Experience

• Delivered instant reward redemption as a key product milestone by fully automating payouts through Cash free, replacing manual and offline payment workflows increasing operational excellence. This enabled companies to offer real-time rewards at scale & directly drove increased client adoption and inbound sales interest.
• Implemented an event-driven architecture using Kafka to replace async API calls, reducing request latency by ~40% and improving service decoupling across microservices. Offloaded background job processing to a centralized, queue-driven service with a configurable control switch, enabling load leveling between producers and consumers, boosting throughput, and significantly reducing synchronous request response times.
• Refactored the platform from a single-tenant model to a multi-tenant architecture using feature-based configuration to enable dynamic, client-specific behavior. This redesign significantly accelerated client onboarding and improved white-label mobile app delivery speed by ~80%.
• Implemented multiple authentication & messaging providers to optimize billing costs and improve delivery reliability across regions. Added country-specific provider routing with intelligent fallback to a global vendor based on delivery attempts, also implemented rate limiting to prevent abuse, ensuring high availability and consistent user authentication experience.
• Implemented a multilingual translation framework across the application to support multi-geographic adoption. Designed dynamic configuration for persisting and serving localized content across multiple languages. Introduced a caching layer to optimize read-heavy access patterns, significantly reducing database load and improving response latency.

• Led and mentored a team of 3 junior engineers to architect and deliver a full-scale modernization of a legacy .NET monolith into a decoupled web platform. Rebuilt the system end-to-end using React and Node.js, enforcing SOLID design principles and OOPS patterns, and delivered core platform capabilities including authentication, media services, deployment workflows, device health reporting, and large-scale legacy data migration.

• Streamlined customer data onboarding by implementing end-to-end digital workflows for digitization & centralized dashboard.
• Optimized server performance & reduced network bandwidth usage by migrating media uploads to S3 using pre-signed upload URLs.
• Built a scalable reporting service using batch processing to generate metrics, insights, and evolving requirements for active users.
• Integrated Vonage APIs to enable in-app video calling during the COVID-19 period, increasing engagement across active user base.
