My research is referring multi-object tracking — getting a tracker to follow the objects a sentence is actually talking about. My side work is small tools I needed on a trip and shipped the same week. Both are below.
Open to 2027 new-grad SWE roles.
| Project | ||
|---|---|---|
| 01 | GMC-Link — camera ego-motion compensation for RMOT models, as a drop-in module. | +9.44 moving-class HOTA on Refer-KITTI, iKUN 27.70 → 37.14 |
| 02 | FlexHook-CF — counterfactual hard negatives for two-stage RMOT, extending FlexHook (CVPR'26). | Negatives built offline, so zero inference cost |
| 03 | case-smith — regression tests for legacy VB.NET from a 7–8B local model. | Structure is deterministic code; the model only fills semantics |
| 04 | stock-pred — multi-stock PPO agent over 46 Taiwan large/mid caps. | Redeployed live every day at 11:00 by CI |
| 05 | seanachan.github.io — this portfolio. Astro, static, no backend. | Complete 中/EN translation, not decoration |
| 06 | trip-schedule · trip-debt-calculator — itinerary from an Obsidian note; split the bill after. | Both live on Pages |
| 07 | Welcome-on-board — autonomous car on PIC18F4520, paired with a voice-command Android app. | 90% zero-shot voice-command accuracy |
