Elizabeth Waeni Mutisya

Hi, I'm Elizabeth.

I lead platform work that turns complexity into trust.

I'm a product leader specializing in platform governance and security. I turn complex identity policies, permissions, and authorization requirements into accountable systems that help developers move faster without bypassing governance.

About

From Developer to Product Leader

Elizabeth studied Informatics and Computer Science at Strathmore University and began building systems and websites at Uwezo Wetu College. Internships in Microsoft Authenticator and hybrid identity connected that engineering foundation with the security-sensitive experiences people and organizations rely on.

Since July 2023, she has worked as a Technical Product Manager across Microsoft Graph, OData, and Microsoft Services App Management and Governance. She defines authorization and identity policy models, coauthors contextual access architectures, and builds self-service governance workflows with engineering teams.

Her focus is governance that works in practice: fail-closed controls, clear ownership, staged rollouts, and telemetry that catches bypasses. Her agent-security work includes leading MCP Shield, a prototype for inspecting suspicious tool behavior.

Outside work, she's an adventurer at heart. Traveling across continents, hiking new trails, discovering cultures, and planning the next expedition.

Unifying Permissions & PreAuthorization Governance

Registration and permission governance relied on slow workflows and manual support, making it difficult for developers to move through onboarding.

What I Did
  • Shipped a self-service governance platform for onboarding
  • Redesigned registration and permission governance workflows
  • Defined authorization and identity policy specifications with core engineering teams
Impact
60% reduction in onboarding time
92% SLA compliance
About 25 weekly support requests removed
Registration and permission governance reduced from five days to under five hours

Modernizing Microsoft Graph Permissions Governance

Enterprise API governance needed consistent authorization decisions across permission risk, access types, applications, workloads, and cloud environments.

What I Did
  • Architected authorization and identity policy models for enterprise API governance
  • Coauthored a contextual authorization architecture across workload, permission risk, access type, application type, and cloud environment
  • Defined fail-closed treatment for unclassified permissions, new APIs, missing ownership, and unexpected states
  • Designed governance-bypass detection for application and permission changes with staged rollout and telemetry gates
Impact
1,200+ permission records modernized
12+ workload teams involved
Rollout checkpoints at 10%, 40%, 70%, and 100% with 24-hour telemetry gates
Automatic governance tickets when checks fail

Scaling API Review Governance Across 158 Workloads

Large engineering organizations struggled to adopt a new API review process, risking fragmentation.

What I Did
  • Launched an API and permission governance process across Microsoft Graph workloads
  • Built self-service publishing and attestation automation
  • Drove adoption of the governance process within SLA
Impact
Governance process launched across 158 Microsoft Graph workloads
90% Intune adoption within SLA
50% reduction in manual validation effort

Life Beyond the Platform

12Countries & counting

When I'm not untangling platform challenges, you'll find me on a trail, at an airport, or somewhere between the two.

Ask me about navigating motorbikes in Vietnam, sunrise at the Pyramids, or getting lost in Istanbul's Grand Bazaar.
