About Me

I'm Divyansh, a Software Engineer II (L6) at Rippling on the Web Infrastructure team, where I work on CI/CD pipelines, developer tooling, E2E test observability, and deployment infrastructure using AWS, Datadog, Buildkite, and Playwright.

Previously, I spent 4+ years at Razorpay as a Senior Frontend Engineer, leading the international expansion into Malaysia and Singapore (530 merchants, 80M MYR GMV), building Mastercard Biometric Authentication (demoed at GFF 2024), and open-sourcing the i18nify-js SDK (100K+ weekly downloads, 27+ teams).

Outside work, I freelance as a React instructor at AccioJob and have mentored 100+ students at Airtribe. I was invited as a Jury Member for an AI Tech Hackathon in Bangalore. I've also authored 3 technical ebooks with 200+ copies sold.

I'm passionate about clean architecture, developer experience, and building tools that make engineering teams more productive.

Rollup Is Not Just for Libraries Anymore

For years we quietly assumed Rollup was the library bundler and Webpack was the application bundler. That line has blurred considerably. Here is why Rollup deserves a second look for your next production application.

React 19 Actions Are Not a State Management Solution

The new Actions API is a solid improvement for handling async mutations and form submissions. But teams are already reaching for it as a Zustand or Redux replacement, and that's a category error that will bite them at scale.
