Schema design, index and query tuning on PostgreSQL and MS SQL Server — measured before and after.
Database optimization is changing the schema, the indexes, and the queries on the evidence of measurement, so that the same hardware answers faster. GG Tech's Database Engineering & Optimization service starts from the slow-query log and wait statistics rather than opinion, designs the schema and indexes, rewrites the expensive queries, and proves the difference under load. We work on PostgreSQL and MS SQL Server.
| Typical team | 1 database engineer + 1 developer |
|---|---|
| Calendar band | 2–8 weeks |
| Phase split | 30% measurement & profiling · 35% schema & indexes · 25% query rewriting · 10% load verification |
What grows the budget
Signs of underbudgeting
These are GG Tech Teknoloji planning bands, not a quote — we do not publish prices. Every project is different, so the bands are deliberately wide; they assume a senior, focused team and typical scope, and your project is estimated individually.
Measurement first
Slow-query log, wait statistics, execution plans. Nothing is changed before there is a baseline to compare against.
Schema and index design
Normalization decisions, partitioning, the indexes that are missing — and the ones that only cost you writes.
Query rewriting
Expensive queries are rewritten and re-measured one at a time, so every change carries its own before/after number.
Verification under load
The gain is confirmed at production data volume and concurrency, not on an empty test database.
What we deliver
