A living notebook for ideas in motion
A place for reproducible experiments, ideas still under revision, course notes, and small observations from campus and the city. Start with an essay, a working system, or an unfinished trail through the Notes.

Three ways into the archive
This is not a linear résumé. Essays, systems, and Notes connect to one another while keeping their own ways into a question.
0104 pieces
Writing
Long-form pieces that move between technical retrospectives, weather, and life around campus. Each stays in its original language.
0205 systems
Projects
Abstract questions made runnable and measurable, with the approach, boundaries, and outcomes kept in view.
03Living archive
Notes
A long-running archive of mathematics, systems, and AI—formulas, diagrams, code, and the derivations that were worth keeping.

Ideas that became systems
2026Reproducible experimental system · pipeline audited
FoodFlow: Recommendation & Fulfillment Simulation
Offline recommendation gains may create concentrated exposure, overloaded merchants, courier imbalance, and delivery delays downstream.
View approach and outcome
2026Active research · core reproduction complete
GeoSketch-CoT: Executable Geometry Scratchpads
Multimodal models may miss diagram relations or invent invalid constructions, while apparent gains can be confounded by extra reasoning tokens and output formatting.

2026Manuscript in preparation · core modules evaluated
IDAgent: Bidirectional Idea–Dataset Discovery
Ideas describe goals and hypotheses while datasets describe fields, modalities, and empirical boundaries; keyword search cannot reliably align the two.

Campus & City Observations
Not a photo portfolio—just weather, streets, and things noticed around campus.
Notes
Math, Systems & AI Notes
The long-running course notes now share the Astro design system while preserving admonitions, collapsible sections, Mermaid diagrams, KaTeX formulas, and code blocks in their original language.
