IbuildsoftwareI'dactuallyusemyself.

Self-taught developer from Barcelona. I fix problems with code, ship the tools I actually want, and stream while I build them.

Work

Selected work.

  • 01InstantClone

    An open-source RTMP delay proxy for live streamers. Arm a buffer, watch it fill in real time, then cut to a clean feed the moment you need it.

  • 02· privateCrossr

    The on-demand script runner that should have existed ten years ago. Write once in CrossrScript, paste a curl on any machine, and watch the output stream live in your browser. One script compiles to bash on Linux and PowerShell on Windows. No agent, no per-device pricing. My biggest project so far.

  • 03onekoPy

    The cat that chases your mouse pointer, rebuilt in Python with a few extra moods and modes. A small, playful take on a desktop classic.

    PythonTkinter
  • 04stream-ads

    A tool for my streams. Viewers send in joke ads, I pick the good ones, and they play as an overlay live on stream.

  • 05csApp

    Reactive lighting for your desk. It listens to live CS:GO game state and drives the LEDs on your keyboard, mouse, and other devices. Outdated since cs2 release.

    C#.NET
  • 06MY_VOID

    A storefront for a minimalist clothing label, built end to end. Stripe checkout, custom shipping logic, and a catalog that stays out of its own way. Was a limited time store.

    Next.jsStripeTypeScript
  • 07Tokes

    A real-time encouragement app. Friends send short notes that arrive instantly over WebSockets, with live presence and push-style notifications. Was a nice way to learn. Never released.

  • 08Java-ASCIITree

    A small generator that grows dynamic ASCII tree art from a handful of parameters. An early experiment in procedural shapes. Made as a school project.

Self-taught and based in Barcelona. Most of what I make lives in private repos and client work, so this is only a slice.
