Principal Engineer & Technical Customer Success Manager — İzmir, Türkiye. 15 years building and shipping frontend platforms, build pipelines, and release tooling.
Currently building — Frezpo
Frezpo turns one client brief into a matched Google Ads + landing page strategy pack — ad architecture, landing page strategy, and design tokens generated together, so the ad's promise and the page's headline never drift apart.
The problem it targets is message match: the gap between what an ad promises and what the landing page delivers. High click-through with a high bounce rate is almost always this gap, and it opens because the ads and the page get written by different people, at different times, from different briefs.
