This is my personal site, built from scratch with plain HTML and CSS and hosted on Vercel. It covers my classes, projects, and what I do at Sequoia. I also featured the papers I made for data science projects (RunScore and RecovHR). A recent addition was a heatmap for my running. If you click “Cross Country & Track” it opens a heatmap of every run I’ve recorded on my COROS watch.

Hidden pages:
/momrecipe brings you to a collection of my mom’s 345 recipes that I have digitized for her.
/reciptpolaroid was built for a party where you can take a photo on your phone and it will print it on a receipt printer for a makeshift polaroid.
/CalcPlot3D is a self hosted copy of CalcPlot3D because I like it so much I don’t want to lose it.

I built a website for my passion project RunScore! RunScore is a composite index that quantifies the strength of a community’s running culture using public-domain data sources. The index correlates with home values, health outcomes, walkability, and school quality. This makes it a measurable lifestyle signal for home buyers, real estate platforms, and urban planners.

A native iOS app that turns GPX activity files into cinematic 3D flyover videos.

What it does
Import a GPX file from COROS, Garmin, Strava, or any app that exports GPX. RunPath animates a 3D MapKit camera flying along your route and exports it as a polished MP4 video ready to share.

Features
Keyframe timeline editor: Seven animatable tracks, each with independent keyframes and smooth cubic interpolation between them:

Speed 0.1× – 1.9× 1.0 is center of slider
Smoothness 0 – 100%
Camera Altitude 100 – 25 000 m
Camera Tilt 0 – 85°
Line Thickness 1 – 24 pt
Line Color

Stats overlay: Optional run stats burnt into the exported video. Portrait: distance (center, large) + time (left) + pace (right) above a bottom gradient. Landscape: stats stack vertically on the left side with a left-edge gradient.

Export options

Portrait (9:16) or Landscape (16:9)
1080p or 4K
Standard or Satellite/Hybrid Flyover map style
H.264, 30 fps, 8 Mbps
Auto-saves to Photos library
Route library — Swipe left to delete, three-dot menu to rename. Routes persist across launches.

Open-source, catalog-based, non-destructive RAW photo editor (Lightroom-class), GPLv3, 100% local AI. Engine in Rust, one wgpu shader codebase, ONNX Runtime for all ML.

This repo contains the Phase-0 spike + a working Phase-1 (MVP) with a real desktop GUI — proven end-to-end on Apple Silicon (Metal + CoreML):

crates/raw-decode — LibRaw → linear 16-bit RGB + metadata probe, via a stable C-ABI shim.

crates/recipe — serde parametric edit-recipe (sparse, identity-default).

crates/catalog — SQLite catalog: import folders of RAWs (with EXIF), read/write recipes, idempotent.

crates/gpu — wgpu develop pipeline (WB, exposure, contrast,

highlights/shadows/whites/blacks, vibrance/saturation, dehaze, 8-band HSL, post-crop vignette, grain), shared by the live preview and headless export. Preview == export. cargo run -p gpu –example modtest checks the modules.

crates/app — egui desktop app: a Library grid (background-decoded thumbnails) and a Develop view with live sliders driving the GPU pipeline, plus the import / –recipe / –export / –selftest headless CLI.

crates/ai-smoke — ONNX Runtime + CoreML EP smoke test for SAM2.

catalog/schema.sql — full SQLite catalog schema (Task 3).

docs/ — stack decisions, recipe format, develop pipeline, model packaging.

Scripts for organizing family photo collections into a clean, date-based directory structure.

Scripts
create_photo_dirs.sh
Creates a Year/Month folder tree for a given date range.

./create_photo_dirs.sh [root_dir] [start_year] [end_year]

Example: create folders from 2005 to 2024 under ~/Photos

./create_photo_dirs.sh ~/Photos 2005 2024
Output structure:

~/Photos/
2005/
01_January/
02_February/
…
2006/
…
rename_photos.py
Renames photos in a folder to a consistent YYYY-MM-DD_HHMMSS_originalname.ext format. Uses EXIF DateTimeOriginal when available, falls back to file modification time.

Preview changes without renaming

python rename_photos.py ~/Photos/unsorted –dry-run

Rename for real

python rename_photos.py ~/Photos/unsorted
sort_photos_into_dirs.py
Moves (or copies) photos from a flat folder into a Year/Month directory tree automatically.

Preview

python sort_photos_into_dirs.py ~/Downloads/OldPhotos ~/Photos –dry-run

Move files

python sort_photos_into_dirs.py ~/Downloads/OldPhotos ~/Photos

Copy instead of move

python sort_photos_into_dirs.py ~/Downloads/OldPhotos ~/Photos –copy
Requirements
pip install Pillow
Pillow is used to read EXIF data for accurate photo dates. If not installed, all scripts fall back to file modification time.

Typical Workflow
Run create_photo_dirs.sh to build the folder structure.
Run rename_photos.py on your unsorted folder to standardize filenames.
Run sort_photos_into_dirs.py to move everything into the right Year/Month folder.
