Drupal Development
For over 13 years I have specialized in freelance Drupal development for Czech and international clients. I build custom modules, integrate external systems, perform security audits, and lead demanding upgrades from Drupal 7 to the latest releases. Whether you need a new corporate portal, want to extend an existing site, or stabilize a critical application, I build solutions that scale and are maintainable over time.
Custom Drupal Module Development
Every project has specific rules. Instead of compromising with contrib modules, I write custom solutions tailored to your workflow—from custom entities, forms, and validation to integrations with external APIs. I focus on clean architecture, dependency injection, testability, and secure input handling.
Content Migrations
I move data from legacy editorial systems, other CMSs, or external sources into Drupal using ETL pipelines and the Drupal Migration API. I ensure consistent mapping of fields, URL aliases, users, taxonomies, and media files.
Drupal 7 → 11 Upgrades
I do not discard older sites. I perform safe upgrades from Drupal 7, 8, and 9 to Drupal 10/11, including auditing used modules, replacing deprecated dependencies, refactoring custom code, and preparing production deployments.
API Integrations and Headless
I design REST and JSON:API layers for headless and hybrid applications. I connect Drupal with CRM, ERP, e-commerce, payment gateways, RAG knowledge bases, or AI services.
Audits, Refactoring, and Security
I review custom module and theme code for XSS, SQL injection, CSRF, and access-control gaps. I improve performance, maintainability, and prepare sites for security updates.
Operations and DevOps
I deploy to Docker, VPS, and AWS. I automate CI/CD pipelines in GitLab, manage DDEV development environments, and ensure monitoring, backups, and regular maintenance.
Selected Work
Drupal projects include:
- Photostock browser integration – custom Drupal module imago
- AI helpers for content management – editorial SEO and translation automation
- Price monitoring and PPC automation – connecting e-commerce data with advertising
How We Work Together
- Initial consultation – we discuss goals, current state, and technical constraints.
- Analysis and proposal – I prepare architecture, scope estimate, and timeline.
- Development – iterations with regular demos, code review, and automated tests.
- Deployment – CI/CD pipeline, production environment preparation, and monitoring.
- Maintenance and evolution – updates, security patches, and new features as needed.
I can work directly with your team or operate as an external specialist. Transparency, clean code, and long-term maintainability are important to me.
