I am Ondrej "iairu" Špánik. I take on one challenge at a time and go deep until it works, so my focus moves with the problem: code one month, a circuit or a 3D model the next, a prompt-driven build after that. What stays constant is the standard: it is finished, it runs, and I understand why.
Loading the NightJar.Gift 3D model…
Design v2This is the current design (Nightjar v2), not a finished bird: nothing has been carved yet, so the real one may still differ.
Drag to turn the bird. Hover the blueprint parts to name them.
No project uses every step. The challenge decides where the work goes deep; the steps are just the order I check them in.
Direct AI like an instrument: specify, test, iterate, and keep the human in charge of the result.
Classic programming: C, Python, JavaScript, Svelte, Astro. Software that is read, tested and kept.
Blender and CAD: shape something in 3D until it can be measured, rendered or cut.
Schematics, boards and firmware, or better no firmware: electronics that fit inside the shape.
CNC, wood, solder. The thing sits on a desk, you press a button and it works.
The full list is ordered the same way, and you can filter it.
Procreate timelapse batch exporter
A GUI that exports timelapse videos from many Procreate files at once, straight from .procreate files or app content. Born from an artist's need to stop exporting one by one. Uses 7-Zip and FFmpeg to extract, stitch and export.
Logic Pro vocal chain plugin
A vocal chain for Logic Pro: resonance, drive, noise gate, pitch, de-esser, three-band EQ, FET compressor, limiter, delay and reverb in one plugin.
CMS that deploys to a static site
A CMS app with extensions that deploys into a static Vercel site, or exports JSON for Gatsby. Includes a collaboration server for editing together.
Prompt-driven port of a file system driver
FUSE driver for Apple's APFS, fixed to build and run on FreeBSD by directing Gemini CLI (Pro model) through the work: a real-world test of prompt engineering on systems code.
First Java project
First Java project from JetBrains Academy plus a few experiments around it.
Cat pedigrees and inbreeding calculator
Helps people find and manage cats and their pedigrees, and calculates the inbreeding coefficient of a pair to judge whether mating is a good idea. Built with Laravel.
Every project was one specific problem, and its field is just what the problem needed. Open a field to see that chapter, or combine two there to see where they met.
LLM workflows, prompt-driven builds, ML experiments.

15 projectsA 3D model became CNC toolpaths, then two halves of beech with a circuit that has no microcontroller and no firmware. Hold the button on its back and it churrs; let go and it sleeps.
Temporary model. The 3D bird above is a stand-in, not the final version of the model.
A logo that must hold up, a story told in letters, a character that has to read at a glance. The graphic design school came before the code, and it still shapes how I build.

Energy drink concept
Tell me what it should do. I will tell you honestly which parts are code, which are copper and which are wood.
