About Me

Hi, I'm Karan Kumar from Bihar, India. What started as curiosity about coding has turned into a 3+ year journey of building 15+ production applications that serve thousands of users worldwide.

From a Computer Science student experimenting with code to creating 3 npm packages with 1,800+ downloads, I've worked across the entire development spectrum. My experience spans startups, freelance projects, and full-time roles where I've consistently delivered solutions that solve real business problems.

I specialize in React Native and Next.js, but what sets me apart isn't just technical skills—it's my ability to understand business needs and translate them into scalable, user-friendly applications. Whether it's building a developer competition platform or creating API automation tools, I focus on measurable impact.

Currently, I'm focused on helping startups and businesses scale their digital presence through modern web and mobile solutions. I believe great software isn't just about clean code— it's about creating experiences that users love and businesses can rely on.

Outside of work, I like listening to music and reading books—it's how I recharge and find new inspiration.

If you're looking for someone who can help bring your website or app idea to life, I'm excited to connect and create something impactful together.
