What I'm looking for

I'm open to full-time on-site positions as well as B2B remote contract roles.

At Testbericht.de, I modernized a legacy PHP 7 platform through its migration to PHP 8 while maintaining production stability. I optimized a database with more than 100 million records and improved average page-load times from approximately 2–3 seconds to around 1 second or less.

I built Elasticsearch-based search infrastructure integrated with Redis caching and WebSocket functionality, and developed data-processing workflows for large volumes of product data. I also investigate production performance issues and review code during ongoing platform improvements.

As a side project, I independently architected and developed HS Concept, an enterprise asset management platform with separate internal, API, and customer-facing services. I built the internal system with CodeIgniter 4, developed a Laravel REST API with JWT authentication, and created the customer platform in React.
