Summary
🤩
Rockstar🎓
Top SchoolWesley Kim is a seasoned engineering leader with 14 years building scalable distributed systems, currently heading Observability Storage at Palo Alto Networks after Chronosphere’s acquisition. He led distributed storage and observability engineering teams at Chronosphere and platform efforts at Cash App, bringing deep operational experience from Square to production-grade metrics and telemetry systems. A Carnegie Mellon computer science alumnus, Wesley combines hands-on backend development—contributions to the widely used M3 TSDB monorepo and Cash App’s Misk framework—with team-level strategy and API design. He’s particularly skilled at refactoring core storage components and improving rules engines and downsampling pipelines, helping bridge low-level performance work with product-facing observability features. Based in New York, he pairs pragmatic engineering with a knack for untangling legacy systems into scalable, maintainable infrastructure.
