Technologies / Drupal
We build, migrate, and maintain Drupal sites for enterprise teams. Multi-site, security-hardened, GDPR-ready.

OUR SERVICES
We’ve shipped Drupal inside multi-country CMS rebuilds, with security hardening, penetration testing, and integrations to ten different claim-handling systems. If you’re migrating from Drupal 7, consolidating sites, or building something new, we’ve done the work at enterprise scale.
We build Drupal sites from scratch when off-the-shelf modules won’t cover the content model, the admin workflow, or the integrations a project actually needs. One healthcare client (under NDA) needed an admin panel that let non-technical staff manage patient stories, medical resources, and clinical content from one place. We built it, designed the front-end themes, and shipped a platform their team runs without developer help.
Custom modules where Drupal’s contributed modules fall short, or where a contributed module slows the site down at scale. We use REST APIs and Redis caching to build features that hold up at millions of page views per month. If a contributed module already does the job well, we use it. If it doesn’t, we write what’s needed.
Drupal 7 to 10 migrations, system integrations with SAP, payment providers, claim-handling platforms, and custom APIs. We’ve moved enterprise clients off legacy Drupal stacks without breaking their content, URLs, or search rankings. If the right answer is to migrate off Drupal entirely, we say so before the project starts.
BENEFITS
What we build inside Drupal: custom modules, hook implementations, entity types, and API layers. We use REST, JSON:API, and GraphQL depending on what the frontend needs.
Custom themes built on Twig, with Sass for styling and React, Angular, or Vue when the project needs a decoupled or hybrid frontend.
Database schemas designed for the content model, caching at the application and CDN layer, and profiling with Blackfire or Xdebug when something’s slow.
Composer for dependencies, Drush for site management, Docker for environment parity, Git for version control, and CI/CD pipelines for deploys.

No discovery decks, no SDR call, no scripted pitch. Just a conversation about what you’re trying to build and whether we’re the right people to build it. Get in touch and let’s figure it out.
FAQ
Drupal makes sense when you need complex content models, multi-site setups, granular user permissions, or strict security requirements. WordPress is faster and cheaper for content marketing sites. Headless CMSs like Strapi or Contentful fit teams building app-like frontends with React or Next.js. We help clients pick the right one, not default to Drupal.
Yes. Drupal runs government sites, banks, universities, and multi-country corporate sites because it handles strict security, multi-site governance, complex permissions, and integrations the way enterprises actually need. We’ve shipped Drupal inside a multi-country financial services rebuild alongside WordPress, Magento, Laravel, and Next.js, with security hardening and penetration testing.
Drupal handles multi-site and multi-language natively. One codebase can run dozens of sites with shared modules, separate content, and country-specific configuration. Translation workflows are built in. We’ve used this on enterprise rebuilds covering multiple countries, each with its own content, language, regulations, and integrations.
Drupal 7 reached end-of-life in January 2025. Migration to Drupal 10 needs a full content audit, module compatibility check, custom code rewrites, and a content migration plan. We assess whether upgrading, rebuilding on Drupal 10, or moving to a different stack is the better call, then ship it without breaking URLs, content, or SEO.
A clean migration preserves URLs with redirects, keeps metadata and structured data intact, and maintains crawl depth so Google doesn’t drop rankings. We map every legacy URL to its new destination before launch, run a staging crawl against production, and monitor traffic for the first 30 days post-launch to catch issues early.
Drupal works well as a headless CMS. The frontend can be React, Next.js, Vue, or any framework that consumes JSON:API or GraphQL, while editors keep Drupal’s familiar admin interface. This works when you want editorial flexibility on the backend and a modern app-like experience on the frontend.
Yes. Drupal exposes REST, JSON:API, and GraphQL endpoints, and we’ve built custom integrations with SAP, ERP platforms, PIM systems, payment providers, and claim-handling platforms. The financial services group we work with runs Drupal alongside integrations to multiple claim types and payment providers.
Two weeks is typical from signed contract to a developer in your standup. Faster if we already have someone matched. Slower if your project needs a specific industry background or security clearance.
We don’t bench-warm developers, so we won’t promise next week. We’ll give you a real date based on who’s available and what you need.
Yes. We offer three engagement models: staff augmentation for extending your team, dedicated teams for ongoing work, and full project ownership when you want us to handle
delivery end to end.
Part-time arrangements work for staff augmentation. For dedicated teams and full projects, we recommend full-time allocation because context-switching kills productivity on complex codebases.
During the project, you work directly with the developers building your software. No account managers between you and the code. Weekly demos, shared sprint boards, and direct Slack access.
After launch, we offer maintenance, bug fixes, and feature additions under a separate support agreement. If you’d rather take it in-house, we hand over clean documentation and the full repository. Your code, your repo, from day one.
Yes. For staff augmentation and dedicated teams, you interview candidates the same way you’d interview an in-house hire. Technical screens, pair programming, culture fit, whatever your process requires.
Clients about us
We needed a tech partner who could help us scale Greenfee365 into the global marketplace, and Zendev exceeded our expectations.
Their team developed custom solutions that optimized our booking platform, resulting in faster load times and an improved user experience
Zendev understood our vision of connecting women with the right therapists. They improved the platform, were easy to collaborate with, and meeting them in person built real trust.
The PDT app was our first big step into the digital world using apps and Cloud solutions. By implementing this app, we could, with one tool, solve multiple issues that we had with our delivery process of new machines to our customers. The app helps us improve the machine quality, shorten our lead time and increase our cash flow.
Zendev really transformed our entire tech situation in the company. We had this big backend system that was overwhelming us, but now it’s running beautifully.
From the beginning, the Zendev team has immersed themselves in our needs, goals, and long-term visions. We’ve been assigned a dedicated point of contact for our digital marketing and development needs at ZenDev.
Pleased with their commitment and going the extra mile, we now consider them a part of our internal team and value their work, which has evolved into a friendship.
Given a very tight timeframe, we are satisfied with having a user-friendly app that we now hope to further develop and refine.
We are pleased with the collaboration with Zendev and our contact person Aida, who has been very available, helpful, and quick. Thank you!
