Interactive projects
A small shelf for the interactive tools I build. Some are public and live on this site; some stay private for internal work but still deserve a short project note. I keep the public link here when it is open, and use screenshots when an app is meant for internal use only.
A course and knowledge hub for economists and researchers learning to control AI agents through task contracts, context engineering, skills, memory, tools, and verification loops.
A static dashboard for tracking reposted ideas, tools, papers, and research leads. It maps reposts by topic and recency, supports search and filters, and keeps review status, priority, bookmarks, and private notes locally in the browser.
A searchable expert tracker arranged as a quiet galaxy view. It helps scan researchers by field, department, and selected work without turning the list into a long static directory.
A small reading shelf for books and papers from the past year. It keeps the reading surface separate from the homepage while still making the collection easy to open from the app hub.
A private Vietnamese Zi Wei Dou Shu web app for casting a natal chart, reading palace-level interpretations, and searching a curated knowledge base built from classical Tử Vi sources.
The visual identity uses the celestial wheel from the app hero: dark ink background, brass orbit lines, constellation marks, and a small red seal motif.
An interactive map for checking generation assets and grid infrastructure in one place. Open the atlas to filter plants, inspect locations, and move between the plant layer, transmission backbone, substations, and data centers.
A DEPOCEN internal app built to simulate tobacco-tax scenarios across the base year and the following five years. It helps researchers and policymakers compare how specific tax paths can affect cigarette consumption, retail price, tax revenue, smoking prevalence, and smoking-related deaths.
An internal mapping app for exploring tobacco retailers in Hanoi and Ho Chi Minh City. It combines store locations, product and brand availability, prices, and retail characteristics so users can search shops and inspect the local retail environment in detail.
