Cartoon drawing of my face

Overview

I build production software at scale , from a React PWA serving millions of concurrent students during the Digital SAT to a TypeScript monorepo shipping to 5 platforms from a single codebase.

I've been building software professionally for 9 years, each project increasing in complexity and sophistication. I've been writing code for 16 years.

In the last year I've written over 500k lines of code implementing dozens of features and hundreds of bug-fixes across enterprise production systems with strict correctness and availability requirements.
