About

I help fintech and e-commerce platforms deliver lightning-fast, scalable web experiences. Over 4.5+ years, I’ve built React/Next.js applications in high-growth teams (Tata 1mg, Cashfree) that process millions of transactions. For example, at Cashfree, I designed a micro‑frontend fraud rule engine enabling 200+ merchants to self-configure rules, eliminating the need for code redeploys. I thrive on optimizing frontend performance (improving load times by ~80%) and integrating AI-driven features. Let’s connect if you’re focused on building next-generation web products.

Frontend Engineer 2

Mar 2025 – May 2026 · 1 yr 2 mos · Bengaluru, Karnataka, India · On-site

Lead front-end development of Cashfree’s Risk WebApp (React/TypeScript), serving 200+ enterprise merchants and handling millions of daily transactions. Improved the fraud dashboard’s efficiency by implementing a micro‑frontend architecture with Zustand state management, which enabled self‑service rule configuration without code redeploys.
Architected a schema-driven, micro‑frontend fraud rule engine in React/TypeScript (with Zustand), allowing merchants to configure transaction-blocking rules at runtime. This eliminated zero-downtime deployments for rule changes and empowered 200+ customers to adapt quickly.
Reduced Video KYC session drop-offs by 30% by implementing a resilient reconnection state machine (React/Redux, exponential backoff). This significantly improved verification success rates for low-bandwidth mobile users.
Developed Cashmere, Cashfree’s React component design system (Storybook, Figma integration). Built backward-compatible primitives and automated scaffolding (CLI), enabling multiple product teams to reuse components and speeding up UI development.
