Senem Hartung (the_turk)

I am a senior web developer with an M.S. in Computer Science and 15+ years of experience building and supporting complex websites and custom digital solutions in Drupal. I work across full project lifecycles - from discovery and content modeling to build, launch, and long-term support - with a strong focus on data migration.

I specialize in high-complexity, high-stakes migrations that require careful planning and deep technical skill, including Drupal-to-Drupal projects (major-version upgrades, rebuilds, and restructuring challenging content models) as well as migrations from a wide range of custom CMS platforms into Drupal. I’m comfortable working with inconsistent data, undocumented legacy rules, and tricky edge cases, and I take a methodical approach to ensure content moves safely, accurately, and in a future-ready form.

Beyond migrations, I build custom modules, themes, and integrations, improve performance and maintainability, and collaborate closely with stakeholders to translate goals into reliable implementations. I care about clean architecture, accessibility, and creating sites that are easier to use and support long after launch.
