Database architecture that keeps your app fast as your data grows

Most slow apps have a data problem

When a web application gets slow, the database is usually involved: a missing index, a query that loads ten thousand rows to display ten, a schema designed for the first version of the product that now fights every new feature. Database architecture work fixes the structure underneath, so the application stays responsive and your data is in shape for reporting and AI projects later.

The work covers PostgreSQL, MySQL, MongoDB and Redis, including managed versions of each on the major cloud providers.

What the engagement involves

For new products, it starts with data modelling: the entities your business cares about, how they relate and which queries matter most. For existing systems, it starts with measurement, using slow-query logs and query plans to find where time is actually spent. Fixes might be new indexes, rewritten queries, caching with Redis or a revised schema rolled out through careful migrations.

Alongside performance, we set up backup and point-in-time recovery, role-based access so each service only sees what it needs, and reporting pipelines that keep analytics queries off your production database. Work typically takes two to eight weeks. Changes are tested against a copy of production data before release, so performance gains are measured rather than assumed. You receive documentation of the schema, the reasoning behind key design choices and a short runbook for routine tasks such as restoring a backup or adding a read replica. That documentation matters more than it seems: the next developer to touch the database will understand why it looks the way it does instead of working around it.

When to call in database help

It is worth doing before a major launch, when pages or reports are getting noticeably slower, when you are moving between databases, or when you want to feed business data into dashboards or AI tools.

If the application only stores a few thousand records and performs well, a full architecture review is probably unnecessary. A short health check of backups and access control may be all you need. A health check usually takes days rather than weeks and tells you whether deeper work is needed.
