What I'm looking for

I’m looking to lead end-to-end data platform and analytics engineering work—prioritising reliability, data quality, CI/CD ownership, and self-service BI—while aligning technical delivery to business outcomes and mentoring high-performing teams.

I’m a Data Engineering Lead with 7+ years delivering production data infrastructure at scale across complex, data-intensive organisations. I’m fluent across the modern data stack—OLAP warehousing and lakehouses, big data platforms, and analytics engineering—to turn raw data into business-ready outcomes.

I’m a strong analytics engineering practitioner with dbt as a core tool, delivering transformation pipelines end-to-end. I build transformation layers from Spark-based distributed processing and SQL-native modelling to SSIS-orchestrated ETL, stored procedure logic, and Python-driven pipeline automation.

I lead delivery of self-service reporting layers and own CI/CD for data teams, with a focus on reliability, data quality, and safe operations. In my recent work, I drove an 80% reduction in reporting turnaround time through pipeline automation and maintained 99.9% pipeline and reporting uptime across critical workflows.

I also take ownership of the hard parts—debugging orchestration failures at the infrastructure level and supporting real-time, secure data systems. I enjoy aligning data engineering capabilities with organisational goals and mentoring teams to deliver scalable solutions that help business teams move faster with trustworthy metrics.
