Engineering

i like to build things.

Next Build

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."

on-target inference profiling.

embedded inference pipeline.

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?"

model eval.

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

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?"

odometry & transforms.

ROS2 transform trees and odometry.

coordinate frames and transforms for ROS-based mobile robots.

Inevitable

augmented reality.

more energy.
