💻 PHP 8.2/8.3 · Symfony · Doctrine · Legacy Modernisation

I’m working with a well-established UK technology business looking for an experienced PHP / Symfony Contractor to join an urgent 6-month platform upgrade.

This isn’t a greenfield build, and they’re not looking for a generalist PHP developer.

They specifically need someone who has successfully delivered large-scale upgrades of legacy PHP/Symfony applications before and can come in, understand an established codebase and start contributing quickly.

You’ll be working on a substantial legacy platform, helping modernise the PHP and Symfony stack while navigating the dependencies, technical debt and migration challenges that come with upgrading a mature production system.

Could be a strong fit if you:

• Have strong commercial PHP experience, ideally including PHP 8.2 / 8.3

• Have deep production experience with Symfony

• Have personally delivered major Symfony framework upgrades or migrations

• Are comfortable working within large, established legacy codebases

• Have strong experience with Doctrine

• Understand the challenges around dependencies, backwards compatibility, testing and incremental modernisation

• Can operate independently and deliver from day one in a contract environment

• Ideally have completed multiple previous upgrade or migration contracts

Experience with Twig and Mockery would also be beneficial.

The key requirement here is specific legacy upgrade experience .
