Mandate & leadership
- Principal AI Architect and Innovation Lab Coordinator consultant at Gavi, the Vaccine Alliance, leading the AI architecture practice behind global vaccination programmes; owns the end-to-end innovation lifecycle — idea, experimentation, outcomes, stabilisation, operationalisation — as operational deputy to the Innovation Lab Lead, and leads architecture definition and deployment across the AI portfolio.
- Leads and coordinates Forward Deployed Engineers embedded with business teams to carry AI systems from prototype into production use.
- Member of the Gavi architecture board, responsible for standards, investment prioritisation, solution assurance, exception management and technology-risk decisions; set up and coordinates the Gavi Innovation Lab.
- Aligns the Innovation Lab architecture and experimentation portfolio to Gavi 6 Strategy 2026–2030 “Data Visibility & Use”, so every experiment traces to programmatic impact on global immunisation delivery.
- Established and operates the Innovation Lab’s experimental AI tooling estate on Microsoft Frontiers models in Azure — including Cowork, Copilot Claude, MS Scout and OpenClaw for agentic-AI experimentation and architecture evaluation, alongside Cursor, Lovable, Bolt, v0, Microsoft 365 Copilot, Copilot Studio and Azure AI Foundry — under defined tool-selection rules, cost guardrails and an approved/excluded tooling list.
Innovation governance & operating model
- Manages the Innovation Lab governance model, structuring innovation into three stepped streams (Ideation → Experimentation → Stabilisation) with five accountable roles, RACI ownership per activity, entry and exit criteria, and a rhythm of weekly experiment reviews, monthly idea reviews and quarterly approval sessions.
- Manages dual-mode execution governance for experiments: in-house delivery with mandatory Platform Architect validation of capacity, skills, security guardrails and environments, and external delivery by vendors, startups and academia through a four-phase collaborator workflow with capability-based assessment, compliance checks and post-experiment partner evaluation.
- Managed the Innovation Lab KPI framework across Innovation & Delivery, Business Impact and Engagement.
- Supported the conversion of the Innovation Lab from a project team into a consumable internal service, defining five entry pathways by idea maturity, a guided intake routed on maturity, urgency and strategic alignment, and three graduated support levels; participated in the launch of the new Innovation Lab Office.
- Leads change management for innovation adoption, codifying the Lab’s operating values (human-centric, inclusive, transparent, business-grounded, outcome-oriented, open, ethical) and the adoption mechanics behind them: executive sponsorship, a distributed network of local advocates, continuous field feedback loops and evidence-based impact narratives.
- Maintains the Innovation Lab vendor capability matrix, benchmarking six global delivery partners across five domains — AI & Machine Learning, Blockchain & Digital Assets, Immersive & Emerging Tech, Automation & Data, Research & Innovation — as the mandatory input to external-executor selection.
Enterprise AI platform & governance
- Operationalised AI governance controls covering data leakage, agent proliferation, cost overruns, prompt injection, hallucination and shadow AI, with per-agent monthly credit limits and threshold alerting, DLP connector policies blocking third-party connectors, and monitoring across Power Platform Admin Center, Microsoft Purview and Microsoft Sentinel, reported monthly to the AI Steering Committee.
- Leads AI enablement through a three-tier training architecture, a curated prompt library, an intranet AI Self-Service Hub and an organisation-wide AI Community of Practice with departmental champions — targeting 80%+ awareness-training completion and 70%+ monthly active Copilot users in year one.
- Established the reusable reference architecture for grounding Copilot agents in enterprise knowledge — SharePoint → Azure Blob → Snowflake → Azure AI Search vector index → Power Automate → Azure OpenAI → Copilot in Teams/SharePoint — secured with Entra ID RBAC, Key Vault and Purview DLP, with mandatory citation traceability and token-consumption cost controls.
- Develops AI and solution architectures in full collaboration with the information-security and compliance function, as a formal pre-review and clearance gate rather than an after-the-fact sign-off; controls such as Entra ID SSO, least-privilege service access, audit logging of queries, responses and data access, restricted-content protection, Key Vault, PIM, RLS and Purview DLP are specified at design time.
Solution architecture delivered
- Designed the secure Azure architecture for Gavi’s confidential Ombuds, Staff Counsellor and Ethics & Compliance case- and visitor-management platform: three segregated functions on Azure App Service over Azure SQL with Transparent Data Encryption and customer-managed keys in Key Vault, row-level security, Entra ID app roles enforced per request, managed identity as sole database principal and Privileged Identity Management with no standing admin access.
- Covered visitor and case lifecycles, category taxonomies, referral routing and service metrics under hard confidentiality controls — an immutable audit trail, a strict “Chinese wall” between functions, visitor numbers with no names stored and a <5 anonymisation threshold on all reporting — modelled in C4 and validated by an independent penetration test before go-live.
- Designed the Azure architecture extending Gavi’s Programmatic Dashboard from reactive reporting to predictive early warning, forecasting country × vaccine stock-buffer breaches 6–12 months ahead — integrating SAP, UNICEF SD/Thrive360 and VaxNeed into Azure SQL and a row-level-secured Power BI model, with forecasting on Azure Machine Learning and grounded narrative generation on Azure OpenAI behind an API Management LLM gateway.
- Coordinated architecture-board acceptance of the Governance Bot: a permission-aware knowledge assistant for audit-committee, board and governance-decision queries in Teams and SharePoint on Azure AI Foundry, with an eight-metric production-approval framework — answer accuracy ≥90%, citation coverage 100%, fallback precision ≥95%, access-control integrity 100% — so an AI service is not approved on technical completion alone.
- Defined a multi-tier Governance Copilot ecosystem separating the user-facing Governance Bot, a Governance Knowledge Hub and a Power Automate + Azure OpenAI Query Executor, with Azure Blob ingestion, Azure AI Search vector indexing, Entra ID single sign-on and Azure Monitor / Log Analytics monitoring of latency, token usage and errors.
