Designed and shipped a real-time user-signal pipeline (Android - ScyllaDB - Orion Feature Store) replacing async Kafka 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 PDP module personalization for 0-1 users, orchestrating parallel calls to multiple downstream service and a custom Geo-Utils engine within a p99 ≤ 100ms budget Architected a production embedding-based candidate generation system with 31×32 user embeddings and VSS on interacted products, integrated with a real-time feature store, and built FY ranking DAGs with social-graph-based cold-start personalization, driving large-scale feed generation with a projected 30% approx CTR/CVR uplift

• Owned testing and review readiness for three backend services in Meesho's AI Blitz - bootstrapped service-test-kit coverage and generated repo-specific review guidelines to gate AI-assisted development
• Contributed to personalization experiments achieved +2.5% 1ODNR improvement in first-session feed relevance
• Awarded Star Performer of the Quarter by GM-Growth (Meesho) for demonstrating the "Lightspeed" competency
• Served as co-owner of Meesho's in-house URL shortening service (mini-url)

Software Development Intern at ADDVERB TECH. LTD. (2024-05 – 2024-07)

• Collaborated with the FMS team to design pathfinding algorithms for warehouse robotics, implementing A* 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 ImGui C++ library within Movect software
• Designed and optimized the Libao warehouse map, enabling smooth coordinated flow of 200 agents and achieving 10,000+ sortations/hour
