Design that moves
Drag the points: this is how every animation on this site feels before it exists.

Code in motion.
I’m Pablo Sepúlveda. I design and build complete web products, from the database to the last detail of motion, and I leave them up and running on the internet.

I build whole products: the database, the API, the interface and every detail of motion. I ship them fast, accessible and tracker-free, so anyone can use them without reading a manual.
From idea to the internet
I design it, code it
and ship it
Every project goes through the same three steps. Play with them: they aren’t illustrations.
$ npm test
✓ damage formulas match Showdown
✓ loop guard keeps line numbers
✓ solution passes, starter fails
✓ site links, titles and alt text
pass 128 · fail 0
Code that gets tested
If a formula, a link or a challenge fails its tests, it doesn’t ship.

01Web product · 2026 Live
Pokédex.cl
The Pokédex in Spanish, made in Chile: all 1,025 Pokémon, a daily challenge, eight minigames, battle tools and a trading card section with collections, trades and prices.

The hard part
Formulas that don’t lie
Damage and stat formulas are tested against Pokémon Showdown on every release; if one differs, it doesn’t ship.

02Web product · 2026 Live
intenta.cl
An HTML, CSS, JavaScript and Python playground in Spanish for teaching programming: challenges with tests, live classrooms in stages and a collaborative whiteboard.

The hard part
Infinite loops
Before running, the JS is parsed with Lezer and every for/while gets a guard on the same line: line numbers don’t change and the loop is cut off after 1.5 s.

CápsulasDev
A platform for learning to code in Spanish with 19 hands-on tracks, plus its Android app with Capi as your guide.

The hard part
Never lose, never duplicate
Every position travels with a uid; a unique index means resending never duplicates, and the device only deletes what the server has confirmed.

Colaboremos
Simple technology for neighborhood businesses: the corner store, hair salon or repair shop tells us what’s hard, and we set up the tool that helps, for free and side by side.

1minute is all the business quiz takes
The hard part
For people who aren’t digital
The language, the large type and the “we’ll call you” button matter more than any effect: every screen was written the way you’d explain it to your neighbor.

Artificial life in the browser: five pattern-formation models, from Turing to Lenia, computed on the GPU.

Phase map
The grid is split into about forty tiles, each running its own simulation with its own F and k: Pearson’s boundaries aren’t drawn, they emerge.

About me
Hi, I’m Pablo
I started with Python in 2023 and never stopped: websites, APIs, mobile apps, GPU labs, a video game and data analysis. Today almost everything I make ends up published, with people using it.
I care about things working without asking for more than they need: no accounts when they aren’t needed, no ads, no tracking cookies, and motion that always helps you understand, never distracts.

Shall we build
something?
