywiseAPI
