Summary

Senior🎓
Top SchoolAndrew Sison is a Site Reliability Engineer with nine years of experience building resilient cloud-native systems and reducing operational toil at scale. He has driven reliability improvements across healthcare and SaaS—automating manual processes with Python and SQL, provisioning observability and alerts via Terraform, and improving MTTR for multi-tenant services. Comfortable in Go, Python, C#, Java and IaC tools like Ansible and Terraform, he bridges software development, compiler/interpreter curiosity and platform engineering to solve both runtime and code-level reliability issues. Notably, he migrated high-volume email systems to a microservice with a sub-0.0001% failure rate and uncovered a subtle C# bug by tracing inherited-variable misuse, then prevented regressions with tests. Based in Los Angeles, he combines hands-on incident response with tooling-driven prevention to keep distributed systems healthy.
