Currently building

Frezpo turns one client brief into a matched Google Ads and 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 that gap, and it opens because the ads and the page get written by different people, at different times, from different briefs.

Selected work

• Akbank — refactored a hybrid React Native project into a standalone AAR package: build times 50 min → 10 min, an 80% reduction, removing the Java team's Node.js dependency.
• eBay — cut first render on a high-traffic commerce platform from 1.5 s to 600 ms by attacking virtual-DOM CPU load in SSR and moving the critical path to Node.js/EJS.
• Appcircle — built AI-integrated reporting over Jenkins and internal APIs, driving weekly bug tickets from 26 down to 8 through feature/bug ratio analysis.
• Microsoft & Innovance — standardised React and React Native build and release strategy on Azure across 15 development teams, through UAT and production.
