Ajay Poshak

Staff Software Engineer at HackerRank. Previously BookMyShow.

I care about web performance, build systems, and understanding how things work under the hood.

Things I've shipped

  • Cut CI build times by 54% at HackerRank through incremental caching
  • Reduced page load times by 14% across the entire HackerRank app by eliminating unused CSS
  • Added dark mode to the Node.js documentation — merged into Node.js core (v15.6.0)
  • Reduced bundle size by 17% at BookMyShow using differential builds for modern browsers
  • Led internationalisation to add 2 new languages, driving customer retention and acquisition
  • Built coachmarkJS — an npm package for creating onboarding experiences with zero config

Things I've built from scratch to learn how they work

Project What it is Language
toy-redis In-memory key-value store over TCP Go
build-your-own-auth JWT and auth strategies without libraries JavaScript
server-components React Server Components from first principles JavaScript
url-shortener URL shortener service Go
