My signature
I make digital things feel good in your hands

Every action responds instantly and has just the right weight, like a good game.
Technical detail

I care about how every action feels: it responds instantly, has just the right weight and never jumps. Like a good video game, even on a serious website.
- I design how a product feels, not just how it looks: instant response, anticipation, weight, inertia and settling, with no teleporting or jumps.
- Motion curves and measured juice The small touches of motion, sound or light that make an action land and make you want to do it again.: just enough for the action to read, no decoration, with visual and haptic feedback.
- Characters with believable behaviour: states, attention (watching the cursor), rest, curiosity and response to direct handling (grab, throw).
- Reviews by specialised game feel How good it feels to handle something: it responds instantly, has just the right weight, and every gesture gets an answer. and animation auditors, with film and video-game criteria, for every new mechanic.
- The same on the web as in 3D, with interfaces you handle like a physical object, on phones too and respecting “reduce motion”.
- The proof is on this very home page: MANCA, my virtual assistant, lives camouflaged in it.
Feel the difference

Drag and throw each ball. With the keyboard: arrow keys to push it.

Without game feel

With game feel
I design games and make them playable

Clear mechanics and lively characters, from the idea to something you can play.
Technical detail

From the idea to a prototype you can play: clear mechanics and rules, and characters that react naturally, tuned until they're fun and easy to read, on phones too.
- Godot 4 A free, open-source game engine. (GDScript): characters with activity-level behaviour and procedural animation Motion calculated on the fly from what's happening, instead of being drawn frame by frame., reviewed by animation auditors.
- Art direction from references, model viewers for sign-off before integration, and silhouette and readability reviews on small screens.
I create 3D experiences in the browser

3D worlds that open from a link and move with believable physics.
Technical detail

Interactive 3D worlds that open from a link, nothing to install, with believable physics and smooth on phones too.
- three.js The most widely used library for drawing 3D in the browser. with BVH A way of organising 3D geometry to find out very quickly what collides with what. collisions and Rapier A fast physics engine: gravity, collisions, objects you can pick up and throw. physics (WebAssembly Compiled code that runs in the browser almost as fast as an installed program.): grabbing, throwing and structures you can move through.
- Multiplayer with an authoritative server In an online game, the server decides what really happens, so nobody can cheat from their own computer. over WebSocket An always-open connection between browser and server so they can exchange data instantly. and the same simulation on client and server.
- Performance: a fixed frame-rate target, automatic measurement and hunting down hitches and flicker.
- Carefully tuned feel: easing, weight, settling and first-person camera, with no jumps or duplicates.
- Worlds defined as data (components, catalogues and styles in YAML A simple text format for data and settings that both people and programs read easily.) and tile-based building.
I build complete web and mobile apps

Apps that install, send notifications, work offline and stay in sync.
Technical detail

From the server to your phone screen: apps that install, send notifications, work offline and sync across your devices.
- TypeScript JavaScript with types: the computer flags many mistakes before they ever reach people. end to end: Node The most common way to run JavaScript on a server, outside the browser. (Fastify, WebSocket, native SQLite), React The most widely used library for building web app interfaces. and Vite A tool that bundles a website's code so it loads fast..
- Installable PWA A website you can install on your phone like an app, without going through an app store. with Workbox, Web Push Phone or desktop notifications sent by a website, even when it's closed. notifications and offline support.
- OAuth The secure “Sign in with…”: you grant an app access without giving it your password. integrations with Google services and real-time sync across devices.
- Infrastructure at the edge Servers spread around the world, close to each visitor, so everything responds fast. on Cloudflare A company with servers all over the world that hosts websites and protects them from attacks. (Workers, D1, Turnstile, tunnels) and private networks with Tailscale A private network between your own devices, to connect them securely without exposing them to the internet..
- Learning algorithms such as spaced repetition (FSRS An algorithm that works out the best moment to review something so you don't forget it.), with tests.
I take ideas into production

Pieces that fit and independent reviews: fast, without cutting corners on quality.
Technical detail

I decide what matters, build it in pieces that fit together, and nothing is done until an independent review says so. I work like a small studio.
- Clear rules first: the language between pieces (TypeScript types JavaScript with types: the computer flags many mistakes before they ever reach people. plus a changelog that only adds and never breaks) is set before the work is split up.
- Parallel work, each part on its own branch (a git worktree A separate working copy of the same project, so each part can move forward without stepping on the others.) with a shared status log.
- Independent reviews that don't see the maker's reasoning (UX/UI User experience (UX) and user interface (UI): making an app easy to understand, comfortable to use and good-looking., game feel, animation, art, accessibility, security, licensing), looping until no serious or medium issues remain.
- Living documentation: every decision with its recommendation, plus version and design logs.
I deliver quality: tested, accessible and secure

Tested, accessible to everyone and careful with your data.
Technical detail

What I deliver is tested, anyone can use it (including with a screen reader or keyboard only) and it looks after people's data.
- Automated tests: Vitest, node:test and Playwright A tool that drives a real browser to test a website the way a person would., including end-to-end tests with several clients.
- WCAG AA The international web accessibility guidelines; level AA is what European law requires. accessibility and UX/UI User experience (UX) and user interface (UI): making an app easy to understand, comfortable to use and good-looking. audits, mobile first.
- Security and privacy by design: nothing exposed that doesn't need to be, per-device permissions, layered anti-spam and GDPR The European Union's General Data Protection Regulation..
- Third-party licences checked (fonts, music, CC BY-SA An open licence: you can use the material if you credit the author and share yours under the same licence. data) before publishing.
- Windows desktop automation: start with the system, self-recovery and hardware controller integration.
I think about who will use it

From day one, I think about who will use it.
Technical detail

I don't stop at the prototype: from day one I think about who will use it and how it can stand on its own as a product.
- Product and business vision: from prototype to something you can sell.
- Priorities set with both the user and the buyer in mind.
