Summary
👤
Senior🎓
Top SchoolMarcos Oliveira is a Principal Software Development Engineer with 15+ years building resilient distributed systems, SRE tooling, and backend APIs across companies like Workday, Coupang, PlayStation Network, and Zendesk. He is polyglot and pragmatic—shipping production software in Go, Rust, Deno, Ruby/Rails, Erlang/Elixir and working with both structured and unstructured datastores to solve business problems. He’s equally comfortable deep-diving into low-level automation and operational concerns (systemctl integration, replication topology control) as he is shaping team strategy and mentoring engineers. An early adopter of Go who evangelized it at Sony, he also contributes to notable open-source tools—improving Go support in the popular pre-commit hook and enhancing MySQL replication management in Orchestrator. Based in Dublin, California, he blends hands-on engineering with project leadership and an unusual longevity in programming (since the Z80 era), which informs a pragmatic, tool-for-the-task approach.
