About Jamie

I am an experienced Data Engineer specialising in building scalable and reliable data pipelines. I am capable of transforming raw data into structured, usable assets for analytics and business use. With a strong foundation in Python, SQL and ETL workflows, I help organisations streamline their data architecture and unlock value from their data.

My core expertise includes:
  • Developing and maintaining ETL/ELT data pipelines
  • Designing data ingestion and transformation solutions
  • Working with relational and NoSQL databases
  • Automating data workflows with Python and orchestration tools
  • Collaborating with analytics teams to support reporting and insights

I have successfully delivered projects in data integration, and performance optimisation, whilst working effectively with distributed teams and cross-functional stakeholders. I focus on high-quality, efficient, and maintainable solutions that support both immediate business needs and long-term growth.
