Hi, my name is

Swapnil Bhojwani.

I build things for mobile & the web.

I’m a software developer specializing in building high-performance mobile and web applications. Currently, I’m building performant cross-platform experiences at Stanverse Technologies.

About Me

Hello! My name is Swapnil and I enjoy building things that live on phones and the web. I love working at the intersection of great UX and solid engineering — whether that’s optimizing a Next.js storefront or building a real-time ML inference library in React Native.

Fast-forward to today, and I’ve spent 3+ years shipping production apps. At Stanverse Technologies I architect config-driven UI systems for stanshop.co, an e-commerce platform handling 30Cr+ GMV monthly. Before that, at Bombay Softwares, I built everything from on-device computer vision to offline-first enterprise apps.

I also maintain expo-splitkit, an open-source A/B testing library for Expo, and write on Medium about what I learn.

Here are a few technologies I’ve been working with recently:

  • React Native
  • Next.js
  • TypeScript
  • JavaScript (ES6+)
  • Kotlin
  • Kotlin Multiplatform
  • Node.js
  • Firebase

Where I’ve Worked

Software Developer @ Stanverse Technologies

Aug 2025 - Present

  • Architected a BFF layer for stanshop.co (30Cr+ GMV monthly) with config-driven UI enabling dynamic feature rollouts without redeployment
  • Boosted Next.js performance score from 10 → 50–60 via code splitting, lazy loading, and SSR
  • Improved LCP across platforms — reduced "poor" LCP from ~80% → ~35% on Android and ~75% → ~35% on mobile web, lifting "good" LCP to ~25–30%
  • Doubled buy conversion rate from 30% → 60% through optimized navigation UX flows
  • Designed monorepo architecture (Stanshop + Photon) improving developer productivity and CI/CD efficiency
  • Integrated Fliq blockchain trading platform via WebView, supporting ~500K transactions
  • Handled Partner Tag whitelabeling of Stanshop, enabling white-labelled storefronts for multiple partners from a single codebase
