A clear picture of your existing PHP application within 2–3 days – risks, security, modernization effort and roadmap as a report, at a fixed price.

Legacy Application Assessment at a Fixed Price

Before anyone spends money on a grown application, it should be clear where things stand. That is exactly what the assessment is for: a delimited package with a fixed scope, a fixed price and a result you can decide with – whether with me or with someone else.

What you get

  • Technical findings: PHP version, framework, dependencies, database, deployment, integrations – and how far all of it is from today's standard.
  • Security review: known vulnerabilities in libraries, typical weaknesses in the code (injection, XSS, session handling, uploads), configuration and access protection – prioritized by risk.
  • Stability and performance: error handling, logging, database bottlenecks, places that break under load or with growing data.
  • Business logic map: which processes depend on the application, where undocumented logic sits, what must not break under any circumstances.
  • Roadmap: recommended order of modernization in stages, with an effort estimate per stage and the honest answer to "upgrade or rewrite?".
  • Report and meeting: a written report plus a session in which we go through the results – with your management or your team if you like.

Process

  1. Short preliminary call (30 minutes): what is the application, what worries you, who uses it? Afterwards I name the fixed price.
  2. Access: read access to the repository or codebase, a copy of the database structure, access to a test or staging environment. I do not touch production systems in this phase.
  3. Analysis (2–3 working days): I use AI-assisted tools to review large codebases – evaluation and judgement are mine.
  4. Result: report, roadmap, discussion. If you then want to implement the modernization with me, the assessment fee is credited.

Who it is for

  • Companies whose developer or agency is no longer available and who need to know what they inherited
  • Management that needs a solid basis for the decision "modernize or replace"
  • Buyers or investors taking over software as part of a company
  • Teams that want a second opinion on an application before a large project starts

What the assessment is not

Not an automated scan report and not a sales pitch for a rewrite project. If the application is better than feared, the report says so. If an off-the-shelf tool is the better solution, so does that.

How I work

Three principles that apply in every project

1

Understand before building

First the short technical assessment: what is the actual problem, where is the lever, what makes economic sense? Then the implementation.

2

Build instead of forwarding

You talk to the developer who does the work – no handover chain, no black box, clear status updates and early warning about risks.

3

Hand over instead of holding on

Code in your repository, tests, documentation and a deployment process your team understands. No vendor lock-in – your system does not depend on me afterwards.

Good fit

Works well when...

  • you have a concrete business requirement that standard software does not cover cleanly.
  • you need an experienced PHP/Symfony developer who implements directly instead of forwarding tickets.
  • you run existing systems, stores or integrations that have to work together.

FAQ

Common questions before requesting

What does the assessment cost?

A fixed price that I name after the preliminary call – depending on the size of the codebase and the number of connected systems. The scope is agreed in writing beforehand; there is no additional billing.

Does the application have to be touched?

No. I work on a copy or with read access. Live operations remain unaffected.

Am I obliged to do the modernization with you afterwards?

No. The report is yours and is written so that another developer can work with it. If you continue with me, the fee is credited.

How fast is it?

After access is granted usually within one to two weeks, depending on workload. Say so in the preliminary call if it is urgent.
