A from-scratch Transformer for English–Chinese translation, with a live attention heatmap.
An LLM pipeline that turns a tender document into a requirement matrix and proposal outline.
Space reserved for whatever I build next. Nothing here yet — check back soon!
Guestbook coming soon! For now, just imagine a very enthusiastic "Great site!! 5 stars!!" from a stranger in 1998.
