• Develop logical and physical data models and maintain ERDs and data dictionaries.
• Tune SQL performance (indexing, partitioning, query optimisation).
• Implement validation rules, constraints, and reconciliation checks to ensure data quality.

• Contribute to ETL/ELT pipelines and environment promotion using standardised patterns.
• Use version control (Git) and CI/CD workflows for database changes.
• Collaborate with platform/Dev Ops teams on capacity management, monitoring, and backup/recovery strategies.

• Work within a structured delivery approach (story backlog, layered delivery model, reusable components).
• Apply consulting‑grade practices such as documentation, peer reviews, test execution, and quality checkpoints.
• Participate in Agile ceremonies (stand‑ups, planning, retros).

• Partner with BAs, product owners, and downstream consumers to translate requirements into robust SQL designs.
• Support UAT, investigate defects, and resolve logic issues quickly.
• Produce runbooks, knowledge‑transfer materials, and follow governance/security standards.
