About Me

Hello! I'm Hari Krishna, a Web & Application Developer from India with a background in Electronics & Communication Engineering and hands-on experience building real-world web applications, websites, and mobile applications.

I also have working experience with React, JavaScript, HTML, CSS, MySQL, SQLite, Firebase, and Kotlin. My approach focuses on building reliable, responsive, and user-friendly solutions with clean and maintainable code.

I enjoy turning ideas and requirements into practical digital solutions, learning new technologies, and working on projects that solve real problems. I'm currently open to freelance and project-based opportunities where I can contribute to web development, application development, and backend solutions.
