Symfony Development

Custom Symfony development for complex business applications: modular architecture, API Platform, Doctrine, legacy modernization.

Symfony architecture illustration — domain modules, API and message bus

Symfony is our choice when a project needs enterprise-grade structure: strict architecture, a predictable upgrade path and components that integrate cleanly with the wider PHP ecosystem. We reach for it for complex backends, API-first applications and domains too rich for a lighter framework.

Where Symfony fits best

  • API-first backends — API Platform or hand-built REST/GraphQL endpoints with explicit serialization and versioning.
  • Complex business systems — invoicing, logistics, multi-organization platforms — where Symfony's Form, Validator and Workflow components earn their keep.
  • Long-lived codebases where Symfony's LTS releases and BC promise matter more than the newest features.
  • Standalone components — Console, HttpClient, Messenger and EventDispatcher work well inside non-Symfony projects too.

What a request looks like

Symfony request lifecycle with Messenger async transport

Everything is explicit: routing, validation and serialization are framework concerns; the handler holds the domain logic. Async work goes through Messenger to a Doctrine or RabbitMQ transport.

How we structure the code

Applications are organized around the domain, not the framework: thin controllers, explicit services, honest Doctrine entities, business logic testable without booting the kernel.

#[AsMessageHandler]
final class GenerateInvoiceHandler
{
    public function __construct(
        private InvoiceRepository $invoices,
        private PdfRenderer $pdf,
    ) {}

    public function __invoke(GenerateInvoice $command): void
    {
        $invoice = $this->invoices->get($command->invoiceId);
        $this->pdf->render($invoice);
        $invoice->markGenerated();
    }
}

Migration and modernization

For legacy PHP — Zend, Symfony 2/3/4 or framework-less code — we migrate incrementally: old and new run side by side, modules move one at a time, and the business keeps running. Share your requirements and we'll tell you honestly whether Symfony, Laravel or something else fits better.
