Back Home Side Projects by Quentin Donnellan


Lessonwell started out as a personal project for my own Calculus class. I wanted a content management platform based on Markdown and MathJax that I could use to quickly prototype lessons without navigating through insanely complicated education CMS (which is basically every education CMS).

This website (

I've used this website as a sandbox for learning new stuff over the years. What started out as a Google Sites website has see everything from PHP, Python (both webapp2 and Flask), and is currently a Go application. Everything you see is here is open source, and usually in transition!

One of my favorite features of lessonwell (above) is a real-time Markdown/MathJax editor that I created to make prototyping math lessons super easy. I used it as an excuse to learn Go and KnockdownJS on Google App Engine and created this tiny standalone app.

Hone School was less of a software project and more of an after school program for kids in my area. We taught them Ruby using the Sphero robot. I had to drop this project when my own child was born, unfortunately. I built up a rather nice-looking curriculum platform and marketing front-end.

The Badge Project

This has probably been my most ambitious (and likewise buggy) application yet - an attempt to create a badge-based gradebook. I actually used this for a marking period in my Calculus class with great success. I underestimated the amount of time it took to teach and maintain this project so I had to kill it. Would love to revive one day...

When I built speculess I was going through a holy cow mirrorless cameras are the best thing since sliced bread phase. It was good motivation to whip up a python webapp with a totally different focus from anything I'd done before.

Long before there was Lessonwell there was qCalculus - my attempt to synthesize everything I liked about Udacity and Khan Academy into an app made exclusively for my calculus students. This was also one of the very first Python app I ever built.
