With over four years of experience in web development and digital technology instruction, I specialize in creating user-friendly, scalable web applications that align with both client and user needs. Most recently, as a Freelance Full-Stack Developer, I demonstrated a commitment to delivering innovative solutions through expertise in React, Firebase, and responsive design. My goal is to contribute to projects that prioritize seamless digital experiences and operational efficiency. During my recent freelance project, I designed and developed a responsive full-stack web application using React, JavaScript, HTML, and CSS. Cloud integration was achieved through Firebase Firestore, enabling secure, real-time data storage and dynamic content rendering, while Git/GitHub ensured seamless deployment and version control. My focus remains on delivering high-quality, performance-optimized solutions that meet evolving technical needs.
