Production audits
and stabilisation.

I investigate production systems to understand what is going wrong, what could fail next, and what needs attention first.

That can mean an ongoing product, an inherited codebase, or an AI-built system approaching launch. The result is a written report your team can act on, with or without me.

01 / Situations

When to bring me in

  • An ongoing product

    Changes are getting harder, failures keep returning, or the team needs a clearer view of the risks.

  • An inherited system

    The original team has left, documentation is thin, or nobody can explain how the deployed parts fit together.

  • An AI-built product

    The demo works, and you need to know how it behaves under real users, permissions, data and failure.

  • A launch or growth decision

    You need to know what must change before more customers depend on the system.

  • Technical due diligence for an acquisition is another use case. See the diligence sample

02 / Deliverables

What you receive

PRODUCTION DIAGNOSTICEXTRACT / 03

Illustrative extract. Fictional company; all findings and evidence invented.

Finding & urgency

Deploy pipeline lacks reliable health checks and rollback

Finding 3 · Urgent

Supporting evidence

Observed symptom
A deployment left the application degraded until a manual revert.
Evidence
The deployment check accepted running tasks without establishing that they could serve application traffic.

Recommended action

Fix
Add a health check for DB, Redis and a critical downstream dependency, and require CI smoke tests before declaring deploy success.
Effort
2 to 3 days. The memo names this the highest-impact fix.

Client feedback

An outstanding backend and infrastructure audit that exceeded expectations in both depth and clarity. The report was not just a surface-level review: it included clear identification of key issues, root causes, and a well-structured, prioritized execution plan. Communication was smooth, professional, and efficient throughout the entire process, with strong ownership, technical expertise, and a results-driven mindset. I would confidently recommend her to anyone looking for a high-level backend or infrastructure expert.

04 / Background

Experience

My engineering work spans commerce platforms, integrations and migrations, SaaS backends, and interfaces used to operate those systems. It has involved application code, data models, AWS infrastructure, deployment and testing.

That delivery experience is what the review draws on: where a change reaches, what it depends on, and how to check whether it worked.
