§ 05—ABOUT / THE SHORT VERSION

9 years.One platform.Zero pivots.

I'm Cengiz — a Shopify developer based in Izmir, Turkey, who's been inside the Liquid engine since 2017. I don't do WordPress, I don't do “full-stack,” and I don't do vague estimates.

Everything I ship lives inside Shopify's borders. That's the whole pitch. Specialization is a feature, not a limitation.
