• Architected and implemented a mesh proxy that transformed inter-service communication, enabling asynchronous RPCs with sophisticated throttling controls and comprehensive observability across Life360’s backend services.• Led a redesign of the geolocation service architecture, resulting in a 10× reduction in request latency and a significant reduction in cloud infrastructure costs through a 33% decrease in compute fleet size.

• Optimized DoAT’s learning-to-rank models, achieving both faster inference and reduction in training time.• Architected and scaled critical backend services, including those for entity detection, trending news, user analytics, and graph traversal and querying.• Led an effort to promote WebP support in Mozilla’s mobile OS and browsers, with the goal reducing image payload sizes in DoAT’s apps by 20% without a noticeable loss in quality.

As a founding engineer at Cemmerce, I spearheaded the successful launch of their referral ad network by:• Leading the transition of backend development in-house, in close coordination with internal and external project managers.• Architecting and implementing a migration from a monolithic backend to a distributed stream-processing system using Apache Storm, which significantly improved costs by allowing the use of cheaper EC2 instances, while improving the time to onboard new properties from hours to under 2 minutes.• Establishing service reliability practices by collaborating with stakeholders to define Service Level Objectives (SLOs), then designing and implementing monitoring and alerting systems to ensure those SLOs are tracked.
