Led backend BFF services for the Hollywood Add-On purchase journey on JioHotstar (Web & Android), owned API design, downstream integration, and production rollout for systems serving 1M+ DAUs, driving 39% paywall conversion uplift and 80% add-on adoption. Built subscription ingress and paywall flows for Samsung & LG TV platforms, scaled to 200K+ daily impressions across systems serving 4M+ DAUs, improving paywall reach by 22%. Developed a server-driven dynamic paywall nudge for concurrent stream limit users, targeting 6.8M monthly concurrency errors across 10M+ DAU systems, with projected 19% paywall-to-subscription conversion among impacted free users. Built a frequency-capped event delivery system for migration popups across 40M+ users, implemented exactly-once delivery semantics using caching and client-side persistence within distributed systems serving 10M+ DAUs. Designed idempotent subscription transfer APIs with HID migration workflows in Java, enabled ~80% self-serve adoption, saving $4K/month in operational costs. Migrated read queries to dedicated RDS read replicas across systems handling 100K+ RPM, reduced write cluster read load by ~34%, rolled out behind config flag with replica lag monitoring. Implemented Kafka routing logic for the Microdrama Communication Service, maintained backward compatibility across distributed event paths serving 200K+ DAUs. Owned backend business logic across BFF and gateway layers integrating downstream microservices for platforms handling 500K+ RPM workloads.
