Front-End Developer at RedCore who built animated iGaming promo pages and a responsive falling-coins animation.

Romania

Message

At RedCore, I built responsive iGaming promo pages from Figma designs, with complex CSS animations and cross-browser layouts. I also developed gamification mechanics for casino landing pages.

I built a falling-coins animation for promo pages, with rain, snow, and leaves modes, responsive scaling, and pause behavior when a tab was hidden. I used AI-assisted coding on this work.

Previously, I developed web pages and reusable components at Brain Rocket, and migrated and maintained websites in Adobe Experience Manager at DataArt. I also taught HTML, CSS, and JavaScript basics at IT School Hillel.
