What I'm looking for

I want to deepen my Databricks expertise on production lakehouse platforms. I recently passed AZ-104 and am completing the Databricks Certified Data Engineer Associate, which builds on the DP-700 Fabric certification I already hold. I'm looking for consulting work where I'm delivering across client environments rather than maintaining a single platform, the variety is where I learn fastest

I've built cloud data platforms and enterprise migrations for CloudSmiths, Old Mutual, PSG, Dentsu, and Hewlett Packard Enterprise. I design end-to-end pipelines and production-ready architectures for analytics and real-time data processing.

On Dentsu Audience Builder, I worked across Snowflake, Databricks, MongoDB, and Azure for a multi-tenant platform serving 130+ publishing partners. I also led Azure migrations, modernised ETL workflows, automated infrastructure with Terraform and Kubernetes, and mentor junior engineers on reliable data engineering practices.
