At Guide to Iceland, I worked on a high-load travel platform with a mix of legacy and modern backend components. I developed and maintained REST, GraphQL, and SOAP APIs, integrated external services and payment systems, and improved performance through caching and search-oriented optimizations.

Across projects including Rakuten Photo Studio, Intao, and Convencium, I designed and implemented backend services with PHP frameworks including Laravel and Zend Framework. My work has included PostgreSQL database architecture, search integrations, and modernizing existing systems while preserving production stability.
