I will design or optimize your mysql database and slow queries

A slow database can make a fast application feel broken. I find out why and fix it, with numbers to prove the difference.

I am a senior developer with 15+ years of MySQL experience, including 11 years owning schema design, migrations and query optimization for a Google-acquired cloud billing platform with high-volume tables.

What I do:

• Diagnose and fix slow queries using EXPLAIN, proper indexing and query rewrites
• - Design clean schemas for new projects: tables, relations, constraints, migrations
• - Untangle locking problems and deadlocks
• - Review your existing schema and deliver a prioritized list of fixes
• - Plan safe data repairs and migrations on live databases

Every delivery includes before and after timings, so you see exactly what improved and why.

Not sure if your database is the problem? Send me the symptoms and I will tell you honestly whether this gig will help.
