Optimized Add Cash flow for IPL peak traffic (3x load) by implementing asset chunking, async preloading, and native caching, reducing load time from 2.9s to 771ms (70% faster) and significantly boosting user transactions.

Engineered and deployed Server-Side Rendering (SSR) and advanced front-end optimizations for high-traffic advertisement banners, reducing load times and improving user engagement.

Designed and launched an Over-The-Air (OTA) update system with BSDiff patches and checksum validation, reducing bundle size by 90% and enabling phased rollouts to 10M+ users on AWS (DynamoDB, Redis, S3).

Re-architected real-time timer mechanisms using centralized signals and selective subscriptions, drastically cutting CPU usage by 99%+ (from 3,300 to 32 re-renders/second) for smoother UI performance.

Refactored the match lobby using an entity-based data pattern, optimizing store structure and state management, and leveraging Redux Thunks to streamline data flow and boost application performance.

Developed "FastLottie," a custom React Native framework incorporating persistent caching and offline support, which enhanced animation load times and user experience on low-network devices.

Enhanced UI/UX by optimizing Tailwind CSS components, significantly improving rendering efficiency, cross-device responsiveness, and achieving pixel-perfect design precision.

Developed a unified data layer leveraging GraphQL APIs, establishing logical entity representations, and simplifying data access for internal and external services across multiple tables.

Implemented robust event-driven pipelines using RabbitMQ and Redis for real-time marketing campaigns, directly contributing to a 35% increase in customer engagement.

Engineered resilient workflows for real-time rewards distribution, incorporating advanced monitoring, automated retries, and idempotency to ensure fault tolerance and scalability.
