FIX & MAINTAIN
Database migration and performance tuning.
Slow pages are usually slow queries. Growing databases hit limits faster than people expect. We audit, profile, and optimise databases — adding the right indexes, rewriting expensive queries, and migrating between engines (MySQL ↔ PostgreSQL ↔ MongoDB) without downtime.
Who this is for
Three patterns we see most often. If one of these sounds like your team, this service likely fits.
Engineering leads with a slow product
Pages load in 8 seconds. Users notice. The team knows it's the database but doesn't have time to fix it properly.
Companies migrating off a legacy engine
Old MySQL or Oracle setup. You want to move to PostgreSQL or Aurora. The data is critical and the downtime budget is zero.
Growing SaaS hitting database limits
Single Postgres instance is creaking. You need read replicas, query optimisation, and a real plan for the next 10x.
What you get
- Performance audit report with prioritised issues and expected impact
- Indexes added, queries rewritten, schema changes proposed and applied with care
- Migration plan for engine changes — MySQL to PostgreSQL, or to Aurora, with zero or minimal downtime
- Read-replica setup, connection pooling (pgBouncer), and caching where it earns its keep
- Monitoring dashboard so you can see query performance over time
- Runbook for future scaling steps tied to specific traffic thresholds
Our approach
How a typical database migration & tuning project moves from first call to live in production.
- 01
Profile and audit
We run real query analysis on your production database (or a representative replica). Find the worst offenders first.
- 02
Quick wins
Indexes, query rewrites, and config tuning that don't need code changes. Most projects see 30 to 70% improvement here alone.
- 03
Structural fixes
Schema changes, partitioning, archiving cold data, read replicas. Bigger lifts that need planning and rollout discipline.
- 04
Migrate (if needed)
Engine migrations done in stages — replication, dual-writes, switchover, verification. We've done MySQL to PostgreSQL multiple times.
Stack we use
Boring, proven tools that other senior developers can maintain. No exotic choices that lock you in.
- PostgreSQL
- MySQL
- MongoDB
- Redis
- pgBouncer
- AWS RDS
- Aurora
