I’m a frontend engineer with 4+ years of experience building and optimizing production React and React Native products. My work combines product ownership with performance engineering. I have reduced JavaScript bundle size by 35%, reduced application size by 42%, and improved the crash-free rate to 99.3%. I have also shipped real-time mobile products serving 150K+ daily active users and payment infrastructure processing 900K transactions per month. At HiRobin, I built core parts of an AI phone assistant, including the React Native application architecture, Android native dialer modules, call-forwarding workflows, payments, real-time chat, WebSocket integrations, and backend foundations for VoIP. I’m currently building an offline-first field-operations console using React, TypeScript, Leaflet, Zustand, TanStack Query, IndexedDB, Recharts, REST and WebSockets. The project focuses on geospatial interfaces, unreliable networks and constrained-device performance. Core technologies: React, React Native, TypeScript, JavaScript, Zustand, TanStack Query, Next.js, WebSockets, Android native modules, performance optimization, NestJS, Go, PostgreSQL, Kafka and ClickHouse. Open to Frontend Engineer, React Engineer, React Native Engineer and SDE-2 opportunities in Bengaluru and across India.
