Review before investing further

Technical backend, API and architecture audit

I review an existing system to separate demonstrable problems from technical preference and turn the evidence into a useful order of work.

Problem it solves

Know what to fix, measure and leave alone

A useful audit is not an automated checklist or an excuse to rewrite.

It connects technical evidence with operational impact, change cost and defensible priority.

Investment decision

When it is worth it

The system fails or slows down without a clear cause.

A rewrite or migration proposal needs an independent view.

APIs are difficult to change or integrate.

A technical plan is needed before budgeting or hiring.

Frequent work

Common use cases

Scope should start with an observable problem and a clear way to verify the improvement.

Backend

Errors, boundaries, persistence, concurrency, observability and tests.

APIs

Contracts, validation, idempotency, security and evolution.

Architecture

Coupling, boundaries, dependencies and operational complexity.

Delivery

Build, configuration, release, rollback and production diagnosis.

Possible scope

What it can include

  • Evidence-backed findings map.
  • Priority by impact, effort and risk.
  • Immediate actions and decisions that require more data.
  • Phased plan ready for estimation or execution.

Working criteria

What to avoid

  • Auditing without a business or technical question.
  • Confusing style with material risk.
  • Proposing new technology without transition cost.
  • Delivering a long list without execution order.

Execution

How I work

  1. We agree the questions and review scope.

  2. I read the relevant code, configuration and documentation.

  3. I verify findings and discard preferences without impact.

  4. I deliver prioritized conclusions and explain their context.

Frequently asked questions

Does the audit include code changes?

Not by default. Diagnosis and priorities come first; execution can be scoped separately.

What access do you need?

It depends on scope: repository, documentation, non-secret configuration, diagrams, metrics or incident examples.

Can I use the report with another supplier?

Yes. The conclusions should remain understandable and useful regardless of who implements them.

Next step

Tell me which decision needs evidence

The review can focus on one API, a performance issue, a migration or the wider system.

Before you close this

Would you like me to look at your case before you go?

Share the context. I will tell you clearly whether I can help and what the most sensible next step would be.
