EXPERTISE
WHAT WE DO
We build full-featured Laravel applications, Eloquent models, service containers, queued jobs, event broadcasting, Sanctum API authentication, and Horizon for queue monitoring.
We design and build RESTful APIs with Laravel or Slim, versioning, authentication, validation, pagination, rate limiting, and OpenAPI documentation consumed by frontend or mobile clients.
We build and extend WooCommerce and custom PHP e-commerce solutions, product catalogues, checkout flows, payment gateway integrations (Stripe, Braintree), and order management systems.
We assess legacy PHP codebases, migrate from procedural to object-oriented architecture, introduce testing, upgrade to PHP 8.x, and refactor towards Laravel or Symfony frameworks incrementally.
We integrate PHP applications with CRMs, ERPs, payment processors, shipping APIs, and marketing platforms, building robust wrappers with retry logic, error handling, and webhook verification.
We profile PHP applications with Blackfire or Xdebug, eliminate N+1 queries in Eloquent, configure OPcache and Redis query caching, and optimise database indexes to reduce page generation time.

CASE STUDIES
Testimonials
What impressed us most was how Kultrix handled the full stack - frontend, backend, and mobile - with one cohesive team. Communication was clear, delivery was predictable, and the final product exceeded what we initially scoped.
Co-CEO
Kultrix built both our web platform and mobile app from scratch. Their team understood the complexity of our industrial workflows and translated them into clean, intuitive interfaces. We launched on time and our operators adopted the tools immediately.
Co-CEO
Kultrix handled everything for us - landing page, dashboard, mobile app, and even a Chrome extension. Having one team own the entire product surface meant everything felt connected and consistent. They shipped fast and the quality speaks for itself.
CEO, Ping Proxies
Kultrix has been our go-to partner for multiple projects - from marketing websites to full mobile applications and backend systems. They scale up when we need speed and maintain consistency across every project. Reliable, fast, and technically strong.
CEO, Volume Apps
Working with Kultrix on our mobile app and backend was seamless. They brought strong product thinking to every sprint, not just code. When priorities shifted, they adapted quickly without losing momentum. Exactly the kind of partner a product team needs.
Product Lead, Pelago
We needed a team that could handle mobile development, server infrastructure, and AI features all at once. Kultrix delivered on all three fronts. Our fitness platform went from concept to production in under four months with zero compromises on quality.

FAQ
PHP 8.x is a modern, well-maintained language with strong type support, fibers for async, JIT compilation, and a vibrant ecosystem led by Laravel. For web applications - particularly content-heavy platforms, e-commerce, and API backends - PHP with Laravel remains highly productive and cost-effective. Kultrix uses PHP where it is the right technical and business fit, not out of habit.
Standard placement is 48 hours from contract signing. PHP is one of our largest talent pools. For developers with specific framework expertise - Symfony, Magento, or headless CMS integrations - 48 to 72 hours is typical.
Both - the choice depends on the project type. Laravel is our default for most web applications because of its developer-friendly API, rich first-party packages (Cashier for billing, Sanctum for auth, Horizon for queues), and fast onboarding. Symfony is preferred for large enterprise applications where strict standards, component independence, and long-term maintenance matter more than development speed.
Yes. Custom WordPress theme and plugin development is a distinct competency for our PHP team. This includes custom post types, taxonomy queries, Gutenberg block development with React, WooCommerce extensions, and REST API customisations. For complex projects, we also work with headless WordPress using WPGraphQL and a Next.js frontend.
Security is built in, not bolted on. Our developers use parameterised queries or Eloquent to prevent SQL injection, validate all inputs at the request layer, escape all output, set strict Content Security Policy headers, use Laravel's CSRF protection, implement proper session management, and follow OWASP Top 10 guidance. Security review is part of every pull request.
Yes - legacy PHP modernisation is one of our most common engagements. We start with a thorough audit of the codebase, document the technical debt, and produce a phased migration plan. We introduce testing first (to create a safety net), then migrate incrementally - avoiding the risk of a big-bang rewrite that takes months and breaks production.
MySQL and MariaDB are the most common relational databases in PHP ecosystems, and our developers have deep experience with both. We also work with PostgreSQL when the project requires advanced features like JSONB, window functions, or full-text search. Redis is our standard for caching and session storage.
Yes. We write unit tests with PHPUnit and feature tests using Laravel's built-in HTTP testing layer against a real database (using transactions for rollback between tests). For complex business logic, we apply test-driven development. Coverage targets are agreed at project start and enforced in the CI pipeline.
Yes. We build headless WordPress and Strapi setups with PHP backend APIs consumed by Next.js or Nuxt frontends. We configure WPGraphQL or the WordPress REST API with custom post type schemas, handle authentication for preview drafts, and implement webhook-triggered static regeneration so content updates propagate to the frontend within seconds.
We configure Laravel Forge, Deployer, or GitHub Actions for automated deployment - zero-downtime releases with atomic symlink swaps, environment variable management, artisan command execution, and queue worker restarts. For containerised PHP, we write optimised Docker images with PHP-FPM and Nginx, deployed to Railway, AWS ECS, or your preferred cloud.
The minimum engagement is one month. PHP projects range from short-term feature sprints to multi-year product partnerships. Most clients continue beyond the initial term once they experience the quality and communication standards Kultrix maintains.
Monthly retainer and time-and-materials models are both available. Retainer engagements provide a fixed monthly developer allocation with guaranteed availability. T&M engagements are billed weekly against tracked hours. Both models include a dedicated account manager, transparent timesheets, and weekly progress reports.
