🔗 About Me

Hi, I'm here to work on our next project.

I'm a passionate full-stack developer, trained in practical bootcamps like freeCodeCamp, where I built a solid foundation in web development, JavaScript, React, and backend technologies. With over 2 years of continuous learning and hands-on practice, I've built real-world solutions ranging from junior-level applications to more complex semi-senior systems.

I've developed a variety of web projects, including my responsive portfolios, landing pages, dynamic CRUD systems, and dashboard interfaces. My work focuses on clean architecture, efficient state management, and performance optimization.

My technical background includes self-paced certifications, project-based learning, continuous skill enhancement through modern documentation, and upcoming open source contributions.
