At Instacart, I shipped AI-powered product recommendations and demand forecasting for the retailer storefront, integrating model inference to surface personalized listings and inventory signals. I also developed Kafka-based event processing for inventory updates, order status changes, and customer notifications.
I reduced API response times from roughly 2.5 seconds to 800 milliseconds through PostgreSQL query optimization, Redis caching, and asynchronous Node.js handlers. I improved storefront page loads from 3.2 seconds to 1.1 seconds with React code splitting and lazy loading.
At Eversight, I built Python and FastAPI microservices for pricing experiments, promotions, and analytics, along with dashboards used by pricing analysts. I improved API response times and helped increase test coverage from roughly 60% to 85%.
Earlier, I developed software for digital banking at Capital One and backend services for exchange and clearing workflows at CME Group. That work included handling sensitive financial data, supporting an AWS migration, and building event-driven processing with audit trails.
