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.
