Designed and shipped a real-time user-signal pipeline (Android - ScyllaDB - Orion Feature Store) replacing asyncKafka sync with direct gRPC integration, cutting p99 latency to 6.2ms and enabling same-session feed personalization for millions of users. Owned end-to-end backend delivery for real-time feature-aggregation services powering PLP and PDPmodule personalization for 0-1 users, orchestrating parallel calls to multiple downstream service and a customGeo-Utils engine within a p99 ≤ 100ms budget. Architected a production embedding-based candidate generation system (31×32 user embeddings) integrated with a real-time feature store, which generates the user feed usingVSS on interacted product. Built orchestration DAGs for the FY ranking pipeline and led a cold-start personalization initiative using social-graph signals, enabling large-scale personalized feed generation across multiple experiments with projected 30% approxCTR/CVR uplift.

Collaborated with the FMS team to design pathfinding algorithms for warehouse robotics, implementingA* for shortest, traffic-free routing with dynamic traffic-light and turn-cost controls. Built live throughput/task-count visualization for real-time agent tracking using the ImGuiC++ library withinMovect software. Designed and optimized the Libao warehousemap, enabling smooth coordinated flow of 200 agents and achieving 10,000+ sortations/hour.
