I'm a Chrome extension developer and visual designer based in Girona, Spain. I spent years running Projekta2 Creative Studio — immersive web experiences where design and engineering were indistinguishable. That background shapes everything I ship.
I build tools for the third week of use — when the novelty is gone and all that's left is whether it saves you time.
What makes my tools different:
| Principle | What it means |
|---|---|
| 💳 One-time payment | You pay once. You own it forever. No subscription tax for features that shouldn't recur. |
| 🔑 BYOK — Bring Your Own Key | Your API keys never leave your machine. Zero backend proxy. Zero data collection. |
| 🌍 Bilingual from day one | EN/ES built into the i18n architecture — not translated after the fact. |
| 🚫 Zero telemetry | Not even error reporting unless you explicitly opt in. |
| 🌗 Real dark mode | Every extension ships with dark mode from v1. Not a checkbox — a design decision. |
All extensions share the same philosophy: one-time payment, 100% local processing, bilingual UX (EN/ES), no telemetry, no dark patterns.

Clients — All three extensions are live and free to install. The best way to evaluate my work is to use it. Custom Chrome extension development available on request — bring a problem, I'll build the tool. Employers / freelance — Unusual combination in the market: production-level visual design + working knowledge of Chrome Extension APIs, AI integration (BYOK, prompt engineering), DOM extraction, Google Sheets API, and JavaScript from scratch. I care about UX that doesn't need a tutorial. Open-source community — PR Review Canvas and Build Logs are both actively maintained and open to contributions. If you want to make your first open-source contribution, there are good first issues waiting.
