I'm an experienced UI/UX designer focused on creating high converting landing pages, websites, web apps and mobile apps. I'm also an accomplished Logo/branding designer. My favorite design tool is Figma. I also can turn my designs into Wordpress (Elementor pro), Webflow, Framer or into clean, fast loading, responsive HTML/CSS. I’m a human designer who knows how to use AI tools to enhance design, copywriting, prototyping, and imagery when needed, so Lovable, Claude, Cursor, and similar tools are part of my stack when appropriate — always guided by real UI/UX and product design experience. I'm always online, weekends too, if you have a questions don't hesitate to contact me. I’m not part of any agency, and I don’t represent someone else’s work.
