About

Hi, I'm Darshan

I'm a Senior React Native & Frontend Developer with 4+ years of experience designing, building, and shipping enterprise-grade CRM, SFA, and ERP mobile applications for Android and iOS — and I'm currently open to new opportunities.

I specialize in React Native apps with native Kotlin (Android) and Swift (iOS) modules — background location tracking, biometric authentication, real-time features with Socket.IO and Firebase Cloud Messaging — architected within Nx Monorepo codebases for enterprise field-sales and manufacturing teams. I've since expanded into React and Next.js frontend development, bringing the same production-first mindset to the web.

I own releases end-to-end across Play Store and App Store Connect, resolve production issues independently, and review code to help junior developers ramp up faster. I lean on AI-assisted tooling (Cursor, Claude) to move quickly without cutting corners on quality.
