Yurii Panchenko

Professional Summary

I am a Senior Software Engineer and Platform Architect with over 25 years of experience in software development, including more than 10 years specializing in enterprise PHP applications, TYPO3 CMS, backend engineering, and platform architecture.

My expertise combines enterprise CMS development, custom PHP solutions, REST API integrations, Docker-based infrastructure, Linux server administration, GitLab CI/CD automation, and AI-powered business workflows.

Throughout my career, I have participated in the development, modernization, and technical support of more than 40 TYPO3-based projects, including enterprise websites, publishing platforms, e-commerce solutions, access management systems, and complex business applications.

I specialize in designing scalable, maintainable, and secure software architectures. My approach focuses on reusable components, clean code, performance optimization, automation, and long-term system reliability.

In addition to backend development, I have extensive hands-on experience with DevOps engineering, including containerized environments, automated deployment pipelines, production infrastructure, and server optimization.

I also work with AI integration and workflow automation, helping businesses incorporate artificial intelligence into existing platforms, automate content processing, integrate external services, and improve operational efficiency.

My primary CMS expertise is TYPO3, covering versions 7 through 14. However, my strong PHP backend development background and enterprise CMS architecture experience also allow me to work with other PHP-based platforms and adapt to technologies such as Drupal.

Since 2017, I have worked remotely with international clients, delivering enterprise software solutions and providing long-term technical support.

I am available for remote cooperation worldwide and open to relocation for suitable long-term opportunities.
