About

I build resilient platforms that scale voice and visual experiences across mobile, Alexa, and cloud. As a Principal Engineer, I’ve led 0→1 platform teams and cross-org launches that helped Amazon Music reach tens of millions of listeners—and scaled Free Tier on Alexa to 1M+ voice customers in its first week. I own end-to-end client and service platforms, specializing in AppSync/GraphQL systems, AWS IoT, and low-latency mobile↔Alexa handoffs. My work includes architecting CloudQueue (surfaced 80–90% potential sync savings), building Media Kit used by Music Skills and Podcast integrations, and creating IoT push primitives that enabled sub-second handoffs and major casting cost reductions. I led the Alexa integration for Prime Music (and today supports Amazon Music Unlimited and Amazon Music Free Tier), achieving 57ms @P50 and 182ms @P90 latency, outperforming SLAs of 150ms and 350ms respectively. The voice gateway has scaled to 50K+ TPS at daily peak—demonstrating both architectural efficiency and operational resilience. I apply GenAI to automate developer workflows, preserve session context, and reduce mean time to reproduce complex bugs. I mentor engineers, PMs, and TPMs, establish operating models for repeatable delivery, and scale platform teams from 0→1. Open to senior engineering, platform, and technical program leadership roles focused on scalable client-cloud systems, voice/media integrations, reliability engineering, and cost optimization.

  • I lead platform integrations and cloud-to-device systems that scale Amazon Music’s voice and visual experiences across mobile and Alexa. I own the roadmap, architecture, and reliability of client-service platforms, driving cross-org launches and mentoring across disciplines.
  • Key achievements:
  • Architected CloudQueue, an AppSync-based system that centralized client/cloud queue state and surfaced 80–90% potential sync cost savings.
  • Designed IoT push primitives to replace polling, enabling sub-second mobile↔Alexa handoffs and reducing casting load.
  • Laid the technical foundation for Amazon Music Free Tier on Alexa, scaling to 1M+ voice customers in the first week.
  • Applied GenAI to automate developer workflows, preserve session context, and reduce mean time to reproduce complex bugs.
  • Guided Media Kit 2 design and implementation, enabling Amazon Music to fully compose Alexa CXs. Defined Alexa’s core primitives and exposed them—plus event sequencing APIs—so Alexa focused solely on primitive execution while Amazon Music controlled CX logic and state.
  • Advocated for migrating to the Alexa Music Skills Kit (MSK) as a shared interface between Alexa Entertainment and Amazon Music, replacing the need for a Media Kit 3. This accelerated development velocity, simplified third-party capability exposure, and aligned internal and external integration paths.
  • Led the Voice Experience Platform (VXP) migration, splitting voice experience generation out from the voice gateway to enable faster iteration and scaling. Built a common library for teams to generate experiences independently, including upsell and music queue generation. Introduced an intermediate routing service with heuristics to reduce load and improve targeting—replacing the initial broadcast-to-all model.
  • Founded and scaled 0→1 platform teams; created operating models, reporting lines, and mentoring frameworks for engineers, PMs, and TPMs.
  • Patents: Automated Queue Generation, Synergistic Queue Management

  • I focused on reusable integration platforms and voice-first discoverability for Amazon Music Unlimited, helping scale Alexa experiences across mobile and Echo surfaces.
  • Key achievements:
  • Built Media Kit, a reusable integration layer that standardized visuals, state sync, and control surfaces.
  • Enabled Amazon Music to take operational ownership of Alexa experiences for Prime Music and later AMU.
  • Took over Alexa integration for Prime Music, replacing the original Alexa-built implementation. Delivered latency of 57ms @P50 and 182ms @P90, outperforming SLA targets of 150ms @P50 and 350ms @P90—benchmarks set by the prior integration. Scaled the voice gateway to 50K+ TPS at daily peak, demonstrating architectural efficiency and resilience.
  • Supported Alexa device launches including the first Echo Dot, Echo Tap, Echo Show, and Alexa on Fire TV. Delivered platform integrations and voice-first experiences that scaled across mobile and Echo surfaces, with continued support for later generations.
  • Defined requirements and led cross-org collaboration for Alexa’s External Media Player interface on Fire TV, enabling voice requests to route to the Amazon Music app for richer in-app playback. Approved architecture to support continued voice control (e.g., next, previous, pause) post-handoff. Shaped new paradigms for syncing Alexa-generated queues with Amazon Music’s cloud playback systems.
  • Contributed to Alexa’s international expansion, supporting launches in the UK, Germany, France, Italy, Spain, and India. Delivered integrations and voice-first experiences that scaled across languages, devices, and regions.
  • Designed Media Kit to support “wow” utterances that improved voice discoverability and user engagement.
  • Designed and implemented track sequencing for search-based queues.
  • Delivered IoT casting primitives to sync playback state and metadata between mobile and Alexa, enabling low-latency handoffs and reducing casting load
