Platform transformation across healthcare, energy, education and public sector. The organisational side of the story, not just the technical one.
Inherited a platform that was expensive, fragile and architecturally misaligned with how the business actually operated. The challenge wasn't purely technical — it was understanding the organisation well enough to design something that would outlast the engagement.
Led business process analysis workshops to define canonical Data Vault and dimensional models aligned to real operational workflows. Established IaC, CI/CD, testing and documentation standards. Drove data literacy across the business — SQL upskilling for data scientists, QuickSight self-service for C-suite, data modelling workshops for engineers.
Joined an established AWS and DBT environment where the codebase had grown organically without a clear architecture. Failure rates were climbing, costs were high, and the engineering team had limited visibility into why.
Conducted systematic architectural reviews to surface inefficiencies. Re-orchestrated the codebase to enable greater parallelism and automation — significantly reducing failure risk. Mentored engineers on AWS and Python alongside the technical work.
Greenfield platform build to consolidate hundreds of client databases into a single governed analytics platform. The technical challenge was significant — but the harder problem was designing an architecture that could serve hundreds of different clients without becoming a maintenance burden.
Built a unified Redshift star-schema warehouse with a QuickSight customer analytics interface, enabling client self-service analytics at scale.
Hired to take over a system built by contractors that the organisation couldn't maintain or extend. The immediate technical problem was significant — but the more important challenge was building internal capability so they didn't end up in the same position again.
Designed AWS ingestion framework and Snowflake warehouse architecture from inception. Hired and onboarded engineers, establishing team standards and engineering culture from scratch.
