Architected a highly concurrent Deep Packet Inspection (DPI) engine in C++ to parse raw PCAP network traffic and extract Server Name Indication (SNI) data from encrypted TLS handshakes. Engineered a multi-threaded processing pipeline utilising custom Load Balancers, Fast Paths, and thread-safe queues to efficiently scale packet inspection across multiple CPU cores. Implemented stateful flow tracking and a custom rules-based filtering system capable of detecting and dropping specific connections based on IP, domain, and application signatures.

Developed a cross-platform mobile security tool in Flutter to identify and analyze potentially harmful Android applications. Engineered a scanning engine that detects sensitive permissions and suspicious behaviour patterns to generate detailed security reports.

Architected an offline-first, privacy-focused note-taking application ensuring complete data sovereignty. Implemented advanced local encryption and biometric authentication to secure data directly on device storage.

Built a utility tool that automates the conversion of educational video content into readable PDF documents. Utilised Python for backend processing to accurately extract frames and subtitles for structured study material. Integrated Java and HTML to format the final document output for improved readability.
