Rockstar🎓
Top SchoolTim Welch is a senior software and data engineer in Portland, Oregon with 19 years of experience building cloud-native, geospatially-focused systems and analytics. He combines hands-on engineering—designing serverless geoprocessing frameworks, ETL pipelines, and interactive map-based UIs—with team leadership and mentorship across startups, non-profits, and research institutions. Tim has repeatedly scaled geospatial analysis for performance (including a 10x Lambda-based improvement) and delivered cloud-optimized data products and CI/CD workflows for complex marine and urban planning use cases. Equally comfortable with TypeScript/NodeJS, React/Mapbox, PostGIS, and AWS infrastructure, he translates domain complexity into practical, production-ready services. Outside engineering he has a background in pottery and applied design, reflecting a pragmatic creativity that informs his product and UX sensibilities.
