Common signs: slow pages, high database CPU and timeouts. Usual causes: missing indexes, N+1 queries and inefficient SQL. What we do: find slow queries, add indexes and rewrite queries. What you get: faster queries with before and after times.
Our database index and query tuning finds the queries slowing your app down and fixes them with the right indexes, rewritten SQL and fewer round trips. A Codersarts database engineer reads the query plans, makes targeted changes and shows the before and after times. Fixed price from $199 with 1-day delivery.

What Is Query Tuning?
Query tuning makes database queries faster by changing how they run. The main tools are indexes, which let the database find rows without scanning whole tables, and rewrites, which remove unnecessary work. Tuning is guided by query plans that show exactly where the time goes.
Signs You Need Query Tuning
Pages or APIs slow down as data grows
Database CPU is high at normal traffic
Queries time out
Your ORM makes hundreds of queries per page
Reports take minutes to run
Why Queries Get Slow
Missing indexes
Full table scans on large tables.
N+1 queries
One query per item instead of one for all.
Inefficient SQL
Unneeded joins, sorts and wildcards.
Deep pagination
OFFSET on large tables gets slower each page.
Quick Checks You Can Try First
Turn on slow query logging or pg_stat_statements.
Run EXPLAIN on your slowest query.
Check whether filter and join columns have indexes.
Look for loops that run a query per item.
If the problem remains, our engineers take it from there.
How We Tune Your Database
Find. We list the slowest and most frequent queries.
Analyze. We read query plans to find the cause.
Index. We add or adjust indexes.
Rewrite. We rewrite queries and fix N+1 patterns.
Measure. We compare before and after times.
Report. We explain each change.
What You Get
The slowest queries identified
Indexes added or improved
Rewritten queries and N+1 fixes
Before and after timings
Notes for future queries
Example result (illustrative)
A dashboard query on a 2-million-row table took 4.8 seconds. Adding a composite index and removing an unnecessary sort cut it to 35 ms. Fixing an N+1 pattern on the same page reduced queries per load from 120 to 4.
What Is Included and Not Included
Included | Not included |
|---|---|
Up to 10 queries | Tuning every query in a large app |
Indexes and rewrites | Schema redesign (separate task) |
Before and after measurements | Hosting changes |
One revision round | Ongoing monitoring |

Who This Is For
Apps slowing down as data grows
Teams with high database bills
Dashboard-heavy SaaS products
Apps using ORMs without query review
What We Need From You
Database read access or slow query logs
Repository access
The slowest pages or endpoints
A staging copy if possible
Code and data privacy
We sign an NDA on request, work with the least access needed, and never keep copies of your data after delivery. You own all code, configuration and notes.
Key Terms Explained

Full table scan: reading every row to find matches
Common Mistakes We Avoid
Adding indexes on every column
Tuning without measuring
Ignoring write costs of extra indexes

Frequently Asked Questions
How much faster will queries get?
It depends, but missing indexes often give 10x to 100x improvements on large tables.
Will indexes slow down writes?
Slightly. We only add indexes that real queries need.
Do you tune ORM queries?
Yes, including Prisma, Sequelize, TypeORM, Django ORM, SQLAlchemy and ActiveRecord.
Can you tune MongoDB?
Yes, including indexes and aggregation pipelines.
