Hanzo Hasashi

Senior Infrastructure Engineer / Senior SRE focused on building and operating reliable, secure, production platforms.

Senior SRE Focus

  • Reliability architecture: SLO/SLI design, error-budget policy, and service risk management
  • Observability at scale: metrics/logs/traces, actionable alerting, and incident signal quality
  • Incident operations: on-call excellence, runbooks, game days, and postmortem-driven remediation
  • Infrastructure as Code platforms: Terraform/OpenTofu/Terragrunt patterns for safe multi-environment delivery
  • Production hardening: security controls aligned with uptime, resilience, and operational simplicity

Current Track

I am optimizing for principal-level SRE and platform engineering roles where reliability, performance, and security must all hold under production pressure.

Selected Work

Production-style AWS platform lab with network/compute/cache/database/storage modules, Terragrunt composition, and provider internals work in Go.

secure-infra-roadmap
Public roadmap for platform reliability, security, and infrastructure maturity.
