01 / About

Hi, I'm David.

I'm a full-stack web developer. By day I build a travel site with Angular and Node: server-rendered pages, the APIs behind them and the tests that keep them honest.

I work AI-first. I write the spec, direct the coding agents, and review every change myself before it ships.

How I work

• Analysis before code. I compare the options first, then build the one that wins.
• Why, until the root cause. I'd rather say "I'm lost" than ship a fix I don't understand.
• Write it down. Every project of mine has one guide that could rebuild it from zero.

Every day

• TypeScript
• Angular
• Node.js
• MongoDB
• Redis

Also in my toolbox

• Next.js
• PostgreSQL
• Prisma
• Docker
• Java
• Three.js

02 / Work

My day job

I work on the growth team of an online travel company. Some of what I've done there:

• A travel site, rendered on the server

  Angular SSR so pages load fast and search engines can read them.

• An editor for marketing pages

  Versions, scheduled publishing and safe previews, plus the test suite that guards it.

• AI in the team's workflow

  Specs, quality gates and review skills, so coding agents ship code we can trust.

• A RAG proof of concept

  Two ways to answer questions over documents, compared by cost, speed and quality.

03 / Projects

Built after hours

• gymapp

  An app for gyms: routines, a workout player, classes and payments, for members, coaches and admins.

  Next.js · Prisma · PostgreSQL · Redis

• My own cloud

  One server that runs everything I make: deploys from GitHub, HTTPS, monitoring and alerts on Telegram.

  Ubuntu · Docker · Coolify · GitHub Actions

• My own AI agent

  A self-hosted agent I talk to on Telegram, with one profile for my career and one for me.

  Hermes Agent · Docker

• This room

  A 3D scene that turns into a bachata party when you press play.

  Three.js · WebGL shaders

04 / Life

Away from the keyboard

• Bachata

  Classes and socials. The goal: feel the music instead of counting steps.

• Anime

  One Piece first. Yes, all of it.

• The gym

  Discipline you can measure. It's why I built gymapp.

• Math for 3D

  Learning trigonometry to write my own 3D renderer in a terminal.

• Philosophy

  Existentialism and a daily memento mori.

• English

  Practicing every day. This page is part of the homework.
