Amazon - Software Development Engineer
- Present
- Architected a unified notification platform from scratch on AWS Step Functions, consolidating two legacy services after evaluating three candidate architectures — cut new notification-type onboarding from ~1 month to ~1 week (a partner team shipped a new type end-to-end in 7 days).
- Root-caused 4 months of recurring Sev-2 incidents (23+ total) in distributed DynamoDB-stream processing — where propagation lag spiked from minutes to 29+ hours across 4 regions — and led the migration to an event-driven serverless (Lambda) architecture; zero incidents since.
- Diagnosed an org-wide cache race condition generating 9,000+ errors/hour on a service handling millions of requests — an issue multiple teams had only worked around; root-caused and deployed a worldwide fix in a single day, raising service availability from 97.45% to 99.999% and sustaining it through the rest of the year.
- Cut a cross-region compliance-migration outage window from ~6 hours to under 15 minutes (24x) by designing a pre-staged deployment across 3 teams in 3 time zones — zero lost events and zero manual intervention; adopted as the template for later migrations.
- Traced a 50% drop in a leadership-reported conversion metric through the full analytics pipeline to 36 bot accounts producing 87% of traffic with zero submissions — proved no customer regression and delivered both a self-service query and a permanent pipeline fix.
- Apply AI coding agents fluently across day-to-day engineering — writing and reviewing code, drafting docs, and accelerating on-call investigation — and author service-specific agent skills and context so the agent stays grounded and accurate.
- Built an AI onboarding skill for one of my team's services so away teams could self-onboard and resolve questions about how the service works without support; and orchestrated a multi-team campaign where scheduled AI jobs tracked responses across tickets — updating docs, recording deadlines, marking completion, and flagging only the tickets needing my attention.
