At SellerGeni, I architected the Rule Builder, an Amazon Ads condition-to-action automation engine built with Node.js, Express, and MongoDB. It supports nested conditions, more than 20 action types, and campaign guardrails.
I also owned batch and scheduled job processing across 140+ jobs and 22 queues, handling millions of Amazon Ads and SP-API records nightly. I developed DayParting, which automated campaign scheduling across all 24 hours and saved $1M per month in ad costs.
Outside my work at SellerGeni, I built a Node.js reverse proxy with multiple load-balancing strategies and a circuit breaker, and implemented IP, ICMP, and TCP from scratch in Python for PyTCP.
