Description

Are you looking to build a scalable Enterprise platform or modernize a complex legacy system?

I help businesses solve architectural challenges that standard developers often cannot handle. With 17+ years of experience, I bring a level of stability and foresight to your project that ensures long-term success, not just a quick fix.

I provide end-to-end architectural leadership. Whether you need to migrate sensitive data, integrate complex third-party tools, or build a high-performance backend, I guide you through the full software lifecycle—bridging the gap between legacy systems and modern, decoupled architectures.

Here is how I add value to your project:

Scalable Architecture & Performance

I ensure your platform can grow with your business. I design robust database schemas and implement advanced caching strategies (Varnish, Redis) to handle high traffic. I have architected solutions spanning Drupal 6 to 11, ensuring your code remains maintainable for years.

Advanced Backend Engineering

When off-the-shelf plugins aren't enough, I build custom solutions. I develop bespoke modules to handle your unique business logic, utilizing deep expertise in Drupal APIs (Entity, Form, Batch) and object-oriented PHP to create secure, efficient software.

Seamless Ecosystem Integration

I make your tools talk to each other. I engineer middleware to synchronize Drupal with your external ecosystem—including CRMs (Salesforce, HubSpot), ERPs, and Payment Gateways. I also implement RESTful and JSON:API web services for modern Headless applications.

Secure Data Migration

I take the risk out of upgrades. I lead critical migration projects, moving your legacy data from non-standard SQL structures or older CMS versions into modern Drupal entities with zero data loss.

Frontend & Theming

I deliver polished user experiences. I create pixel-perfect, accessible (WCAG) themes using Twig, translating your complex design systems into responsive, user-friendly interfaces.
