About

I am Edward Li, a software engineer.

I have worked independently since 2021. The two projects on this site are my work now. Before that I did data analysis for a credit card issuer's marketing and retention teams, product and fundraising at a health-records startup, and economics research at Johns Hopkins.

Now

Process is a development method in which model sessions do the work and a person decides only what a person must decide. It is used to build the Product, and to build its own tooling. Product is a local-first tracker on a bounded engine.
