Schema and data modelling
Tables, relationships, constraints and indexes reflect the business rules so correctness lives in the data layer, not only in application code.
The database is where a product's promises become permanent.
What the work involves
The database is where a product's promises become permanent. We design schemas, plan migrations, tune slow queries, secure access and make backups restorable so growth does not turn ordinary changes into risky operations. The work is documented for the developers and operators who will own it next.
Tables, relationships, constraints and indexes reflect the business rules so correctness lives in the data layer, not only in application code.
Schema and data changes are staged, measured and reversible, with compatibility steps where the application cannot stop for a one-shot migration.
Execution plans, indexes, connection behaviour and expensive access patterns are measured before changes are made and verified afterwards.
Automated backups only count when they restore. We define retention, recovery objectives and a tested path back from common failure scenarios.
Least-privilege database roles, encrypted connections, secret handling and audit visibility protect production data from casual access.
Capacity, slow queries, locks, replication, failed jobs and backup status become useful alerts before they become customer-facing incidents.
How it works
Every database management project moves through four clear stages. You see the work taking shape instead of waiting for a final reveal.
We review schema, size, workload, slow-query evidence, backup state and access through the least invasive route available.
Findings become a written plan separating correctness, availability and security issues from optional optimisation work.
Approved migrations and tuning are tested away from production, then applied in controlled stages with backups and rollback criteria.
Performance, data integrity, backup status and monitoring are checked after the change, with a clear record for your team.
