Our old internal system is grinding to a halt

Modernise a slow, ageing business system without halting the business.

Targeted refactoring of the controllers and queries that actually hurt — instead of a risky full rewrite.

Signs this is your problem

You will recognise yourself in at least one of these

Reports take 10–15 seconds (or more) to load.
Database deadlocks happen during peak hours.
Adding features feels impossible because everything is interconnected.
The stack is old enough that hiring for it is hard.

Why it happens

The root cause, in plain language

Years of fast feature work piled on a thin foundation. Heavy controllers, missing indexes and N+1 queries compound until basic operations crawl.

Our approach

How we actually fix this

1
Profile the live system to find the actual bottlenecks (it is rarely where the team thinks).
2
Refactor the critical controllers without changing public behaviour.
3
Drastically optimise SQL queries and add proper indexing.
4
Gradually modernise the codebase under the Strangler Fig pattern.
5
Monitor database query patterns 24/7 to prevent deadlocks.

What you can expect

Outcomes our clients see

Report generation reduced from 15s to under 1s.
Zero downtime during the migration.
24/7 database query monitoring keeps performance stable as data grows.

Case study

Internal ERP rescue — slow monolithic CRM

An aging, monolithic in-house CRM was taking up to 15 seconds to load financial reports due to severe database locks. We audited the app, refactored the critical controllers, and drastically optimised the SQL queries and database indexing. Report time dropped from 15s to 0.8s.
