Mattia — Metiu

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

   Local-first AI tools

   Vortelio, a local AI platform in one binary. TubeAssistant, a YouTube channel that runs itself. vedit, a video editor an AI can drive. All open source, all running on your own machine. Alongside that, my first collaborations on YouTube and my first work on real projects with other people.

What I do

Development

Go, Python, C# and the web stack — HTML, CSS and JavaScript. Desktop tools, web apps, agents, MCP servers 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 — adapting existing ones through distillation, fine-tuning and LoRA, and running them locally with llama.cpp, diffusers and Whisper.

Projects

• ShowUp building now The one I am on right now. Post a project and find the people who will build it with you — having only an idea is enough to post one. Reliability is not self-declared: the site measures on its own who answers and whose projects actually get finished. Opens when it is ready. TypeScript
• Vortelio Local AI platform: LLMs, Stable Diffusion, Whisper, TTS, video and 3D generation, all offline. An open-source Ollama + ComfyUI alternative in one binary. Go
• TubeAssistant A YouTube channel that runs itself: script, voice, stock clips, editing, thumbnail and upload, every day, on its own. Controlled from Telegram, runs on free tiers. Python
• vedit new Tell an AI to edit your video and watch it happen. A real timeline editor with 77 tools an agent can call over MCP, from Claude Code, Cursor or Codex. Python · React
• llm-tier-router new Stop paying for the big model on easy questions: a ~1 ms classifier that routes each prompt to the cheap or the expensive LLM. 97.6% accuracy, 12k-example dataset included. Python
• rvm-web Cut the background out of a video without a green screen, on your own PC. Real alpha for Premiere, DaVinci and OBS, plus AI upscaling. Python
• lithophane-studio Turn a photo into a 3D print that glows in backlight. Runs in the browser, nothing uploaded, exports print-ready STL and OBJ. JavaScript
• acf-agent-format A compact replacement for JSON in an LLM's context window. Same data, 46% fewer tokens, lossless roundtrip, zero dependencies. Python
