• Leveraged Core Java, Postgresql, Grpc, Redis, Kafka, & Zookeeper as the primary tech stack.
• Multi-Reward System:Engineered a multi-reward system for leaderboards and battles, enabling the simultaneous distribution of currency, items, and experience points upon completion.
• Micro services Decoupling: Led a major rearchitecture initiative to decouple a monolithic service into specialized microservices (Listing, Leaderboard), reducing P99 latency by 15% and significantly improving operational efficiency.
• Event-Driven Leaderboard Platform: Transitioned real-time leaderboard updates from a synchronous RPC to an asynchronous, Kafka-based event-driven model, which reduced network overhead, improved thread management by 25% and improved update latency time by 12%.
• Engineered a service optimization initiative that reduced getFeaturedEvents RPC latency, decreasing the average response time by 55% (from 155 ms to 69.9 ms) and P99 latency by 51% (from 262 ms to 127 ms) by implementing a Guava cache, multi-threaded data processing, and optimizing data retrieval logic.
• Multi-Cloud Data Migration: Executed a strategic migration of critical data and services from AWS to Google Cloud, including S3 to GCS and databases to AlloyDB, while also refactoring and deploying containerized services to Kubernetes.
• Engineered a new reward claim system for leaderboards, transitioning from auto-payout to a user-initiated claim variant and opt-in consent flow, which improved user engagement by 17% and increased unique user registrations by 10%.
• Game Configuration Service: Designed a dynamic service for real-time updates to in-app content and feature flags, built on a microservices architecture using GCP and a NoSQL database with built-in versioning and rollback capabilities.
• Collaborated with data science teams to engineer a dynamic lobby system that offers personalized entryFee options, effectively supporting user up-skilling and improving player engagement.
