Conceived and led development of a new cloud platform throughout the entire lifecycle, including cloud provider selection, platform architecture, tool and service evaluation, API design, and cost-effectiveness analysis.Designed, architected, and implemented a data ingestion platform that collected and analyzed over 560 million utility meter readings per month while reducing operating costs by more than 30% over the previous implementation.Collaborated with hardware and firmware engineers to design and build a data ingestion API for collector hardware that reduced in-flight data volume by 90%, resulting in a 75% drop in collector operating costs, decreased complexity in device firmware, and improved collector performance.Created a multi-tiered data warehouse solution, including ongoing data aggregation and analytics processes that simplified access to meter data across the platform, reduced data storage and access costs by over 70%, and improved query response times by 40%.Built data-relaying services that allowed for seamless phased cutovers from legacy to new architecture for IoT devices, web users, and mobile app users.Worked with operations and business teams to build observability and alerting tools to support large-scale hardware deployments, customer onboarding, support, and site analysis needs.

Collaborated with data scientists to develop, train, and maintain a machine learning (ML) microservice to predict an individual household’s resource usage (electric, gas, or water) over multiple weeks based on past and predicted weather conditions and past energy usage (both by that household specifically and by the surrounding region as a whole).Performed load testing and capacity planning to determine capability and cost of existing infrastructure to support projected demands; used testing results to identify the need for a modernized cloud platform to support the company roadmap beyond 2 years.Managed, maintained, and enhanced multiple internal- and external-facing management UIs.Added functionality to and improved performance of customer-facing APIs for managing and accessing utility meter data.
