About Me

👋 Hey there! I'm Divyansh, a full-time Senior Frontend Engineer at Rippling, part-time code whisperer, and full-time fan of dark mode.

Previously, I led Razorpay's global frontend efforts (hello Malaysia, Singapore and US 🌏) before recently joining Rippling. Come weekends and holidays, I switch gears, mentoring bright minds at ProPeers and AccioJob, and occasionally pretending I have a social life (spoiler: it's usually with code).

I was also recently invited by Airtribe as a Jury Member for an AI Tech Hackathon in Bangalore, because apparently, I now judge things other than bad variable names 😄

I'm passionate about clean code, clever UI, and helping devs level up their frontend game, all while debugging like a caffeine-fueled detective 🕵️‍♂️

Let's connect if you want to geek out over React, discuss internationalization (I might've open-sourced a thing 👀), or debate why undefined shows up only when you're on a roll.

Key Achievements

  • Built Industry's First Biometric Authentication: An OTP-Free Payment Checkout.
  • Created India's first token lifecycle management system for major banks.
  • Published a book "Full Spectrum JavaScript" with 200+ copies sold.
