Summary
👤
Senior🎓
Top SchoolSelim Şumlu is a digital entrepreneur, localization lead and former tech editor with 14+ years turning technology content into accessible experiences for Turkish audiences. As founder and "Chief Dreamer" of Hayalet he combines web publishing, design and software localization with a background as executive editor of PCnet, where he grew its online presence from his teens into one of Turkey’s largest tech sites. A long-time Mozilla contributor and Turkish localization manager, he has helped bring projects like Firefox Monitor, Send, Screenshots and Common Voice to Turkish users, blending editorial rigor with internationalization expertise. His work spans magazines, apps and major web platforms, and he volunteers on high-impact open-source localization projects—an editor’s attention to nuance that informs both product copy and technical translations. Unusual for a technologist, he’s also a prolific translator of popular science, song lyrics and subtitles, reflecting a deep commitment to clear, culturally attuned communication.
