Side quests

2 projects · 2026

Two personal projects: a padel app shipped to both stores and a gamified DevOps training site.

QUEST 01 · 2026

NetWork Nation

A padel community app on the App Store and Google Play: rankings, Elo ratings, tournaments, leagues and court booking.

Built and shipped end to end as a side project: an Expo and React Native app, a Supabase backend and an admin console, with Stripe payments, push notifications, stories, reels and direct messages. Released on both stores and updated over the air.

  • Expo SDK 55, React Native 0.83, React 19 and TypeScript on Supabase: Postgres with 350+ migrations, 30+ Deno edge functions and pgTAP tests
  • EAS Build and Submit to both stores with remote version management; every push to main publishes an over-the-air update to a preview channel
  • Path-filtered CI: type checks and a Jest suite of 1,300+ test files for the app, Deno tests for the edge functions, SQL suites against a fresh database, and a guard that keeps Stripe secrets out of client code
  • Ten scheduled GitHub Actions workflows drive and back up the backend's cron jobs: push dispatch every five minutes, daily ranking snapshots, reminders, expiries and purges
  • Stripe Connect payments, in-app purchases, Apple and Google sign-in; the marketing site is prerendered and served by GitHub Pages on a custom domain

QUEST 02 · 2026

DevOpsJourney

A gamified, AI-adaptive DevOps training site built around incidents at a fictional fintech.

A gamified DevOps training site where every lesson is an incident at NimbusPay, a fictional fintech where things break in educational ways. A placement quiz and an Elo-style rating adapt the difficulty to you; it runs as a PWA with no backend.

  • 10 subjects, 190 hand-crafted challenges, from Linux and Git to Kubernetes, Terraform, AWS and observability
  • 5 interaction types, including type-the-command graded by regex and spot-the-bug
  • Rookie → Operator → Engineer → Architect ladder; spaced repetition (SM-2 lite); XP, 40 tier badges, 17 achievements
  • Daily Incident of the Day with an email workflow
  • Optional AI mentor (bring your own key) with answers graded by Claude; works offline, progress in localStorage
  • TypeScript
  • PWA

About

1990s → 2026

My first operating system was DOS, and I played Dangerous Dave and Golden Axe from floppy disks. I grew up alongside the personal computer, close enough to the metal to want to know what ran underneath.

That is still what the work is. Fourteen years in software: a web developer in Cozumel, then support, test automation, an automation team to lead, the only DevOps engineer for two development teams, and now DevOps at Harmonic. I hold a B.Sc. in Software Engineering from SCE. The thread through all of it is the same: build the machinery so the people writing the code can stop thinking about it.

At work I commit to the place I’m at. I get along with people, and I bring good vibes and a respectful attitude to every team.

The sound of a mechanical keyboard is still the sound of my childhood.
