we taught magic sand to do linear algebra and now it can think (maybe)

"went from ai agnostic to ai religious" - people after talking to me

Hi! I am Maksym, currently working on AI for mechanical and electrical engineering at a startup in San Francisco. Previously a Computer Engineering student at Columbia University (John Jay Scholar, Neo Scholar), born and grew up in Kyiv, Ukraine.

I am passionate about AI, hardware, startups and deep tech.

Previously, I have started Pravopysnyk, AI grammar correction service for Ukrainian, published research, and worked on cool hardware projects.

In parallel working on Danish Bricks Builder, the first (and the best) place to vibecode a LEGO set.

Explorations

Danish Bricks Builder

teaching AI to build with LEGO bricks

2026 · research/product

building data, models and benchmarks to enable AI to do mechanical engineering, using LEGO bricks. we have the best AI LEGO builder in the world: it turns any prompt into a validated LEGO set you can build TODAY.

CAD Arena

llm arena, but for CAD

2025 · research

open benchmark for AI-generated parametric CAD inspired by LLM arena, comparing commercial and academic models.

Paperfan

strava/goodreads for research papers

2025 · product

we ingested and embedded all of arxiv (~2.5M papers), so it’s easier to find new papers to read and keep track of the ones you’ve already read.

Trot or Rot

building a robot dog

2024 · robotics

building a Dingo-style quadruped from scratch: designed it in Fusion360, simulated it in PyBullet, then taught it to walk with reinforcement learning and ran that on the real robot. Unfortunately many robot legs were harmed in the process.

2020–2024 · startup

The first AI grammar correction service for Ukrainian. Won 1st place in the GEC+Fluency track of the UNLP 2023 shared task, with a paper at the UNLP workshop at EACL 2023.
