PHPSERVER-SIDESOLID

PHP remains the backbone of many commerce and CMS stacks. We modernise codebases, optimise Shopware extensions and build stable integration layers.

We arePHPengineers

We work to strict standards: dependency injection, the test pyramid and clear layers instead of script soup.

  • Shopware 6 PHP extensions and domain logic
  • REST/SOAP integrations, queues and background jobs
  • Composer, static analysis and CI quality gates
  • Performance, OPcache and profiled hot paths
Image about: We are PHP engineers

Mature runtime & ecosystem

PHP 8.x with JIT and types accelerates real production workloads; Composer manages dependencies reproducibly.

Frameworks & CMS integration

Shopware, Symfony components and established patterns enable structured extensions instead of copy-paste.

Scaling & horizontal growth

Stateless app servers, caching and queue workers distribute load – PHP stays the orchestrating core.

Security & hardening

Input validation, CSRF, secure sessions and dependency updates are part of our standard recipe.

Services &solutions

We take on extension engineering, reviews and operations – or guide migrations with a clear risk assessment.

  • Shopware plugins, custom entities and events
  • APIs for PIM, ERP, payment and fulfillment
  • Legacy modernisation and technical debt reduction
  • Observability: logs, metrics, alarms and runbooks

Commerce rules & price logic

Rule builders and individual conditions need clean domain models – PHP modules encapsulate business logic in a testable way.

Heavy interface load

High-volume imports and exports need batch strategies, idempotent jobs and retry-safe workers.

Frequently asked questions about PHP

When is PHP the right choice for our project?
PHP remains the backbone of many commerce and CMS stacks and makes the most sense when you build on Shopware 6, Symfony or an existing PHP codebase. We recommend it wherever server-side business logic, shop extensions and stable integration layers are at the centre of the work. For purely data-driven AI pipelines or real-time event backends, we often deliberately reach for Python or Node.js instead.
How exactly do you approach development with PHP?
We work to strict standards instead of script soup: dependency injection, clear layers and a well-considered test pyramid. Composer-based dependency management, static analysis and CI quality gates are part of our setup from day one. That keeps your backend maintainable and traceable even as complexity grows.
How do you connect PHP to our existing systems?
We build integration layers via REST and SOAP connections and decouple long-running tasks with queues and background jobs. This lets us cleanly link Shopware or your existing backend to PIM, ERP, payment and fulfillment. We deliberately encapsulate interfaces so third-party systems don't bleed into your domain logic and changes stay local.
Can you modernise an older PHP codebase instead of rebuilding it?
Yes, legacy modernisation and technical-debt reduction are a core part of our work. We refactor step by step into clear layers, add tests as we go and secure releases with static analysis and CI, rather than tearing everything down at once. A full rebuild only makes sense when the architecture fundamentally no longer holds up.
How do you ensure performance and stable operation?
We profile the critical code paths deliberately and use OPcache along with fitting caching strategies instead of optimising blindly. For operations we rely on observability with logs, metrics, alarms and runbooks so issues surface early. That keeps your PHP backend predictable under load and safe to deploy.
