Is your MySQL database getting slower as your application grows?
I can investigate slow queries, missing indexes, inefficient joins, locking, excessive database load and other common MySQL bottlenecks in an existing production system.
Diagnose the actual cause of a slow MySQL database.
Diagnosed a MySQL database where inserts were locking for 5+ seconds. Root cause: a combination of missing indexes on the ORDER BY columns and InnoDB gap locking under high concurrent writes. Fixed with targeted indexes and a batched insert strategy.
You share slow-log/explain output and schema (or grant read-only access to a replica). I trace the bottleneck — which query, which index, which schema issue — confirm it with EXPLAIN, and return a written diagnosis with the fix order. One focused session.
MySQL performance diagnosis and a written report with prioritized recommendations. Implementation is optional and quoted separately.
Yes. The slow query log, EXPLAIN output and SHOW CREATE TABLE are enough to identify the bottleneck.
I include application/database interaction review in the diagnosis, so I can tell you whether the fix belongs in the query, the index, the schema or the calling code.
