Claudiu: DrupalCon and other community events play a vital role in shaping the direction of the Drupal project. These gatherings foster collaboration between developers, contributors, and businesses, enabling the exchange of ideas and feedback that directly influence core developments. They are also an essential part of keeping the community engaged and fostering new talent.

Since 2008 I’ve attended most of the European DrupalCon editions and one in North-America. But not only global events, such as DrupalCons are important. 

"Local and regional events are crucial because they bring together developers with common needs. This I can tell because, as one of the founders of Drupal Romania Association, I was involved in this kind of events as organizer of several DrupalCamps. Drupal DevDays are also events that I particularly like because they are focused on developers needs."

In terms of trends, there’s a growing focus on decoupled architectures and headless implementations, which allow front-end developers to work with tools like React or Vue.js while leveraging Drupal as a back-end content hub. We’re also seeing increased interest in automated testing, continuous integration, and improving the developer experience.

Another trend is the emphasis on accessibility, both in terms of the admin UI and front-end templates, which is a growing requirement across the globe.

4. As a core subsystem maintainer, you oversee security and design issues within the platform. What are the biggest challenges you face in maintaining the balance between innovation and security for Drupal’s core?

Claudiu: Balancing innovation and security is an ongoing challenge, particularly given Drupal’s large and diverse user base. On one hand, we want to push boundaries with new features and improvements to keep the platform competitive. On the other hand, security is non-negotiable, especially since Drupal is often used by governments and large enterprises with strict security requirements.

"One of the biggest challenges is ensuring that new features do not introduce vulnerabilities. This requires thorough reviews, testing, and sometimes making tough decisions to prioritize stability over fast-paced development. "

It’s crucial to ensure that Drupal’s APIs and modules remain secure by design, which often means working closely with the security team and following best practices from the outset.

5. Drupal has a reputation for being a powerful framework for building complex web applications. How do you ensure that best practices in development are followed while keeping the ecosystem accessible to new developers?

Claudiu: Ensuring best practices is essential to maintaining Drupal’s reputation as a robust framework. The introduction of tools like Composer, automated testing frameworks, and improved developer documentation have all helped in this regard. 
As a maintainer and contributor, I emphasize clean, modular code that follows established coding standards and is well-documented, so it’s easier for others to build upon.

"To keep the ecosystem accessible to new developers, the community has made significant strides in improving the developer experience. Initiatives like "easy out of the box" aim to simplify the onboarding process, reducing the complexity of setting up and working with Drupal."

6. With the rise of technologies like headless CMS, AI, and IoT, how do you see Drupal adapting to integrate these technologies and continue delivering cutting-edge digital experiences?

Claudiu: Drupal is well-positioned to adapt to emerging technologies like headless CMS, AI, and IoT due to its flexibility and API-first architecture. With Drupal’s decoupled capabilities, we’re already seeing it integrated into headless applications where content can be delivered across multiple channels, from websites to mobile apps.

AI and machine learning are also starting to find their place within Drupal, with modules emerging that integrate AI-driven content personalization, chatbots, and search enhancements. 

While these technologies are still maturing, Drupal’s modular nature makes it an ideal platform for experimenting and integrating with third-party AI tools and services. As these trends evolve, Drupal will continue to adapt by leveraging its community to develop solutions that meet modern digital demands.
