Value proposition
What I solve
I bring product, design and frontend problems into focus, then turn them into clear interfaces and code the team can maintain.
I bring frontend experience and technical judgement to frame product problems and carry them from definition to a solution the team can maintain. I work across product, design and technology to build clear interfaces and explicit architectures, while helping teams evolve the product.
Process
How I work
A process for understanding the problem, aligning decisions and delivering changes the team can maintain.
Systems
Architecture
I have contributed to the design and evolution of frontend architectures for applications with complex business logic, service integration, testing, continuous integration and distributed teams. I prioritise clear boundaries, explicit data and components the team can understand and change.Technology
Stack
My main foundation is JavaScript, HTML and CSS, with experience in Ember, LitElement, SCSS, frontend tooling, testing, Git, CI and REST APIs. I also bring a solid PHP, SQL and management applications background, useful for understanding product beyond the visual layer.Experience

Personal and family project
Jucart
Product, frontend architecture and AI-assisted development
Jucart started as a private shopping list to replace the whiteboard on the fridge: add products and cross them off without friction. From that small need it grew in layers: offline use for shopping, Supabase to share it across devices and a ticket inbox that Codex processes to extract lines and build price history. The tool keeps a simple interface while adding automation and price history.Social product in production
Music Bingo
Product, full-stack architecture and real-time experience
Mobile web app for running in-person music bingo games. Hosts import songs from text, CSV or Spotify, share a code or QR, and announce each track; players use digital cards on their phones. Convex holds shared game state and validates marks, lines and bingo claims. Spotify can control playback when an account is connected, while the music itself plays outside the app.Local and community digital platform
Palomares del Campo
Product, full-stack architecture and frontend development
Editorial website and interactive experiences for Palomares del Campo. News, municipal notices and routes are generated as static pages; Leaflet and OpenStreetMap provide maps and GPX routes, while Three.js scenes load on demand with a fallback. Convex provides remote state for a geolocated game and moderated “Palomareños por el mundo” submissions, without making editorial content depend on the backend.Municipal coat of arms: Asqueladd (CC BY-SA 3.0)Beyond work
Another way of looking
I am a drone enthusiast.
Planning a flight, finding a perspective and turning it into an audiovisual piece is another way of working with attention, precision and curiosity.
