Senior SRE & Lead Architect

(New York & Global Remote @ BizSafer)

Engineering Resilient Systems That Are Safe To Scale.

I operate BizSafer, a specialized Production-First Engineering Lab anchored in New York. I focus on high-availability infrastructure for platforms in North America, the United Kingdom, and Europe, delivering industrial-grade reliability through the SRE Standard.


📊 The SRE Standard (Operational Metrics)

  • 99.9% Availability Target: Engineering zero-single-point-of-failure (ZSPoF) architectures.
  • <60s MTTR: Implementing automated self-healing loops and disaster recovery protocols.
  • Sub-200ms Latency: Optimizing the "Golden Path" from database to edge delivery.

🏗️ Technical Pillars & Lab Focus

Pillar Core Stack
Infrastructure as Code Terraform / OpenTofu, Ansible
Orchestration & Scaling Kubernetes (EKS, GKE, AKS), Docker
Cloud & Edge Security AWS, GCP, Azure, Cloudflare WAF, Nginx Hardening
Observability Prometheus, Grafana, ELK Stack (Four Golden Signals)
Application Cores High-Performance Laravel, Next.js, Node.js, MySQL

🧪 Current Lab Research (BizSafer)

  • Configuration Management: Standardizing immutable infrastructure using Ansible to eliminate manual drift.
  • Centralized Logging: Engineering ELK Stack pipelines for deep-dive root cause analysis and automated restoration.
  • Automated Failover: Refactoring legacy standalone environments into high-availability clusters.
