Projects & apps

One app for the parts of life that usually live in a dozen tabs: spending, the job search, goals, notes, reading and newsletters. Its assistant, Dash, works across all of it, and Dash sessions plan, build and check most of the app's new features overnight.

A rolling 13-week cash forecast model built for a small service company. Built-in Monte Carlo simulation quantifies the probability of falling below a cash threshold, and the full model exports to formula-linked Excel.

An interactive IS-LM model for macroeconomics, with linked charts for the goods market, the money market and the labor market. Move the sliders for investment, savings, money supply and money demand and watch equilibrium shift against full employment.

A study tool that organizes the readings from a course syllabus and generates a summary of each one. Students sign in to keep their own syllabi and summaries in one place.

A web version of the For Sale auction board game. Run the auctions and try bidding strategies without the physical components.

An analysis tool for Matt Levine’s Money Stuff newsletter. It surfaces themes, tags topics and collects quotes so past pieces are easy to revisit.

Builds a network of linked ideas from a folder of notes, PDFs or exports. It works as a lightweight knowledge graph that helps you spot connections between your own material.
