Carlos Mondragón
@carlosmondragn
Front-end developer specialized in React, TypeScript, and responsive UI.
What I'm looking for
I am a front-end developer with strong practical experience building responsive web applications using React, TypeScript, modern JavaScript (ES6+), Tailwind CSS, and Material UI. I prioritize accessibility, component-driven architecture, and consistent styling across devices.
I trained through an intensive, project-based mentorship at CodeCrafters Labs and have full-stack exposure integrating frontends with Node.js/Express backends and exploring Next.js features. I also bring several years of technical support and customer-facing experience working with Microsoft 365, networking, and hardware troubleshooting.
I deliver reliable, maintainable interfaces, collaborate effectively with teams using Git/GitHub workflows, and contribute practical product feedback informed by real-world user support and QA involvement.
