About Me

Professional Summary

UI Developer with over 15 years of experience in front-end and web development, specializing in turning Figma/XD designs into responsive, pixel-perfect, and cross-browser-compatible interfaces using HTML5 and CSS3. Proficient in building reusable UI components in JavaScript, React.js, and Next.js, often preparing component structures and UI layouts for handover to the JavaScript team for further functionality and integration.

Not a UI/UX Designer — My primary role is front-end implementation, not visual design creation.

Proven leadership in guiding UI/CSS teams and delivering scalable, CMS-driven websites and platforms — including major fantasy gaming systems and high-traffic sports media projects. Currently working as a contractual UI Developer at Sportz Interactive, focusing on modular and scalable in-house platform development.
