• Develop reusable components and patterns for ingestion, transformation, validation, and monitoring.

• Prepare governed and trusted datasets for analytics, reporting, AI, and machine-learning use cases.

• Collaborate with clients and internal stakeholders to translate business requirements into practical technical solutions.

• Identify opportunities to modernise legacy processes, reduce manual effort, and improve operational efficiency.
