I’m very keen to discuss new software engineering and/or technical writing positions, particularly those in the embedded or macOS development arenas. Contact me via any of the platforms linked at the top right of this page.

Until recently, I was a Senior Software Engineer with IoT communications company Kore Wireless for its Device Builder division. Previously, I spent three years as a Developer Educator at Twilio and six as Senior Tech Writer at IoT platform-as-a-service company Electric Imp, which Twilio acquired in 2020.

Before all that, I was a technology journalist, 15 out of 25 years spent in senior roles on the website The Register. I have also contributed to a wide array of publications and news organisations, including The Times, The Guardian, The Independent, the BBC and CNN. You can view samples of my work for these and other publications in my portfolio.

This site is dedicated to my own open source commercial and non-commercial programming projects. If you’re looking for my blog posts, you’ll find them at Smittytone Messes with Micros. Curious about the logo fonts? Then read about them here.
