§About
Frontend with depth.
Backed by media-scale infrastructure.
I build performant web experiences for Turkish media platforms — HaberTurk, BloombergHT, ShowTV. My work spans custom HTML5 video players, ad-tech integrations, CDN architecture and design systems. I care about craft, defensive code, and shipping things that scale.
