Summary
🤩
Rockstar🎓
Top SchoolJeannette Pepin is a Senior Software Engineer with 10 years of experience building observable, cloud-native distributed systems using Go, Rust, and Python. She designs and implements reliable data pipelines, REST APIs, and Kubernetes-native services, and is fluent with Pulumi, Terraform, Snowflake, Redshift, and BigQuery. At Materialize she improved platform health by adding storage metrics and liveness endpoints to a widely used real-time SQL engine, and she’s driven observability and SLO-driven reliability across multiple SaaS/PaaS products. Her background includes leading cross-functional observability initiatives at Apptio and architecting scalable infra for Materialize Cloud, combining hands-on systems work with infra-as-code practices. Based in Boulder, CO, she pairs an M.S. in Computer Science with an early humanities training in English, which contributes to clear technical communication and cross-team leadership. Colleagues rely on her for practical instrumentation of hard-to-observe Rust services and for turning telemetry into business insights.
