At Amazon, I support and maintain backend services for the Selling Partner API, which lets third-party sellers and vendors manage product listings across marketplaces. I completed a multi-region rollout of centralized rate limiting for seller catalog writes, validating capacity for 15,000+ TPS.
I also implemented checkpoint-based recovery for bulk JSON listing feeds, enabling incremental processing of 25,000+ SKU feeds and product-level error reporting. For regional cutovers, I migrated seller submission records and extended listing metrics pipelines while preserving operational monitoring.
Earlier at Amazon, I built an onboarding platform for engineering organizations and developed event-driven workflow integrations. I also built a notification platform reaching 500,000+ Amazon sellers; outside work, I’m building an EV charger availability monitoring platform with backend aggregation and user alerts.
