Database
Architecture
A slow query or a poorly structured schema can quietly undermine an otherwise well-built application. I design databases that are fast to query, easy to maintain, and built to scale with your data.

Most application performance problems are database problems. Getting the foundation right is cheaper than fixing it later.

Schema designed
for the long run
Database decisions made early are the hardest to change later. A schema that made sense for a hundred records starts to cause real problems at a hundred thousand — and by then, refactoring it is a major project in itself.
I approach data modelling by understanding how your data grows and how it gets queried — not just what it looks like today. The result is a structure that performs well under load, supports the queries your application actually needs, and stays maintainable as requirements change.
For existing applications showing signs of database strain, I audit the schema and query patterns, identify the bottlenecks with the highest impact, and work through them without disrupting a running system.
Schema Design
Normalised, well-structured schemas that model your domain accurately — with the right relationships, constraints, and data types from the start.
Query Optimisation
Slow queries identified and rewritten. Indexes added where they have real impact. Execution plans analysed to remove the bottlenecks costing you the most.
Scalability Planning
Data architecture that anticipates growth — partitioning strategies, read replica patterns, and caching layers introduced before performance becomes a problem.
Migration Strategy
Safe, reversible schema migrations with zero downtime. Changes applied incrementally so a running application is never put at risk.
