2025 to now
ScribbleScan
Handwriting digitization, from capstone to hosted product.
ScribbleScan started as my 2025 capstone and grew into a hosted handwriting-digitization service. It turned handwritten pages into editable documents while keeping images and other non-text elements in place. The hosted service is retired, and the site remains as a demo.

I'm still working on what comes next.
How it grew
The capstone proposal I started from. Some ideas, like the export options, carried through to the end; others, like the target audience and parts of the feature set, changed along the way.
The first working version. It split the results into sections and showed them line by line. It was rough, but it matched the design I had planned.
One day later, with major interface improvements: much larger tiles, and a digitize button that hides once pressed. Both carried into every later version.
A month after the proof of concept: PDF export, copy to clipboard, corrections and accuracy scores. The focus shifted from a demo to a usable tool.
The version I presented for my capstone, adding a per-batch page limit, Google sign-in and a cleaner interface. Not yet a full product, but a finished tool.
After graduating, I worked on ScribbleScan full time, adding user profiles, support, a cloud-hosted database, paid tiers and many smaller features. It was now a complete product.
A week later, I considered it finished. The final addition was a demo mode that let anyone try pre-processed samples of difficult handwriting at no cost to the service.
2022 to now
This website
The site you're on, through four versions and how each one was built.
A hand-coded static layout that grew into an exploratory map.
The map became the website, so you explore pages without opening them.
Handwritten notes pinned to a tabletop, then seven visual themes.
This one, rebuilt on my own design system.
Version 1
December 2022 to June 2023 · 8 snapshots
The first base version of the site. None of the buttons worked yet; the goal was to test the overall idea and color scheme.
At this point I had added working buttons and transitions between pages, as well as a new background image to see the scrolling from the transition effect.
A new background image, used across the whole site.
I wanted the site to feel distinct, so I experimented with an unconventional radial navigation menu that changes from page to page.
Here I had finalized the placement of the menu and menu button (currently a checkbox).
I added the animated menu button along with the old home button, and moved the page links into the new menu and made it functional.
The first working version of the map. In testing with friends and family, the radial menu on its own proved confusing. With the map added, people understood that the menu was taking them somewhere, and it quietly encouraged them to explore the whole site.
Close to the final version of the map and menu. I moved the map to the center of the menu to save space, moved the home button to the top so it's always visible, and added a "current location" marker and names for every discovered location.
Version 2
January 2025 · 6 snapshots
Version 2 had two goals: remove the old map, which was large, slow and broke the mobile experience, and keep the feeling of exploring the site as a place. Instead of a map taking up half the page, the map became the website itself.
A much smaller navigation bar, so the blue is less dominant and the tiles have more room on mobile. The Home button became a house shape.
I changed the background from white paper to sand, for a bit more depth without overwhelming the tiles. The home button moved into the navbar and hides when you are already home.
This is when links were added. The url now changes depending on the tiles viewed, so people can jump straight to what they want to see.
The mini windows became fully functional, opening and closing smoothly. Each one loads a separate page based on the tile selected.
Very close to the finished v2: a back button to navigate the mini windows, and cleaned up versions of all the pages.
Version 3
April to September 2026 · 3 snapshots
v3 threw out the tile grid and replaced it with a wall of handwritten notes pinned to a wood tabletop. Every tile is its own paper scrap, so the wall reads as a real, hand-built collection instead of a generated UI.
Opening a tile slides a cream paper in from the side. The close button turns into a back button when you've gone deeper, and tapping outside the paper closes it: one contextual button, no menu hamburger.
The cream paper now slides up to close, like lifting it off the table, runs larger on desktop, and gets pushed down on mobile so the navbar and close button don't overlap it.
Seven themes
September 8th 2026I kept the same map and rebuilt its visual layer into seven switchable worlds. The difficult part was not adding skins; it was preserving the same navigation, direct links, keyboard behavior and document flow across every theme.

Version 4
November 2026 · 3 snapshots
Version 4 is a notebook. Its cover holds interactive stickers, and opening it leads into the site.
Every story is a page that scrolls, and the wheel on the side turns to the next one. This is the Work page.
On a phone it is one page at a time, with the wheel along the bottom.

NBA Prediction AI
A neural network that called the 2024 playoffs with only 2 mistakes.
Live predictor
Select two teams to make a prediction. Data through May 2024.

- TensorFlow
- Data through May 2024
How it works
A partner project from spring 2024: a convolutional neural network trained on a custom dataset of NBA statistics. We built it in PyTorch, along with a similar version in TensorFlow.
In our testing it predicted wins and losses well, while the exact point differential was harder, as expected. It called the 2024 NBA Playoffs with only 2 mistakes, including several upsets.

Puzzles and models
3D printing
Here are some 3D models I've designed and printed for fun.
I always wanted more puzzle boxes to have around. So I started making them. I bet you can't solve them. Drag any model to turn it.

Shorter games
Gaming
Check out some of my favorite video games! I'll race you in Mario Kart Wii.
When I have free time, video games are another thing I enjoy. I tend to like shorter games, so over the past few years I've cycled through a lot of them. Here's a list of games I've really enjoyed:
Since middle school
Tennis
I've played for as long as I remember. Let me know if you want to hit.
I've played competitively since middle school: four years on my high school's varsity team, four more on the University of Puget Sound team. Still hitting whenever I can.
