This is how I build a website. Piece by piece, on every screen at once.

I design websites, build them and ship them to production on Cloudflare. Digital product development and applied AI.
01 — Work
Recent projects, from interface to deployment. Hover over each one to inspect it; open it to see it running.
02 — What I do
I define features, interfaces and flows. Clear requirements, priorities and a review of every screen.
React, JavaScript and TypeScript, PHP and SQL. Data, forms, permissions and integrations done properly.
Cloudflare Pages and Workers, D1, R2 and Durable Objects; Git and Docker. Fast, secure and no servers to babysit.
Support for analysis, development, review and documentation, and AI features inside the products themselves.
In-house applications, not publicly available.
Kanban views, tasks, habits and notes. Editors with tags and autosave, with permission reviews.
Documents, amounts, expenses, due dates and payments per project, with data consistency checks.
Drafts, resuming half-finished forms and reviewing submissions through read-only reports.
03 — About
I have been in the trade since 2015: first repairing computers and phones, setting up networks and the odd website at PCClick; then in Madrid, with a WordPress and PrestaShop marketplace, and since 2016 in Grupo SANED's IT department, across systems, web development and video.
I have worked remotely since 2020 and focused on creating and evolving applications: I define features, interfaces, data and integrations with the help of AI, and take them all the way to production. Three things matter to me: that it is clear, that it works on any screen and that it does not fall over.
If you would rather meet me by playing, my CV is also a video game: Sergio Quest ↗ (or type “quest” anywhere on this page)
