5000 m Now it is your turn.
You got past every bug, error and failed print on the way here. So pitch me something: an idea, a tool that should exist, a problem worth solving. If it is good, I will write back and we build it together.

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
-
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.

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.

2025
YouTube channel
Started @metiu-tek, where I show what I am building and how it actually works.

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.
Projects
- Vortelio Local AI platform: language models, image generation, speech and TTS offline, in one binary. Go
- tube-assistant Autonomous video pipeline — script, voice, editing, thumbnail and upload, controlled from Telegram. Python
- prune_lab Pruning and 4-bit quantization that fit 200B-parameter models onto consumer hardware. Python
- lithophane-studio Turns a photograph into a 3D-printable STL, entirely in the browser. JavaScript
- rvm-web Video background removal without a green screen, served as a web app. Python
- acf-agent-format A compact wire format for agent tool calls: 46% fewer tokens than compact JSON. Python
