<about-me/>

Olá, Hola, Hello, I'm Mario Duarte!

I'm a Full Stack Developer with 15+ years of experience, passionate about creating polished solutions across the full development lifecycle, from UI and UX design to development and delivery, bridging the gap between intricate engineering and exceptional user experience.

As a Senior Frontend Engineer at Tillit Invest, I am currently leveraging my expertise in React, Next.js, and TypeScript to build a next-generation DIY investment platform. My deep understanding of both development and design—using tools like Figma and Sketch—allows me to translate complex requirements into intuitive and visually appealing interfaces.

My technical foundation includes a mastery of the modern web stack, backend development with Node.js and PHP, and database management with GraphQL and MongoDB. I am highly proficient in managing CI/CD pipelines and deploying to platforms like Vercel, AWS, and Netlify.

I'm always eager to tackle new challenges, collaborate with fantastic teams, and make a positive impact through my work. If you're interested in connecting or discussing exciting opportunities, feel free to reach out! Let's create something amazing together!
