Testimonials

What Our Clients Say

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.

Frank W.

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.

Dinant V.

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.

Timur G.

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.

Musa S.

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.

Taj S.

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

Frequently Asked Questions

Premium themes are built for the broadest possible audience - they ship with hundreds of features you will never use, bloated stylesheets, and JavaScript that loads on every page. A custom WordPress developer builds exactly what your site needs, nothing more. The result is a faster, more maintainable site that you own entirely and can extend without fighting someone else's framework.

Standard placement is 48 hours from contract signing. WordPress is one of our deepest talent pools. For developers with specific expertise - headless WP, WooCommerce subscriptions, or multisite enterprise setups - 48 to 72 hours is typical.

We can work with page builder sites if that is the existing setup and migration is not in scope. For new projects, we build with Gutenberg and the native WordPress block editor - it is faster, produces cleaner markup, and does not create a dependency on a third-party plugin for the site to function. Elementor and Divi make every page and update slower; we prefer not to recommend them for production sites.

Yes. Custom block development is a core competency. We build static and dynamic (server-rendered) blocks using the Block Editor API and React, configure InnerBlocks for flexible content regions, implement block styles and transforms, and follow WordPress coding standards so blocks are update-safe and work correctly across the full site editor.

We apply WordPress security best practices across every engagement: input validation and output escaping at every data boundary, nonce verification for all form submissions, capability checks before any sensitive operation, parameterised database queries, minimal plugin footprint, and automatic updates for security releases. We never rely on obscurity - we implement defence in depth.

Yes. WooCommerce is highly extensible via action and filter hooks, and our developers know the hook map well. We add custom product types, modify checkout fields, integrate payment gateways, build order fulfilment workflows, add custom shipping methods, and create admin reporting extensions - all without modifying WooCommerce core files so updates remain safe.

Headless WordPress separates the CMS (where editors create content) from the frontend (where users experience it). Content editors continue to use the familiar WordPress interface, while the frontend is built with a modern framework like Next.js - delivering far better performance, developer experience, and design flexibility. It is the right choice when performance is critical, the design requires more than WordPress themes can deliver, or the frontend is shared across web and mobile.

Yes. We migrate content from other CMS platforms - Webflow, Squarespace, Shopify Blog, Drupal, and custom codebases - to WordPress. Migrations include content import, URL structure preservation with proper 301 redirects, media file transfer, SEO metadata mapping, and validation against the original site before the DNS cutover.

Yes. WordPress performance optimisation is a distinct engagement type we offer. We audit the plugin stack to remove unnecessary JavaScript, configure object caching with Redis via WP Object Cache, implement page caching, optimise database queries with query monitor, set appropriate image sizes, and configure a CDN. The goal is consistent 90+ Lighthouse scores on all key pages.

We set up staging environments for testing updates before they hit production, configure automated core and plugin security updates, and implement a structured update workflow with testing and rollback capability. For ongoing maintenance retainers, we handle monthly update cycles, uptime monitoring, and emergency response.

The minimum engagement is one month. WordPress projects range from focused theme builds (six to eight weeks) to multi-year product partnerships covering new features, maintenance, and platform evolution. Most clients continue as ongoing retainer clients after the initial build.

Fixed-price project engagements are available for well-scoped deliverables - a custom theme, a plugin, a WooCommerce extension. Monthly retainer and time-and-materials models are available for ongoing development and maintenance. All models include a dedicated account manager and transparent reporting.
