πŸš€ About Me

πŸŽ“ B.Tech graduate in Computer Science and Engineering

πŸ’‘ Interested in Software Development, IT Systems, Application Development, Cloud Services, Troubleshooting, Testing and Emerging Technologies

πŸ› οΈ I enjoy building practical projects and learning how complete software systems work β€” from user interfaces and databases to deployment and distribution.

πŸ€– I actively use AI-assisted development tools to accelerate development, understand unfamiliar technologies, troubleshoot problems and convert ideas into functional applications.

πŸ”§ I particularly enjoy system troubleshooting and problem solving, including investigating software issues, configuration problems, application errors and deployment challenges.

πŸ“± My projects include Web Applications, Android Applications, Desktop Software, Cloud-Connected Applications and Academic Prototypes.

🌱 I continuously improve my technical knowledge by building, testing, debugging and documenting real projects.


🧠 Technical Exposure

Languages & Frontend

TypeScript JavaScript HTML5 CSS3

Frameworks & Application Development

React Vite Tailwind CSS Electron Capacitor

Backend, Database & Cloud

Firebase SQLite Cloudflare

Development Tools

Git GitHub VS Code Android Studio

Note: My experience with these technologies comes primarily from project-based and AI-assisted development. I focus on understanding application workflows, integration, debugging, testing, deployment and practical implementation while continuously strengthening my core programming knowledge.
