About This Project
NDSecure is a cutting-edge encrypted note-sharing platform designed for users who prioritize security without compromising performance. The application features end-to-end AES-256 encryption, ensuring that sensitive information remains protected at all times. Self-destructing notes provide an additional layer of security by automatically removing content after specified time periods or read counts. The platform is engineered to handle over 1,000 concurrent users while maintaining sub-200ms retrieval times, making it both secure and highly performant.

Challenges & Solutions
Balancing strong encryption with high performance was the primary challenge. Implementing self-destructing notes while maintaining data integrity and ensuring the system could handle high concurrent loads required careful architecture planning.
Optimized the encryption/decryption process by implementing efficient key management and caching strategies. Used connection pooling and database indexing to maintain fast retrieval times even under high load.
Key Learnings
Gained deep insights into cryptographic implementations and performance optimization techniques. Understanding the importance of security-first design while maintaining excellent user experience.
