Software stack audit
Clarify your architecture. Reduce your risks. Decide what to do next.
A technical and functional audit of your stack to surface fragilities, prioritise actions, and back your investment decisions.
At a glance
- What it is
- Technical and functional audit of an existing stack: architecture, weak points, technical debt, risks, and a prioritised action plan.
- Who it is for
- CTOs or lead developers with a stack that grew fast, founders whose product works but stays fragile, teams accumulating debt, companies preparing a rebuild, a fundraise or a scale-up.
- Deliverables
- Written diagnosis, system map, prioritised list of problems, concrete action plan.
- Typical duration
- Between 2 and 10 days depending on the size of the project and the depth of analysis expected.
- How it runs
- Remote, with workshops and scoping sessions on site when the project calls for it.
- Where
- Anywhere in France remotely; on-site work in the Paris area (Île-de-France).

Who this audit is for
This audit is useful if you are:
- A CTO or lead developer with a stack that grew fast
- A founder with a product that works but feels fragile
- An engineering team accumulating debt without a clear picture
- A company preparing a refactor, fundraise, or scale-up
Concrete warning signs
You recognise at least one of these symptoms:
- Shipping new work keeps getting slower
- You fear breaking production on every deploy
- The code is hard to understand or change
- The architecture no longer fits the current product
- Performance is unstable or degrading
- Critical dependencies are poorly controlled
- No one has an end-to-end view of the system
In that case, you likely have a structural problem, not “just” a code problem.
What I actually do
I run a full-system audit using a pragmatic approach from real engagements on complex systems.
1. Targeted code review
- anti-patterns
- excessive coupling
- unnecessary complexity
- testability
2. Architecture analysis
- monolith vs microservices vs hybrid
- separation of responsibilities
- flow design (API, messaging, real-time)
3. Risk assessment
- scalability
- stability
- critical dependencies
- failure points
4. Performance & real-world behaviour
- APIs
- frontend
- mobile where relevant
- latency and bottlenecks
5. Technical debt
- clear mapping
- prioritisation (what truly blocks vs what can wait)
What you get (deliverables)
Not a theoretical report.
A structured document you can use immediately:
Clear diagnosis
- strengths / weaknesses
- critical areas
- overall risk level
System map
- current architecture explained simply
- key flows identified
Prioritised issue list
- ranked by business impact
- not by “technical tidiness”
Concrete action plan
- quick wins
- structural actions
- a realistic roadmap
Goal: help you decide quickly and correctly.
How I work
Pragmatic, not academic
I’m not trying to make your system “perfect”. I’m trying to make it:
- understandable
- stable
- evolvable
- controlled
Decision-oriented
Every recommendation answers a simple question: “Is it worth the cost right now?”
Low-risk refactoring
No “big bang” rewrite.
- progressive improvement
- risk reduction
- alignment with your product reality
Cross-functional view
Technical + product. I don’t only look at code, but also:
- how the product evolves
- how teams work
- where the real blockers are
Expected outcome
By the end of the audit, you should:
- understand your system
- know where the risks are
- know what to do first
- be able to explain your architecture to someone else
And above all: stop flying blind.
FAQ
How long does a software stack audit take?
Between 2 and 10 days depending on project size and the depth of analysis required.
Do you need full access to the code?
Yes, ideally. A partial audit is still possible with: documentation limited access workshops with the team
Can you implement the recommendations?
Yes. I can support or reinforce your team for: refactoring structural work rolling out good practices
Is this suitable for an early-stage project?
Yes, especially then. An early audit helps avoid: costly structural mistakes technical debt that spirals out of control
Do you always recommend refactoring?
No. Sometimes the best decision is to do nothing, or to work around the problem intelligently.
Does this page address searches like “application technical audit” or “software architecture audit”?
Yes. The audit covers the application stack, architecture, technical debt, and risks, with deliverables prioritised by business impact, not jargon.
