Efosa Omigie
15+ years building the data systems that hold under regulatory weight — across the NHS, central government, and regulated enterprise. I design the architecture, then stay to deliver it: Lakehouse platforms, AI/agentic systems, and the governance that lets them ship in environments where failure isn't an option.
Practice areas
Data & Cloud Architecture
Enterprise data architecture and Lakehouse platforms built to hold up under audit, scale, and sector regulation.
AI & MLOps
GenAI and agentic systems taken from prototype to production, with the MLOps and feature-store foundations to keep them maintainable.
Data Warehouse Delivery
Star-schema warehouses and tabular models that make reporting fast, trustworthy, and easy to extend.
Power Platform
Low-code delivery for public sector teams — apps, automation, and reporting on a governed Dataverse foundation.

Portfolio
Lakehouse Modernisation
2025 – 2026Data architecture for a national infrastructure operator, moving legacy data estates onto a governed Databricks Lakehouse to support regulatory reporting and analytics at scale.
GenAI & Agentic Systems
2025Design and delivery of RAG-based GenAI systems and early agentic architectures, with the MLOps and feature-store foundations needed to move them from prototype to production.
National ERP & Enterprise Architecture
2024 – 2026Enterprise data architecture and assurance design across major public-sector and infrastructure transformations, defining canonical models and integration standards for national Oracle Cloud and Dynamics 365 ERP migrations. DevSecOps and CI/CD automation cut release cycles from 14 days to 3 hours.
Data Standards & Metadata Governance
2022 – 2024Built centralised Collibra metadata repositories as a single source of truth for data definitions, lineage, and catalogue standards, with automated metadata quality checks that lifted metadata quality by approximately 30% over nine months.
ICB Data & Systems Leadership
2022 – 2024Led a unified data vision spanning workforce analytics, assurance, and governance for an Integrated Care Board; chaired the central data-governance committee and introduced predictive workforce planning models to forecast demand and mitigate staff shortages.
Trusted Research Environment
2020 – 2022Directed architecture for the NHS's national Trusted Research Environment — secure data environment design on AWS and Databricks meeting GDPR and NCSC controls, with Collibra-based metadata and lineage frameworks supporting research-data transparency.
Business Analysis & Data Migration
2022 – 2023Led business analysis and data migration of the Student Information System to Ellucian, defining a migration strategy covering data retention, lineage documentation, and quality validation, alongside stakeholder requirement capture and sign-off.
Power BI & Visualisation Modernisation
2015 – 2024Delivered organisation-wide and regional BI reporting — from QlikView and SSRS estates modernised into Power BI, to a national NHS workforce MI strategy and a system-wide regional analytics hub spanning multiple providers.
Public Sector Power Platform Delivery
2020 – 2021Low-code applications, workflow automation, and reporting built on a governed Dataverse foundation, delivered across local government and a major central government infrastructure programme.
Experience
15+ years across data architecture, analytics engineering, and delivery leadership, most recently through engagements with National Grid UK, Cohesive/Bentley Consultancy, and Altera Healthcare.
The majority of this experience sits within the NHS and wider public sector — including national NHS bodies, integrated care systems, central government infrastructure programmes, and local authorities — alongside regulated enterprise clients.
All engagements are delivered through Efomie Global Consulting.
