A focused specialist consultancy for complex infrastructure.
Grade Systems exists to help organizations make sound infrastructure decisions, deliver difficult transitions, and build systems that remain dependable after the project is over.
Enterprise infrastructure is where strategy meets operational reality. Grade Systems works in that space — helping teams modernize without losing control of reliability, recovery, or the people who operate the platform.
The company combines architecture with hands-on delivery. That means understanding the target state, but also the migration paths, dependencies, governance, supplier relationships, and runbooks that make change possible.
Engagements are intentionally senior and focused. Grade Systems does not present itself as a large agency; it is a founder-led practice that brings experienced technical leadership to the moments where clarity and accountability matter.

João is an experienced infrastructure technical leader with hands-on expertise in virtualization, enterprise platforms, disaster recovery, cloud transformation, automation, and complex production environments.

Every engagement is grounded in transparent decisions, explicit trade-offs, and outcomes that can be verified by the teams responsible for the platform.
Start with the current state
Before recommending change, understand the platform, its dependencies, and its operational constraints.
Make risk visible
Surface assumptions, lifecycle concerns, recovery gaps, and decision points early enough to act.
Design for ownership
Leave behind useful architecture, documentation, and operating clarity — not dependency on a consultant.
Prefer durable value
Favor changes that improve the organization’s ability to operate and adapt over time.
