Mysql
Architecture.

MySQL powers the data layer of applications where relational integrity, transactional safety, and query performance are non-negotiable. I design normalized database schemas, write optimized queries with proper indexing strategies, and implement connection pooling patterns that prevent the performance degradation common in rapidly scaling applications. My MySQL architectures include migration workflows for zero-downtime schema evolution, read replica configurations for high-traffic systems, and parameterized query patterns that eliminate SQL injection at the architectural level. For founders building SaaS platforms, marketplaces, or data-intensive applications, a properly architected MySQL layer is the difference between a system that scales and one that collapses under load.
