4th sem wrapped up - looking back at some of the projects I got to build over the semester 📍 LawVista: AI Legal Assistant For our cloud computing course, we developed an AI-powered legal assistant using AgentFlow on Google Cloud. Instead of manually managing LLM backends or training a custom model, we leveraged AgentFlow to seamlessly orchestrate agent logic, memory, and API interactions. This approach let us focus on building legal workflows and user experience, while benefiting from the scalability and security of cloud infrastructure. 📍 Inventory Management System As part of our web programming curriculum, we designed and implemented a comprehensive inventory management platform using TypeScript and Firebase. The system featured distinct interfaces for employees, employers, and customers, supporting real-time tracking of raw materials like steel and graphite, as well as order management and workflow automation. Building this application deepened my understanding of structured data modeling, authentication with Firebase Auth, and designing scalable, real-time web apps. 📍 RFID Cloner with ESP32 In the Microprocessors and Microcontrollers course, I created a tool using the ESP32-S2 Mini and an RFID reader to read, store, and clone card data. This project involved low-level hardware interfacing via SPI/UART, implementing RFID protocols (ISO 14443A), and debugging embedded systems with serial monitors and logic analyzers. 📍 Pwnagotchi with Web UI + PCAP Analysis For our computer networks course, we built a Pwnagotchi-a device that uses AI to passively capture Wi-Fi handshakes for security research. We added a browser-based interface for activity visualization and used Wireshark to analyze PCAP files, which provided valuable insights into 802.11 frame structures, passive sniffing techniques, and the real-world security implications of wireless networks. We were able to capture about 20 handshakes within just 15 minutes of operation, highlighting the effectiveness of our setup. Each project this semester expanded my technical skill set-from cloud-native AI orchestration to embedded systems and network analysis. Grateful for the collaboration and support of my teammates, Souparno Nag and Naveen Bharath. Looking forward to more learning and building ahead!
