Database Design

Your database schema is the most important architectural decision in your application. It determines how fast your queries run, how consistent your data stays, and how easily you can add new features.

A bad schema leads to N+1 queries, data duplication, missing indexes, and eventually a rewrite. A good schema makes your application faster, your code simpler, and your life easier.

Whether you're using MongoDB for flexible documents or MySQL for relational data, the principles are the same: understand your access patterns, normalize appropriately, and index strategically.

Schema design and data modeling. I model your data based on how your application actually uses it. Read-heavy? Denormalize for performance. Write-heavy? Normalize for consistency. Every decision is intentional.

Query optimization. Slow queries are usually a schema or indexing problem, not a hardware problem. I analyze your query patterns and add the right indexes, projections, and caching layers.

Migrations and scaling. Need to move from one database to another? Restructure an existing schema? Shard your data across multiple servers? I handle the migration without downtime.
