PHP Development Services Our Developers Provide
Hire dedicated PHP developers for complete web and backend engineering from custom application development and enterprise frameworks to APIs, SaaS, eCommerce, modernization, performance, and production support.
Custom PHP Web Application Development
We build purpose-built PHP applications around your workflows, users, integrations, and business rules. Our developers create business applications, customer portals, administration systems, workflow platforms, booking systems, marketplaces, dashboards, and data-driven products. We use an appropriate PHP framework or custom architecture based on project requirements rather than adding unnecessary framework complexity.
Enterprise PHP Application Development
Our team develops enterprise solutions focused on maintainability, security, integration, access management, testing, and scalability. Functionality may include enterprise-level authentication, access controls, workflow management, rule engines, reporting, auditing, APIs, integration, and background processing functionality. We design production environments based on availability requirements, such as 99.9% uptime, provided the infrastructure allows it.
PHP Backend Development
We develop backend services for web applications, mobile applications, SaaS platforms, and enterprise applications. Our backend services can range from business logic to authentication/authorization, databases, APIs, file processing, queues, caching, notifications, and third-party integrations.
Laravel Development
For projects that benefit from Laravel's efficiency, queue handling, ORM, testing tools, and coding conventions, our engineers develop new PHP-based applications using Laravel. Capabilities may include Laravel apps, RESTful APIs, Eloquent ORM, queues, events, notifications, and authentication. We have extensive experience with Laravel Sanctum, Laravel Passport, Laravel Horizon, Scout, Scheduler, and Octane for performance-critical needs. For new Laravel projects, we use currently supported versions of the framework, not older versions.
Symfony Development
We build structured and long-lived enterprise applications using Symfony and its reusable components. Suitable applications include enterprise portals, SaaS products, complex APIs, business platforms, integration systems, and large modular applications. Our developers can support both current Symfony releases and LTS environments depending on your maintenance strategy.
PHP API Development & Integration
Our developers help you build secure APIs to link applications, mobile apps, enterprise software, and other third-party services. We have experience with REST, GraphQL, OpenAPI, webhooks, OAuth 2.0, OpenID Connect, JWT, and SOAP when needed. For example, the existing CMARIX expertise in PHP offers up to 40% improved data transfer speed through proper optimization of APIs. Actual speed gains depend on factors such as current APIs, databases, network, caching, and more.
PHP SaaS Application Development
We offer subscription-based and multi-user SaaS applications that fit into your business model. Features include user accounts, organizations, multi-tenancy, permissions, subscription flows, billing, usage, reporting, dashboards, notifications, API integration, and administration.

We develop, customize, integrate, and support content platforms using PHP. This includes work on WordPress, Drupal, custom Laravel CMS platforms, and other suitable existing PHP content platforms. Possible features include custom modules, plugins, themes, APIs, editing workflows, permissions, search, and multilingual content management.
PHP eCommerce Development
Our developers build and customize commerce applications on PHP-based platforms and frameworks. We develop applications for Magento/Adobe Commerce, WooCommerce, customized Laravel commerce, and marketplaces. It involves payment integration, shipping, stock management, order processing, and customer account management. In our view, the choice of commerce platform depends on business complexity, not the other way around.
PHP Microservices & Modular Architecture
Build services that can be deployed independently when underlying technical and organizational needs call for a distributed system. Capabilities can range from REST and messaging to RabbitMQ, Kafka, Redis, Docker, Kubernetes, service authentication, and observability. Not all microservices are better than a monolithic application, especially a modular one.

Our team develops and deploys PHP-based applications for AWS, Microsoft Azure, Google Cloud, DigitalOcean, and Cloudflare-based infrastructures. Functionality may include computing, database management systems, object storage, CDN, queuing, caching, load balancing, auto-scaling, and monitoring. Choose the cloud architecture based on workload requirements, not service availability.
PHP Queue & Asynchronous Processing
We move expensive or non-blocking application tasks out of synchronous HTTP requests to optimize response times. Use cases include email, notifications, imports, exports, image processing, video processing, webhooks, report generation, and third-party synchronization. Technologies can include Redis, RabbitMQ, AWS SQS, Laravel Queues, and Symfony Messenger.
AI Integration with PHP Applications
We integrate using server-side APIs that provide secure access to AI capabilities for our PHP-based solutions. Use cases may include AI assistants, document understanding, semantic search, content workflow automation, recommendations, classification, business process automation, and RAG. The following solutions can integrate with our PHP-based offerings: OpenAI, Azure OpenAI, Google AI Services, Anthropic, and custom models.
PHP Performance, Security & Maintenance
Our team keeps business-critical PHP applications secure, supported, and performant.
