Enhancing Amazon customers’ ordering & checkout experience.
•Ensuring availability of Amazon’s core checkout services by developing tools to stress test for high velocity events like Black Friday, Prime Day, Diwali.
•Optimizing customer experience by developing algorithms to prioritize important requests & throttle lesser important requests like bots.
•Buildig inbound & outbound traffic-priority algorithms in the core Ordering service shielding 60+ critical downstream services to detect hot-SKU (ex: PS5) spikes and throttle bot traffic to protect inventory, prevent promotions fraud, and prioritize real customers; preventing recurrence of $3.8MM losses in revenue and 170K+ dropped orders in prior peak shopping event - Prime day ‘23.
•Scaled a low-TPS regression tool to a distributed stress testing execution tool enabling up to 220k TPS for peak event readiness; uses recorded prod-traffic replay with selective API stubbing of stateful
dependencies to prevent unintended production writes.
