Brodie.

A personal coach in your texts. No app to open.

Brodie lives in iMessage. It remembers every lift, fixes your form from the video you already film, writes your programming, and texts first when you ghost the gym. Coaching that adapts to the individual instead of the average.

The hard parts are pose analysis that finds the exact rep your form broke down, memory that holds months of training context, and a coach that earns trust one text at a time. I'm treating the body the way modern tooling treats code — instrumented, diff-able, improvable.

  • 01

    Form from video

    Pose analysis on a phone clip. The rep where form broke down, and the cue to fix it next set.

  • 02

    Long memory

    Every lift, PR, and constraint remembered. Programming written for you, not the average.

  • 03

    Texts first

    Lives in iMessage. Reaches out when you go quiet — no app, no dashboard.

Technical proof

Kaggle Silver Medal.

Top-percentile finish in LLM 20 Questions, an open Kaggle competition against a global field of researchers and practitioners.

Won by getting the modeling, validation, and engineering details right — not by scale. The kind of result that comes from caring about the tenth decimal place and the shape of the data, not just the headline metric.

Research

Computational Memory Lab, UPenn.

Applied ML and systems work under Dr. Michael J. Kahana.

Built an automated annotation framework for continuous EEG and speech, pushing onset detection toward sub-millisecond precision with WhisperX and adaptive thresholding. Engineered closed-loop Unity experiments that deliver stimuli at EEG-predicted moments of high memory encoding.

Real research code, real subjects, real timing budgets.

Thesis

The interesting problems left are the ones where models meet the physical world and have to be right. I build at that boundary — vision, signal, feedback — and I ship.
