Welcome CodeHavens

👨‍💻 About Me

Hello! I'm Vaibhav, a passionate and curious developer from India, dedicated to building innovative, user-focused digital experiences.

I specialize in both Frontend and Backend Development, and I’m actively growing as a full MERN Stack Developer.

From sleek web interfaces to intelligent automation scripts and offline-first Android apps, I love blending design, logic, and usability into everything I build.

🔧 I believe in a development philosophy that values creativity, clean architecture, and real-world problem solving—turning ideas into tools that matter.

Main focus areas:

• Crafting responsive and modern web applications
• Building native Android apps with Kotlin and Android Studio
• Creating RESTful APIs and integrating NoSQL/SQL backends
• Automating web workflows and testing with Selenium
• Solving algorithmic challenges and improving DSA skills

💡 I’m always exploring new technologies like AI tools, cloud integrations (Firebase, Vercel), and performance optimization techniques to stay ahead in the tech landscape.

Outside of coding, I enjoy contributing to open-source, learning about startup ecosystems, and sharing knowledge through meaningful projects and platforms.
