I’m a software engineer and entrepreneur focused on modern web technologies and AI.

Here's an ongoing autobiography, which also shares the story of my by-the-bootstraps "unschooling" education: now the subject of a chapter on grit and resilience in the bestselling book Mindshift by Barbara Oakley.

An angel investor once described my core soft skill in the role of founder or early team member as: "The ability to perceive exactly what needs to be done. And then to do it."

My experience working in difficult environments around the world means that I can be trusted to get things done, even when things go wrong.

In the past, I coined the term "Startup Cities" as co-founder of StartupCities.org and a startup spinoff, both of which focused on why startups should build cities. I now write about Startup Cities at StartupCities.com

I've won several awards for economic research and have been published or interviewed in Virgin Entrepreneur, a16z's Future.com, The Atlantic's CityLab, Foreign Policy, and in academic volumes by Routledge and Palgrave MacMillan.

Wait... what is this site?
This is my personal portfolio, inspired by the question: "What would the opposite of the two-color template developer blog look like?"

SpecAugment (In Pytorch)

State of the Art Data Augmentation for Speech Recognition

Collaboration with qcai2002 at FastAI 2019

A Pytorch implementation of Google Brain's SpecAugment: A Simple Data Augmentation Method for Automatic Speech Recognition.

As far as I know, this was the first and so far only implementation of this paper in Pytorch. It required porting Tensorflow functionality to Pytorch, including writing many difficult functions from scratch since Pytorch did not support many necessary operations.
