WILLIAM MANCHABAJOY

Digital Marketing Analyst

Bogotá

7th-semester Software Engineering student and Front-End Developer with a non-traditional background in B2B digital marketing. While I have a solid base in HTML, CSS, JavaScript, and React.js, my biggest strength is using AI tools like Gemini, ChatGPT, and Claude to learn fast, solve complex problems, and build practical solutions. Thanks to my marketing experience working with US clients, I understand how a business works beyond just the code. I bring strong communication skills, empathy, and a genuine passion for continuous learning to the team.
