About me

I'm a software engineer currently working as an independent contractor. I used to work at Triplebyte and before that at zyBooks. I've also taught a class on front end web development at General Assembly.

I mostly do full stack web work, but I also build iOS and Mac apps. I'm best with Rails, React, and Swift. You can reach me at me @ my domain if you'd like to hire me.

I'm really into Emacs (I'm the Daniel mentioned in the first sentence of this blog post) and my girlfriend's dog Winnie.

Things I've built and done

Window Flicker is a small window management utility for macOS that lets you "flick" your windows to different positions on your screen.

org-web is an online org-mode viewer and editor that's optimized for mobile use. It syncs with Dropbox and Google Drive. (And its open source!)

Find Hacker News Comments is a Chrome extension that lets you find Hacker News comments for the webpage you're looking at.

Icon Tryer Outer lets you easily test out icons on mobile devices.

Annotate is a little tool for annotating images with simple shapes. (its also open source!)

Tab Rearranger is a Chrome extension that lets you rearrange your tabs with keyboard shortcuts. Its super simple but I can no longer live without it.

YOLO is a Chrome extension I built with a friend that turns "Submit" buttons into "YOLO" buttons. Its proof that 11 lines of code can make a difference. I don't actually run this extension because its annoying. You probably shouldn't either.

I worked at Triplebyte from 2016 to 2018. Triplebyte helps engineers find jobs. They put engineers through a technical interview and only let the top folks through. They then introduce those engineers to partner companies who trust Triplebyte's vetting process.

I worked at zyBooks from 2012 to 2016. zyBooks creates interactive, online textbooks for college students. They've since been bought by Wiley.
