Rockstar🎓
Top SchoolDoug Nelson is a Senior Systems Engineer with 11 years of experience building and operating large-scale, resilient cloud platforms across roles at Cloudflare, Shopify and Silktide. He combines deep systems and backend expertise with practical DevOps craftsmanship—Terraform, Packer, zero-downtime deployments, and Docker-based developer parity—to keep mission-critical SaaS infrastructure performant and reliable. Notable achievements include designing an atomic Redis queuing system that scaled to hundreds of servers and 400+ tasks/sec, tooling in Rust to analyse S3 metadata and cut storage costs, and reversing a legacy distributed payments system to add redundancy. An active contributor to open-source (including improvements to a PHP Google Authenticator implementation), he brings a pragmatic focus on observability, performance tuning and developer experience. Based in the UK, Doug pairs hands-on engineering with a track record of turning complex, hairy production problems into maintainable solutions.
