We are looking for a software developer to update and maintain an existing application written in PHP, MySQL, and C++. This is work on a live, older codebase. The goal is to keep current behavior working while bringing the code up to date so it is easier to run, change, and support.

What you will do

- Read and understand the existing PHP, MySQL, and C++ code before changing it
- Update PHP to a current supported version and replace outdated language features, libraries, and patterns
- Review and update MySQL schemas, queries, and data access so they stay correct and perform well
- Update C++ components so they build with a modern compiler and integrate cleanly with the rest of the system
- Fix bugs, close security gaps, and improve error handling without changing how the application is supposed to work
- Add or improve tests around the parts you change
- Document setup, build steps, and anything a future developer needs to know

What you should bring

- Strong experience with PHP and MySQL on existing applications, including older codebases




- Solid C++ experience, including reading unfamiliar code and updating it safely
- Comfort working across a full stack: web or application code, database, and native components
- Careful habits: small changes, clear commits, and checks that existing behavior still works
- Clear written communication about what you found, what you changed, and what still needs attention

Helpful experience

- Moving older PHP (including PHP 5 or 7) to PHP 8
- MySQL query tuning, migrations, and backups
- Building and debugging C++ on Windows or Linux
- Experience connecting PHP or another web layer to C++ (extensions, command-line tools, or local services)

How to apply

Send a short note with:

- Examples of legacy PHP, MySQL, or C++ systems you have updated
- The languages and tools you use day to day
- Your availability and whether you prefer contract or full-time work
