What I'm looking for

I’m looking for a remote-first team building low-latency, high-availability voice and clinical communications. I want to own reliability via automation, observability, and runbooks—partnering cross-functionally to ship durable systems with measurable SLO improvements.

I’m a Senior Voice and Clinical Communications Engineer with 10 years of experience designing and modernizing real-time communication platforms across SIP, unified communications, and resilient backend services. I focus on automation for deployment and recovery, model failure modes, and use data and metrics to guide prioritization, root-cause analysis, and service architecture decisions.

At Niantic, I shipped remote-first systems supporting large-scale, low-latency, n-tier applications. I improved reliability through observability and incident response—owning service health dashboards in Prometheus, Grafana, and Datadog—then turned incident trends and SLO breaches into backlog priorities for engineering teams.

I build durable platforms by partnering with engineering teams to translate customer needs into service architecture changes. I refined alert thresholds and runbooks to reduce paging noise, drove root-cause analysis on production regressions across APIs, databases, and network dependencies, and sequenced reliability fixes ahead of feature work when data showed elevated error rates or latency risk.

I bring the same operating discipline to clinical communications, contact center, paging, and high-availability services. From automated deployment and recovery workflows that reduced manual rollback steps from 12 to 3, to game-day simulations that validate resilience before releases, I help teams make recovery decisions documented and repeatable.
