Top SchoolCameron Llewellyn is a Senior Software Engineer with a decade of experience building high-traffic GraphQL APIs and multi-tenant SaaS architectures, most recently helping scale a platform to 115k weekly active users and 12,000 peak GraphQL requests per minute. He combines backend expertise in Postgres (managing databases with 110M+ records) with data engineering using Python and Astronomer to deliver reliable ingestion pipelines and integrations. Cameron has led migrations, upgraded production databases with minimal downtime, and established API standards and testing practices that improved team quality and performance. He also runs a small business where he architected a robust 3-2-1 backup workflow and handles SEO and analytics, reflecting a practical, operational bent beyond pure development. Based in Yukon, Oklahoma, he enjoys tackling complex problems end-to-end—from mobile apps and GraphQL schemas to infrastructure and observability—and is known for a hands-on, curious approach to tinkering with new technologies.
