About

Hi, I’m Prince Kumar, a results-driven Full Stack Developer with over 16 years of experience creating scalable and user-centric web applications. I specialize in front-end development using React.js, Next.js, and Tailwind CSS, and I have hands-on expertise in backend technologies like Node.js and PostgreSQL. I enjoy building responsive, accessible, and optimized user interfaces that offer seamless user experiences.

Over the years, I have led projects modernizing legacy systems, integrated cloud services, and implemented secure authentication mechanisms. Working collaboratively in Agile teams, I thrive mentoring junior developers and delivering intuitive, pixel-perfect interfaces that meet business goals. I’m passionate about using the latest technologies to build high-quality digital products that users love.
