Pocket-Sized Taste: On-Device Recommendation for Long-Tail Video Catalogs
Trained a 4.1 MB quantized two-tower model that ranks a 180k-title catalog entirely on-device, so no
watch history ever leaves the phone. Beat the cloud baseline on cold-start users by 8.4% NDCG@10 while
holding p95 inference at 34 ms on an iPhone 12.

Column-store database from scratch
Implemented a single-node column store in C with a B-tree secondary index, zone maps, shared scans and
a hash-join operator. Placed 4th of 71 on the course leaderboard for the final benchmark suite.

Reading Room β accessible study-space finder
A semester-long design study with six low-vision participants. Shipped as a campus web app that
surfaces quiet, well-lit study spots with live occupancy; ran two rounds of usability testing and a
full WCAG 2.2 AA audit.

What makes a seasonal anime survive?
Analysed 3,400 series from 2010β2024 to model which factors predict a second season. Studio track
record and week-4 retention mattered far more than premiere-week ratings β the finding that shaped
JKAnime's discovery feed.

Raft-backed sync engine
A replicated keyβvalue store with a Raft consensus layer and a CRDT merge path for offline clients.
The conflict-resolution design ended up almost verbatim in JKAnime's cross-device watch state.
