Cloud
Cloud that is designed, secured, and paid for on purpose. We cover public, private, and hybrid architecture, migrations that don't break production, workload protection, and the cost discipline that keeps a cloud bill from quietly doubling. The goal is the same one we bring to client engagements: resilient systems you can reason about.
What cloud covers
Architecture & migration
Public, private, and hybrid design, landing zones, and migrations that move production workloads without downtime.
Cloud security & posture
CSPM/CNAPP, workload protection, and identity hardening across AWS, Azure, and GCP so misconfigurations are caught before they're exploited.
Cost & operations
Right-sizing, FinOps discipline, and day-2 operations that keep both the bill and the risk under control.
