Over the last 5 years, I've been working on single page applications using node.js, React, Knockout & Vue. I'm fond of smart, useful, responsive UI. TDD, DDD, OOP, FP, MVC, SOLID, DRY, CI/CD, mobile-first, PWA.
Experienced in debugging. Like to delve into an unfamiliar library and figure out how it works, what algorithms are used, find some undocumented API.
Also, I'm a big fan of web-page performance. Fewer queries, smaller bundles, lazy loading, FOUT, FOIT, FOFT, Offline & Service Workers, and other such niceties.
