About me.

My journey in web development began in 2022 during my first year of college, when I was tasked with creating a personal website. That project introduced me to HTML and CSS, sparking my curiosity and passion for web development.

From there, I delved deeper into JavaScript and its frameworks, eventually discovering the MERN stack. I started by studying and applying it to mock projects, which helped me build a solid foundation. After my first year of college, I landed an internship where I utilized the MERN stack to contribute to real-world projects, gaining invaluable experience and confidence.

Since then, I've worked on personal projects to refine my skills and have taken on freelance opportunities to help clients bring their ideas to life.
