Robosurge Cursor for surgery.

And the best part is we came up with the idea during the Hackathon.

Check out our project here: devpost.com/software/we-...

- Created Nix flakes for reproducible builds on both our production and development environments.
- Used dependent type theory in Lean to prove that trajectories are within safe physical bounds.

- Designed a custom algorithm to convert LIDAR data into 3d coordinates.
- Built a multi-LLM robotic agent using OpenAI's GPT-5.2 and Google DeepMind's Gemini Robotics-ER 1.5.
- Mapped real-time orientation data from a Meta Quest 3 onto a physical moving camera arm.

Came out of a 2 year long hackathon retirement to win 🏆 GRAND PRIZE at TreeHacks 2026 !!!

In 36 hours, we:
- Manufactured, designed, and built an entire 4-armed surgery robot (+ a 6am trip to Home Depot).
- Wrote our own inverse kinematics control system.

Just finished a new blog post! 🎉 👀

This goes into a deep dive into Python's two new type checkers, Pyrefly by Meta and ty by Astral (the team behind uv and ruff)

Heyo, just added an RSS feed! Let me know if you have any feedback on it. (I personally don't use RSS so I don't know what the general conventions are)

Just wrote down 14 of the most interesting Python features that I've come across in my career!

Anyone going to PyCon 2025 👀? (or know of anyone that is going?)

Looking for potential roommates.

Just started a blog!

Been wanting to do this for a while now, but never got the chance to sit down and set it up.

A little empty ATM but hopefully I can get some cool content up in the following weeks.
