Senior🎓
Top SchoolDave Purrington is a distinguished engineer with over two decades of hands-on and leadership experience building scalable platforms, most recently shaping AI and knowledge systems at Atlassian and now leading AI/API gateway work at Capital One. He designs event-driven, highly available architectures and pioneered a legally approved, fully automated LLM-driven system to continuously improve support content for millions of users. Dave has repeatedly scaled organizations—from small teams to 40+ engineers—while driving migrations to cloud-native microservices, observability standards, and developer productivity tooling. His work blends deep engineering (Node.js, TypeScript, AWS serverless, Kubernetes) with product impact, such as a migration that improved Lighthouse scores and targeted significant cost avoidance. He thrives on hard, high-stakes problems and has a knack for introducing agentic programming and evaluation frameworks that make AI systems auditable and production-ready. Based in Stonington, CT, he pairs strategic architecture vision with day-to-day coding fluency and a proven track record of delivering measurable operational improvements.
