Python & TypeScript
My everyday languages for servers, scripts and web.
I build things
that think.
I’m Mateo — I design and build AI assistants, web apps and tools for music and study. Here you’ll find my projects and what I learn along the way.

01 / What I doFour fields
Ideas in.
Working
software out.
From the first sketch to something I use every day — and the write-up afterwards.
S/01
AI & agents
Personal assistants, MCP servers and tools that let language models act safely in the real world — with approvals where it matters.
See projects
S/02
Web & apps
Fast websites, dashboards and iPhone and Mac apps — designed with care and built to be used every day.
See projects
S/03
Music & audio
Tools for musicians: live in-ear mixing from the keyboard, system-wide EQ and DAW automation.
See projects
S/04
Self-hosting
My own home server with Docker, reverse proxy and backups — services I run myself instead of renting.

03 / ProcessHow I work
From annoyance
to tool.
- 01
Notice
Most of my projects start with something that annoys me in everyday life — at ETH, on stage or at my desk.
- 02
Prototype
A rough version in a day or two. Good enough to find out if the idea is worth more time.
- 03
Build
Then properly: tests, security, a clean interface — and the details that make it pleasant to use.
- 04
Ship & share
I use it myself every day, fix what breaks and write about what I learned on the blog.
04 / About meWho’s behind this
Student.
Builder.
Musician.
I study computer science at ETH Zürich. Next to lectures I build the tools I wish existed — and on weekends I play drums and bass on stage.
05 / ToolboxWhat I build with
My
toolbox.
Swift
Native iPhone and Mac apps, menu bar tools and Core Audio.
Claude & LLMs
Agents, tool use, MCP and local models on my own AI server.
Docker & Linux
Containers, reverse proxies and backups on my home server.
Supabase & Vercel
Databases, auth and hosting for web projects like this one.
Audio & video
FL Studio, DaVinci Resolve and the drums and bass on stage.
