Mário Monteiro

I've designed high-converting SMS popups and email experiences for Postscript's eCommerce platform, supporting brands including Feastables, HexClad, and InnoSupps. I combine CRO, responsive design, and brand guidelines to improve engagement across devices.

I've led end-to-end SaaS design and frontend delivery at Viansari and maintained and restructured Monocard's e-commerce platform using React.js, Next.js, TypeScript, Chakra UI, and WordPress. My work focuses on scalable codebases, performance, visual consistency, and user experience.

Across freelance projects, I've designed medical appointment, music streaming, betting SaaS, and portfolio products from research and wireframes through implementation. I use Figma, Adobe XD, HTML, CSS, JavaScript, React Native, Node.js, and PostgreSQL to turn user needs into functional digital products.

I enjoy collaborating with clients, developers, marketers, and content creators, while documenting work and mentoring teams to improve delivery quality. I bring more than five years of frontend, UI/UX, and conversion optimization experience to clean, user-friendly digital experiences.
