Mattia Metiu

I have been building software since I was twelve. Today I work across several projects at once, and film part of the process on YouTube.

Background

  1. Age 12

    Parlot

    My first real project: a voice agent for the PC. It listened, understood a spoken command and acted on the machine. Written in Python, entirely by hand — back then there was no model to write it for me. There is a video of it running.

  2. Age 14

    PiramidKid

    My first published video game, an adventure released on Google Play. Designed, built and shipped on my own — the first thing I made that anyone could download.

  3. 2025

    YouTube channel

    Started @metiu-tek, where I show what I am building and how it actually works.

  4. 2026

    Several projects at once

    Local AI platforms, model compression, browser tools for 3D printing, video automation. Alongside that I am starting my first collaborations on YouTube, and my first work on real projects with other people.

What I do

Development
Python, C#, C++ and the web stack — HTML, CSS, JavaScript. Desktop tools, web apps, agents and command-line software, built end to end.
3D modelling
Parametric modelling in FreeCAD, from a measurement to a part ready for the printer.
3D printing
Not just the model: calibration, materials, and fixing the prints that come out wrong.
Blender
VFX and 3D animation: scenes, motion, compositing and rendering.
Video editing
Cutting, sound, colour and the finishing that turns raw footage into a piece worth watching.
Graphics
Thumbnails, covers and the small pieces of visual design a project needs to be seen.
Electronics
Arduino and microcontrollers — the side where software has to meet a physical circuit.
Machine learning
Building neural networks from scratch — classifiers, linear and non-linear regression — and adapting existing ones through distillation, fine-tuning and LoRA.

Write to me here — an idea, a problem worth solving, or work you want done. GitHub, X and a direct message on Instagram work too.

Pitch me something

An idea, a tool that should exist, a problem worth solving. Everything gets read, but the pile is long — an answer can take weeks.

Want yours read first? The runner is at the top of the page. Get to 5000 m and this card changes.

Goes straight to me. Nothing is stored here.
