• 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.

• Led migration of a legacy Backbone.js/.NET admin dashboard to React/TypeScript, introducing component tests and CI pipelines. This overhaul improved maintainability and accelerated feature delivery by 3×, enabling more frequent releases. • Developed new features in Next.js (SSR) with Tailwind CSS and React Query for data caching. Integrated Node/Express APIs to support these features for field operations users, reducing their manual workload. • Built a responsive, mobile-first layout using Tailwind CSS, ensuring cross-device usability. Optimized API error handling for operations dashboards, improving system reliability during peak loads.

• Consolidated multiple frontend codebases into a Turborepo monorepo. This cut CI/CD deployment time by 30%, improved dependency sharing, and reduced maintenance overhead across services. • Built a centralized Node.js PDF microservice with versioned templates, replacing 5+ client-side invoice generators. Reduced code duplication by 60% and enabled teams to update invoice designs without new deployments.

• Engineered a Google Maps-based delivery-area configurator (React). Enabled ops teams to draw polygonal delivery zones across 20+ cities and assign SLA tiers, which supported a new 1-hour express delivery option. • Built an offline-first PWA for warehouse inventory management (React/Node.js). Implemented service-worker caching to prevent data loss, reducing manual entry errors by 45%. • Implemented a real-time notification system (WebPush + Redis pub/sub + SSE) to push order updates to warehouse staff. This cut the SLA breach rate from 70% to 15%, ensuring timely dispatch updates. • Optimized build performance (Webpack 5, parallel minification) to shrink production build time by 80% (15→3 minutes). Improved bundle sizes by 60% (code splitting and tree shaking), raising Lighthouse performance scores above 90 on key pages.

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.
