Portfolio Vivaldo

Hi! My name is Vivaldo Santana, I'm a Web Developer based in Ottawa, Canada, with a strong passion for technology and innovation. I graduated in Web Development and Internet Applications from Algonquin College, where I developed skills in building responsive websites and designing intuitive user interfaces.

I have hands-on experience with HTML, CSS, JavaScript, and PHP, and have worked on several projects focused on responsive design and UI/UX best practices.

Recently, I’ve developed a strong interest in cloud computing. I completed a course on Amazon Web Services (AWS) and have been working on personal projects to deepen my understanding of cloud infrastructure and deployment. I'm transitioning into cloud computing and seeking an entry-level opportunity where I can contribute from day one while continuing to develop my skills.

I'm naturally curious and constantly learning. Whether it’s front-end development or cloud architecture, I strive to build digital solutions that are efficient, accessible, and impactful.

Feel free to connect with me on LinkedIn or reach out via email or whatsapp. I’m always open to discussing new projects, ideas, or opportunities in the tech space.
