Essential software development patterns, principles and tutorials with modern JavaScript and TypeScript.

By a software developer / designer, musician based out of the GTA currently working as a JavaScript consultant.


I co-founded Univjobs in 2017 and learned a lot about making code scale. At some point during my current work at Aquent Dev6 as a consultant and reading as many books on software as I could digest, I've come to realize that there were a lot of pitfalls I could have avoided if I knew the patterns and principles to guide me. That's what this site is about: things I think all professional software people should know.
