About

Engineering manager/player-coach in the Alexa media ecosystem who led delivery of a Tier-1 gateway service enabling third-party providers (e.g., Spotify/Pandora) to control playback across users’ Echo devices, driving 10–15% lifts in engagement metrics. Deep in API design, AWS infrastructure choices (EC2 vs Fargate), OAuth/LWA auth flows, and production rigor (security reviews, load testing, feature-gated dial-ups), with demonstrated incident ownership and operational automation wins.

Key Strengths

• Led launch of Tier-1 gateway service exposing 8 APIs enabling 3P apps (e.g., Spotify/Pandora) to control media across Alexa devices
• Drove cross-team API design alignment and resolved nomenclature/contract conflicts via structured 1-pager and stakeholder syncs
• Strong execution on end-to-end delivery: infra selection (CoralRest, EC2), auth integration (LWA/OAuth), security review, testing, and production rollout behind API gateway
• Quality-focused engineering leadership: feature-branch workflow, pre-prod end-to-end testing evidence in CRs, and enforcing unit/integration test coverage
• Performance optimization mindset (introduced caching/memcache to reduce downstream calls and save ~10ms per request)
• Incident/reliability ownership: diagnosed and fixed Amazon Music playback initiation issue by implementing External Media Player workflow; validated via gamma testing, QA, feature gate, and 3-day dial-up
• Scoped ambiguous product work with tradeoffs (reduced scope from all providers to 2P due to legal ambiguity) and managed dependencies to ship
• Operational efficiency improvement: automated ~300 manual Q4 throttling config updates, reducing effort from ~3 days to ~2 hours
