NASA Earth Observatory

Flagship science-communication platform serving 1.5M+ monthly visitors with satellite imagery and Earth science data. Led the architectural overhaul of the publishing pipeline — re-platforming editorial workflows for distributed content teams and hardening the delivery layer for accessibility, performance, and search at scale. Set the technical direction that turned ad-hoc story production into a repeatable, self-service system built to evolve for the next decade.

Flood Mapping System

Mission-critical geospatial platform generating near-real-time flood inundation maps during active global disaster events. Architected the fully automated pipeline — from raw satellite sensor ingestion through geospatial product generation, dissemination, and integration with international emergency-management networks — engineered for fault tolerance and reliability when latency is measured in hours, not sprints.
