Senior🎓
Top SchoolLuc Dang is a Senior Site Reliability Engineer with 9 years of experience building and hardening Ruby/Rails backends and AWS-hosted production systems from Vietnam. He specializes in zero-downtime migrations and upgrades—moving databases to AWS, converting columns to BigInt, and upgrading runtimes and OS versions while keeping services live. At Judge.me he improved performance across Postgres, MongoDB and Elasticsearch, built an auto-heal system tied to NewRelic/CloudWatch/Redis, and created a Slack-driven CI/CD tool that streamlines deploys, changelogs and rollbacks. Previously he led DevOps for a 5G platform that provisioned Kubernetes across cloud and bare-metal, recreating core IaaS primitives (S3, DNS, registry, monitoring) to reduce cloud dependence. He combines hands-on optimization and automation with team leadership, regularly detecting implicit issues before they impact users. Collected experience in both frontend scaffolding and deep backend reliability gives him a pragmatic full-stack perspective on resilient systems.
