Achievements

Core Marketplace Architecture Rebuild

Led the design, implementation, and zero-downtime migration of the core marketplace architecture responsible for all order creation on StockX.
  • Built on event-driven design (Kafka), data-streaming frameworks (Flink), containerized microservices (K8s/Node/Typescript), and AWS infrastructure.
  • Migrated 10,000 req/s of API traffic without incident while maintaining a 15ms p99 latency SLA.
  • Achieved an 80% reduction in bid/ask time-to-market by optimizing caching strategy and Kafka consumer throughput.
  • Reduced an 8+ hour market recalculation process to 2 hours while eliminating all trading disruptions and client instability during execution.
  • Enabled the launch of the StockX Express Shipping Initiative, then successfully scaled to support the Verified Seller program. Combined, these two initiatives account for 50% of all StockX orders today.

Intelligent Fulfillment

Led the Intelligent Fulfillment initiative, decomposing the automated order reconciliation system to support more complex recovery rules, onboard new inventory sources, and improve operational visibility.
  • Stabilized order recovery to a consistent 60% rate for seller-cancelled, failed-to-ship, and failed verification seller items, recovering approximately $100K per week in net revenue. Replaced a previous process with a recovery rate that fluctuated heavily with market trends.

Dynamic Bid/Ask Matching

Designed and implemented a dynamic matching system enabling business teams to configure custom bid-to-ask matching ranges across a variety of product attributes. The underlying patterns and services became foundational to subsequent platform-wide initiatives.

    Fee Configuration System

    Delivered an upgraded fee configuration system that generated $6.5M in revenue in Q4 2021, with an estimated $37.5M impact for 2022.
