Leadership

One founder. Two practices. One standard.

Calvrix is intentionally small. The people you talk to in the first conversation are the people who own your platform after. Two practices, Microsoft enterprise and cloud-native, run to one standard: the same review, the same documentation, the same on-call discipline, whichever stack your platform sits on.

Founder

Mohsin Sharif

Platform engineer. Founder of Calvrix Ltd. Holds the operating standard across both practices. The decision-maker on every architecture review and the named owner of the seven-year anchor engagement since 2019.

Practice 01 · Microsoft enterprise

Where money is the system of record.

Architecture, live modernisation, and operational standard across the Microsoft stack: .NET, Entity Framework Core, Azure-native infrastructure, payment routing, settlement-grade ledgers, long-running enterprise systems.

Practice 02 · Cloud-native

Built to be operated, not just shipped.

Architecture, delivery, and operational standard across the cloud-native stack: Kubernetes (AKS / EKS), Terraform, GitHub Actions, observability, multi-cloud platform engineering with full team ownership.
