Database & SQL Consulting

A slow query that runs fine on a demo dataset can bring a real system to its knees at scale. We tune databases and design schemas for the load you'll actually have, not the sample data a demo gets built against. That covers indexing strategy, query optimization, and replication and backup planning across relational and NoSQL systems alike. We profile actual production query performance before touching anything, so fixes target what's really slow, not a guess. Whether it's a system that's degraded over time or a new schema being designed from scratch, the goal is the same: performance that holds as your data actually grows.

Overview

Problems that show up six months after launch

Database performance problems rarely show up in development. They show up months after launch, when the data volume is real and every query that used to be instant is suddenly not.

We do performance tuning on existing systems and data architecture design for new ones: indexing strategy, query optimization, and schema design that holds up as your data grows, not just at launch.

What's Included

What you get with Database & SQL Consulting

Query performance tuning

Finding and fixing the queries that are quietly slowing everything down.

Schema & data architecture design

Structured for how your data actually grows, not just how it looks at launch.

Indexing strategy

The difference between a query that takes 10ms and one that takes 10 seconds.

Replication & backup strategy

Data that survives a failure, tested, not just assumed to be backed up.

Database audits

An honest assessment of what's actually wrong before we touch anything.

Migration between database systems

Moving from one database engine to another without losing data integrity.

How We Work

Our approach

We profile actual query performance before recommending changes. Tuning based on assumptions instead of data usually makes things worse. That means running diagnostics against a copy of real production data, not a synthetic benchmark that doesn't reflect your actual query patterns. Indexing and schema changes are tested for their effect on write performance too, since a fix that speeds up reads but silently slows every write isn't actually a fix. Every change is applied in a way that's reversible, with a rollback plan ready before anything touches production data.

FAQ

Common questions about database & sql consulting

Our database has gotten slow over time. Can you fix it without a rebuild?

Usually, yes. Most performance problems are query and indexing issues, not fundamental architecture problems.

Do you work with NoSQL databases too?

Yes, MongoDB and Redis alongside traditional relational databases, depending on what fits the workload.

Can you audit our database without making changes first?

Yes, an audit is a standalone engagement if you just want the assessment.

How do you avoid downtime during optimization work?

Changes are tested against a copy of production data first, and applied in a way that's reversible.

Can you help us choose between a relational and NoSQL database for a new project?

Yes, the right answer depends on your actual data shape and access patterns, and we'll give you a straight recommendation rather than a default.

Do you provide ongoing database monitoring, or just one-time tuning?

Both: a one-time audit and fix, or ongoing monitoring so performance regressions get caught before they become an incident.
