Who?
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?"

node-record-lpcm16-ts

I've been working on an audio-related app for one of my clients recently.

I ended up writing a TypeScript port of the popular node-record-lpcm16 package, which hadn't been updated in years and lacked TypeScript support. I've modernized the codebase and added full TypeScript bindings. This also prevents certain weird errors and warnings from appearing when the library is used in more modern projects.

import { record } from 'node-record-lpcm16-ts';
import fs from 'fs';

const file = fs.createWriteStream('test.wav', { encoding: 'binary' });

const recording = record({
  sampleRate: 44100,
  channels: 1
});

recording.stream().pipe(file);

// Stop recording after 3 seconds
setTimeout(() => {
  recording.stop();
}, 3000);
