Security
Authentication, data handling, exposed secrets, unsafe dependencies and common attack paths.

Code review & modernisation
We help teams understand inherited or ageing codebases, reduce technical risk, and modernise safely without losing the business knowledge already built into the system.
What we examine
A complete view of software health.
We do more than identify untidy code. Every finding is considered against security, customer experience, delivery risk and the commercial value of fixing it.
Performance
Slow queries, heavy bundles, inefficient rendering, caching gaps and reliability bottlenecks.
Maintainability
Complexity, duplication, test coverage, documentation and code that is difficult to change safely.
Architecture
Boundaries, integrations, scalability, deployment design and whether the system still fits the business.
Accessibility
Front-end patterns that affect keyboard users, assistive technology, readability and inclusive journeys.
Modernisation
Outdated frameworks, unsupported packages and a practical sequence for upgrades without unnecessary rewrites.
How it works
From repository to clear decisions.
A review should create momentum—not leave your team with an intimidating list of problems.
- 01
Secure access
We agree the scope, access method and confidentiality requirements, including an NDA when needed.
- 02
Independent review
We inspect the code, architecture, dependencies and important user journeys without disrupting delivery.
- 03
Prioritised report
Findings are ranked by severity, effort and business impact, with evidence and recommended fixes.
- 04
Team walkthrough
We explain the results, answer questions and agree what to fix now, next or later.
What you receive
A report your whole team can act on.
Technical detail for developers, a concise summary for decision-makers, and a roadmap that distinguishes urgent risks from sensible longer-term improvements.
- Risk rating and supporting evidence
- Recommended remediation with estimated effort
- Quick wins separated from structural work
- Optional implementation support from KIR

Ways to work with us
Choose the depth that fits your situation.
We confirm the repository, technologies and exact scope before work begins. Reviews identify and explain issues; remediation, penetration testing and compliance certification are quoted separately when required.
Mini Code Review
A focused, independent review of one agreed code area, pull request or critical customer journey.
- ✓ Code quality and maintainability check
- ✓ Obvious security and dependency risks
- ✓ Concise, prioritised findings summary
In-Depth Code Review
A comprehensive technical assessment covering architecture, code quality, security, performance and technical debt.
- ✓ Executive and technical reports
- ✓ Risk-rated findings with evidence
- ✓ Prioritised improvement roadmap
Ongoing assurance
Independent review support that becomes part of your regular engineering workflow.
- ✓ Recurring review cycles
- ✓ Release-readiness checks
- ✓ Practical team guidance
Your code remains your code.
We use least-privilege access, work within agreed boundaries and never reuse or disclose proprietary code. Access can be removed as soon as the review is complete.
Findings stay practical.
We will not recommend a rewrite simply because a newer technology exists. Advice is based on risk, value and what your team can realistically maintain.
Common questions
Before you share the repository.
Which technologies do you review?
Our strongest coverage includes JavaScript, TypeScript, React, Next.js, Node.js, APIs, databases and cloud-hosted applications. We confirm suitability before accepting the review.
Do you need full repository access?
Not always. A focused review may only require a branch, pull request or selected files. We agree the least access necessary for the scope.
How long does a review take?
Turnaround depends on codebase size and scope. After a short discovery call, we provide a clear schedule before access is granted.
Can KIR fix the issues afterward?
Yes. We can support your team, implement agreed fixes, modernise the codebase or return later for an independent validation review.
Will the review delay our development team?
It should not. We arrange read-only or isolated access where possible and keep questions focused, so normal product work can continue.
Ready for a second pair of eyes?
Know what to fix—and why it matters.
Tell us what you are building, the concern you want investigated and any release deadline. We will recommend the right review scope.
