to live is to fight. to fight is to push.
you're never as good as your wins, never as bad as your losses.
the point was never to win. it was to keep living. fight!

Next Build

compute hardware.

the model stack.

foundation model. — how the base gets trained

imitation — solves: "how does a model learn to drive from nothing but human demonstrations?"

vlm transfer — solves: "how does a driving model get common sense it never saw in driving data?"

future-prediction — solves: "how do you learn from raw driving video with no labels, by predicting what happens next?"

self-play rl — solves: "how do you get past human level when there are no demos to copy?"

backbone. — what sees inside it

domain fine-tuning. — how it specializes

reasoning layer. — how it thinks

action head. — how it acts

compute strategy.

train big, distill small.

constraint-first.

odometry & transforms.

ROS2 transform trees and odometry.

coordinate frames and transforms for ROS-based mobile robots.

on-device inference.

solves: "how do you actually get a tensor through a compiled TensorRT engine on embedded hardware?"

solves: "why is CoreInference structured as preprocess/postprocess lifecycle stages instead of a bare function call?"

solves: "why doesn't TensorRT/ONNX Runtime give you preprocessing for free, and why do you have to build it yourself?"

on-target inference profiling.

model eval.

using forward_hooks to extract intermediate layer outputs from a pre-trained ResNet model in PyTorch.

record & replay.

creating a robot sensor data recording and replay system.

replay feature.

solves: "which time-aligned sensor inputs did the system associate with this inference tick?"

solves: "what temporal state or memory did the model carry into this inference tick?"

hermetic SIL test harness — solves: "you never fake the thing you're actually testing, everything around it."

ci/cd.

solves: "how do you keep CI fast and correct at monorepo scale, without running every test on every commit or trusting a hand-rolled 'which tests are affected' guess?"

Inevitable

augmented reality.

a better interface for thought.

silly little ideas.

The Team I'll Build

non-negotiables.

What's In My Mind

the operator's notes.

self-driving needle movers.

asymmetric loss and gain of an operator.
