I'm a 3rd-year B.Tech CSE (Honours) student at JNTU Kakinada (CGPA 8.28) building intelligent Android applications at Karna Digital — my personal indie developer brand. I combine mobile engineering with AI to create privacy-first, production-ready apps that ship on Google Play Store. I focus on:

• 📱 Android development with Kotlin & Jetpack Compose
• 🤖 AI integration (LLMs, Gemini API, prompt engineering)

Native Android PDF utility suite with 20+ offline tools

• Features: PDF splitting, merging, compression, OCR, watermarking, image-to-PDF, HTML conversion
• Tech Stack: Kotlin, Android Studio, Material Design 3, Apache PDFBox
• Impact: 5000+ users, featured in HowToMen YouTube (8.8L subscribers)
• GitHub: Karna14314/Pdf_Tools
• Play Store: PDF Toolkit

AI research paper analysis platform with semantic search and RAG

• Features: PDF parsing, FAISS vector search, multi-document Q&A, Gemini API integration
• Tech Stack: Python, Streamlit, Gemini API, pdfplumber, FAISS
• GitHub: https://github.com/Karna14314/PaperIQ_Research-Paper-Analysis.git
