About this gig

Is your app stuck on old PHP or .NET Framework, breaking after updates, or simply too scary to touch? I've spent 20+ years working with PHP and .NET codebases, and rescuing them is one of the things I do best.


How I work:

- I start with an audit: security holes, outdated dependencies, performance bottlenecks and the riskiest parts of the code

- You get a prioritized plan in plain language: what to fix now, what can wait, and how much each step costs

- I upgrade step by step (PHP 5/7 to 8.x, .NET Framework to .NET 8) with backups and tests, so production does not break

- If needed, I migrate module by module to Laravel or ASP.NET Core instead of a risky big-bang rewrite
