Independent builds. Reverse engineering, computer vision, and a healthy disrespect for "there's no API for that."

01 · Developer Tooling

Tableau Interactor

Programmatic chart authoring for Tableau Cloud, a platform with no official authoring API.

Tableau Cloud fires internal VizQL wire commands on every click and drag. I reverse-engineered that protocol and built a Python bridge that authors worksheets and dashboards entirely in code. It ships as an MIT-licensed Claude Code plugin: describe a chart in plain English and it's built live in your signed-in session.

  • Locates Tableau's in-page command dispatcher by behavioral signature, so the bridge survives minified-code rotation across releases
  • ~90 typed Python primitives across the authoring surface: marks, calculated fields, seven filter types, analytics objects, and dashboard composition with cross-filter wiring
  • Traced the SPA's deferred-response queue to force sub-500 ms re-renders after each wire mutation, replacing a ~3 s reload workaround
  • Builds a four-chart, cross-filtered dashboard from code with zero clicks

Apex

An AI strength coach that watches you train, knows your recovery, and diagnoses weak points before prescribing.

Set your phone on a tripod and Apex tracks reps, depth, and tempo with on-device pose estimation. A zero-dependency coaching engine turns real-life signals like sleep, HRV, and daily movement into week-to-week programming, and an assessment phase distinguishes muscles that are genuinely weak from ones that are merely poorly recruited.

  • Zero-dependency, platform-agnostic coaching engine (~300 automated tests) driving full mesocycles: double progression, RIR ramps, volume landmarks, auto-deloads
  • Markerless CV pipeline for rep counting, depth, tempo, and form faults: BlazePose landmarks to joint-angle signals to a hysteresis state machine
  • Signal-driven autoregulation: HealthKit recovery data flexes training volume while deliberately holding load
  • Offline-first Supabase backend with hardened row-level security and debounced cross-device sync
