Software engineer in Madrid.
I design and maintain full-stack apps, Python tooling with tens of thousands of installs and published Android apps. I currently act as DevOps for my team.
I build CLIs and services, automate processes and keep my own libraries alive. I also make video games as Lianes8 Studio, on an engine I wrote, and set up CI/CD pipelines.
Rhythm arena survivor / roguelite
Rhythm arena survivor where each song's lyrics drive the run: every line fires a different effect. The engine parses LRC files in real time and players upload their own songs through Steam Workshop.
Chill incremental / idle (cozy pickpocket sim)
A chill heist incremental: a flock of pigeons picks the pockets of a city park, and the stolen coins pay for a big upgrade tree.
Incremental / idle (kawaii fortune shrine)
Pet the cat, spin the slots, earn your luck.
Game engine · Private
The engine my games are built on: TypeScript on Pixi v8, a deterministic fixed-step simulation, audio, input and saves, Steam and Android builds, and a translation pipeline for Steam's 31 languages.
From libraries and games to production apps.
Tool · Python · PyPI
Analyzes an OpenAPI/Swagger spec and catches REST design mistakes before they reach production. An ecosystem with a PyPI CLI, a backend-less web app, a FastAPI API and a multi-language landing. Drops into CI/CD with a single pip install.
Tool · Python · PyPI
Compares two JSON documents and produces a visual HTML report of the differences. Useful for audits, migrations and API debugging.
Android · Kotlin
Birthday reminder that syncs with Google and schedules notifications with personalized messages. WorkManager runs daily jobs without draining the battery.
FiniQ, a net salary and severance calculator under Spanish labour rules, was retired from Google Play for lack of time.
Full-Stack · Next.js + FastAPI
Estimates the Madrid taxi fare before you get in: Google Maps routing with offline GraphHopper fallback; the engine applies official fares plus night and holiday surcharges, with route caching on the back.
Full-Stack · Astro/Vue + FastAPI
Football club site with self-updating results, standings and fixtures: a scraper on Azure with scheduled jobs feeds the Astro + Vue front every day.
