About Me

Hello! I'm Waweru, a passionate full-stack developer with over 5 years of experience building web applications and digital solutions. I specialize in JavaScript technologies including React, Node.js, and modern frontend frameworks.

My journey in technology started during my computer science studies at the University of Nairobi, where I developed a strong foundation in software engineering principles. Since then, I've worked with startups and established companies to create impactful digital products.

I'm deeply committed to the open-source community and have contributed to several projects. When I'm not coding, I enjoy mentoring aspiring developers, writing technical articles, and exploring new technologies that can solve real-world problems.

My approach combines technical expertise with creative problem-solving to deliver solutions that are both functional and user-friendly.
