Hello, my name is Shivakant Shukla, and I am a MERN stack developer with four years of experience in creating dynamic and user-friendly web applications. My passion for technology, coupled with a strong foundation in front-end development, has been the driving force behind my career. In the realm of Front-end development, I excel in crafting interactive and responsive user interfaces using technologies such as React, Redux, JavaScript, HTML5, and CSS3. I take pride in my ability to transform design concepts into functional, pixel-perfect websites that provide exceptional user experiences. Whether it's optimising performance, ensuring cross-browser compatibility, or enhancing accessibility, I am committed to delivering high-quality front-end solutions. While my primary expertise lies in front-end development, I have had the opportunity to work with back-end technologies like Node.js, Express.js, Nest.js, and MongoDB.
