I will optimize sql queries, fix slow databases, and design schemas in postgresql
FullStack Developer, Software Engineer
Über diesen Service
Is a slow database crashing your app, spiking your server CPU to 100%, or causing timeouts?
I analyze query execution plans down to the disk I/O and buffer level to diagnose root-cause bottlenecks and speed up your database by 10x to 1,000x.
What I Diagnose & Fix:
- Deep EXPLAIN (ANALYZE, BUFFERS) Analysis: Eliminate costly Sequential Scans and Disk Hash Aggregates.
- Advanced Indexing: Composite B-Tree Indexes, Partial Indexes, and non-blocking CREATE INDEX CONCURRENTLY scripts.
- ORM Tuning: Eliminate the N+1 Query Problem in Prisma, Django, SQLAlchemy, and TypeORM.
Send me your slow query today to get started!

FAQ
What information do you need to optimize my query?
Please provide the SQL query, the database engine/version, the approximate row count of involved tables, and if possible, the output of EXPLAIN (ANALYZE, BUFFERS) query;
Do you need direct access to my live database server?
No, direct server access is never required. You only need to share the table schema DDL and query execution plan. I provide safe, non-blocking SQL scripts you can run yourself.
Will adding indexes lock my database tables during production hours?
No. I always provide non-blocking migration scripts (e.g. CREATE INDEX CONCURRENTLY in PostgreSQL) that execute safely under live traffic without locking reads or writes.
