Debugging and root-cause analysis
Reproduce the problem, trace it through logs and code, and identify the actual cause — not just where the error surfaces.
Software debugging, maintenance and performance optimization
We find why an application fails or slows down, fix the cause rather than the symptom, and help keep it stable — whether we built it or not.
Signs this is the right service
- The same bug keeps coming back after each fix
- Errors appear in production but not locally
- Pages, queries or background jobs have slowed down
- Small changes break unrelated parts of the app
- The original developer is no longer available
- Dependencies are outdated and updates feel risky
What the work covers
Performance optimization
Measure first, then remove the bottlenecks that matter: slow queries, heavy pages, inefficient code paths.
Stabilisation and technical debt
Targeted refactoring, tests around fragile areas and dependency updates that make future changes safer.
Ongoing maintenance
Agreed, recurring support for an existing application: fixes, small enhancements and updates.
How an investigation runs
01
Access and reproduce
We agree on access, then reproduce the issue in a safe environment.
02
Diagnose
We trace the cause and explain it to you, with options and trade-offs.
03
Fix and verify
The agreed fix is implemented and tested, with checks added where practical.
04
Document
A written summary of what was found, changed and recommended next.
What you receive
- A plain-language explanation of the root cause
- Code changes in your repository, reviewed and tested
- Before-and-after measurements for performance work
- Recommendations for risks we noticed along the way

Questions about this service
All questionsCan you guarantee the bug will be fixed?
We can’t promise an outcome before we’ve seen the system. We can promise a clear explanation of what we find, and we’ll tell you early if a fix needs more work than expected.
Do you need full access to our systems?
Only what the task needs. We’ll ask for the minimum access required — often a repository and a staging environment — and agree on it with you first.
Will you rewrite our application?
Rarely. Fixing and stabilising what exists is usually faster and less risky. If rewriting a specific part is justified, we’ll explain why and let you decide.
