I'm a software engineer who is passionate about open-source software, functional programming, and testing. I'm a perpetual learner who loves sharing my knowledge on all things code, career development and building products.

If I'm not tinkering on my own products, I'm working on open-source. I've published multiple successful packages, which are downloaded millions of times each month, and most notably helped maintainJest and theJest Community.

I also share my experiences over on myblog. You can expect to learn more aboutTypescript,Node,React,Testing, andFunctional Programming – with some content on career development and founding products thrown in too.

Twitter is the best place to keep up to date with what I'm working on, so follow along there for:

• 👨‍💻 Web dev, functional programming & testing in Typescript
• 🤩 Getting into / maintaining open source software
• 💸 Tech entrepreneurship
• 📢 Building in public
• 🧑‍🚀 Career advice

Or wanna chat? My DMs are always open 😊.
