Sergio Quest.

The brief

A portfolio you can play: my career from Ciudad Real to Madrid told as a pixel-art RPG, in the browser with nothing to install. The rule was to make everything in code: graphics, music and sound, no images or libraries.

Decisions

1. Procedural art and a Web Audio chiptune synth: zero image or sound files.
2. An AI character (Workers AI) that answers questions about my career, with per-IP limits and a daily cap checked before calling the model, so the cost stays predictable.
3. Real-time ghost players with a Durable Object and hibernating WebSockets, in a separate Worker because Pages cannot host Durable Objects.
4. Security from day one: same-origin requests only, IPs stored as salted hashes and speedrun records signed and timed on the server.
5. Bilingual, with a “recruiter mode” for people who only want the CV.

Outcome

In production on Cloudflare Pages, with a guestbook, a speedrun leaderboard, cookie-free anonymous analytics and trailers in Spanish and English.

• Up to 25 players at once, four positions per second.
• The final boss is the hiring process.
