    Nueva York, United States
    •Reduced API response times from ~10s to ~1s on critical endpoints by rewriting inefficient LINQ queries — split queries and programmatic materialization to avoid costly in-database joins at real-world data volumes.
    •Resolved a systemic data consistency problem in the rewards pipeline: the missing distinction between unlocked, redeemed, and used states was causing order/payment incoherences in production. Redesigned the state model with the product team.
    •Refactored the order processing flow (placed → payment received → rewards applied), eliminating race conditions with Stripe and standardizing the service contract.
    •Built the foundational unit testing layer for the project, establishing patterns adopted by the team as standard.
