I'm Dan, a freelance Software Engineer. I previously worked at Google, Sidewalk Labs, Mt. Sinai's Hammerlab and Google again. I'm full stack, but tend to be drawn towards work that involves frontend and data. Data Visualization and Programming Languages are particular interests.

I wrote a book! Effective TypeScript (O'Reilly 2024). You can read more about it at effectivetypescript.com, on Amazon and Goodreads, but here are a few choice quotes:

Effective TypeScript explores the most common questions we see when working with TypeScript and provides practical, results-oriented advice. Regardless of your level of TypeScript experience, you can learn something from this book.

Ryan Cavanaugh, Engineering Lead for TypeScript at Microsoft

This book is packed with practical recipes and must be kept on the desk of every TypeScript eveloper. Even if you think you know TypeScript already, get this book and you won't regret it.
