portfolio
software, simulations, and interactive graphics.
01 · production systems
Migrated an internal financial reporting platform to Tabular with zero downtime, owning implementation, telemetry, validation, and operational support.
Owned Tableau analytics products for institutional stakeholders from discovery through implementation, deployment, and ongoing support.
python · mujoco · control systems
six-legged robot simulation and control experiments.
PPO learns joint corrections and gait cadence for a six-legged MuJoCo robot. walk_fast_500 reaches 0.888 m/s in the recorded mean-policy run, with no falls across 24 fixed flat-ground evaluations.
scope: flat-ground walking; foot slip remains.
view work ↗python · pytorch · tokenization · attention
tokenization, language modeling, and causal attention in pytorch.
pinned notebook records cover a tokenizer, a trained bigram baseline, and an attention block; the current source extends the study with transformer comparisons.
recorded notebook metrics are pinned at 19222f1; the current study continues beyond the bigram baseline.
view work ↗python · duckdb · dbt · flask
tournament data, player ratings, and a nightly pipeline.
tournament results feed a nightly duckdb/dbt pipeline with glicko-2 ratings. the dashboard validates shadow-database rebuilds before promotion, with a direct-write fallback. its experimental deck estimates use bayesian shrinkage and approximate 90% model intervals that exclude baseline uncertainty and dependence between cards.
view work ↗typescript · canvas 2d · fourier analysis
interactive fourier reconstruction of drawn curves.
drawn 2d curves are reconstructed with rotating vectors. the interface exposes the periodic seam and normalized rms reconstruction error.
error is measured against the input curve.
view work ↗three.js · webgl2 · shaders · web audio
audio-reactive webgl jellyfish.
procedural mantle, filaments, oral arms, and accretion disk. local files or captured tab audio drive the full application, with separate playback and visual-intensity controls.
the black-hole lensing is an artistic approximation. the homepage specimen is silent; the full app responds to audio.
view work ↗semantic typography · three.js
a searchable lyric-sheet reader with focus mode and song comments.
plain-text lyrics sit over a webgl color field, with a focused reading view and a separate panel for public Genius comments. the text remains usable without webgl.
view work ↗React · SQLite · MCP
a shared drawing wall for leaving and curating marks.
the React client and MCP tools work with a SQLite-backed wall, keeping the public surface and its curation record in the same project.
open mural ↗tauri · svelte · windows
keyboard-controlled spotify desktop client for windows.
saved tracks, playlists, search, playback, and queue editing in a native desktop app. it ships as an nsis installer and stores tokens in windows credential manager.
view work ↗typescript · websockets · sqlite · canvas
server-owned artificial-life simulation.
feeding, reproduction, energy budgets, and inherited mutations. websocket clients share one simulation. sqlite snapshots preserve the world and random-number state for deterministic resumption.
simulation behavior has not been validated against real ecosystems.
view work ↗three.js · web audio · spatial interaction
audio-reactive 3d corridor.
estimated tempo controls travel speed. frequency bands shape the visual field, stereo width expands it, and detected attacks trigger decaying pulses.
tab-audio capture is implemented; sample audio requires a configured source. spotify authorization is implemented separately from the visual signal path.
view work ↗three.js · web audio · typescript
audio-reactive nebulae, dust, and light.
local tracks, microphone input, or captured browser audio drive accretion fields, nebular dust, light echoes, and jets. the audio analysis stays in your browser.
view work ↗youtube · generative weather
a youtube player with changing weather.
an authored weather timeline follows the playback clock. seeded climates combine skies, clouds, mist, rain, particles, and electricity around the player.
the weather follows timing and metadata presets. it doesn’t analyze youtube’s audio.
view work ↗spatial interface · code visualization
spatial codebase viewer.
files are cubes, functions sit inside them, and variables are voxels. you can drag and dock them, inspect weighted connections, and change the spatial mapping.
view work ↗python · pandas · seaborn
census-tract analysis of social vulnerability and health.
the recorded notebook joins 78,815 census tracts and compares overall social vulnerability and four theme rankings with six selected health measures. outputs include a correlation heatmap, a diabetes scatterplot, and state-level correlations.
these are observational relationships. they don’t establish causation.
view work ↗python · numerical methods
numerical-method exercises and notebook drafts.
laplace relaxation, sheet gravity, and lattice sums. recorded outputs include relaxation plots and naive-versus-vectorized lattice-sum timings; some exercises remain unfinished.
view work ↗deterministic physics · webmcp
a physics experiment a person or a browser agent can run.
a deterministic ramp simulation with five webmcp tools. the tools use the same controls and measurements as the browser interface.
the full natural-language agent loop still needs validation.
view work ↗p5.js · webgl · material studies
botanical sketches and an interactive 3d bouquet.
a p5.js lily sketch and a three.js bouquet with growing stems, opening petals, and a flower-and-color picker. earlier image-reveal studies remain in the repository.
the current bouquet uses procedural geometry and shaders; earlier image-reveal studies use generated material.
view work ↗02 · Current engineering study
controlled MuJoCo experiments and a six-legged robot with preserved standing and learned walking checkpoints.
MuJoCo experiments in feedback, coupled dynamics, model-based control, and jacobian mappings.
a six-legged MuJoCo robot with recorded native PPO walking and preserved historical browser checkpoints.
03 · Selected work
an analysis of social vulnerability and six selected health measures, with 78,815 joined census tracts in the recorded notebook.
A competitive Pokémon TCG analytics platform that uses a DuckDB and dbt pipeline to produce live rankings, meta analysis, and matchup estimates.
A minimal Windows Spotify player inspired by ncspot ↗. It supports native playback and keyboard navigation.
