NexVault is a secure cloud-based password manager engineered to protect and organize digital credentials through a modern, intuitive web interface. Built with React, Vite, Firebase Realtime Database, and AES encryption, the platform enables users to securely store, manage, and access passwords across multiple devices while maintaining a clean and responsive user experience.

It features end-to-end client-side AES encryption, ensuring sensitive credentials are encrypted before being synchronized to the cloud. Smart account categorization, instant search, password masking, clipboard integration, and full CRUD operations streamline credential management without compromising usability.

The application also incorporates Firebase Authentication for secure user access, real-time cloud synchronization, and a modular architecture designed for scalability and maintainability. With a modern vault-inspired interface, reusable React components, and optimized state management, NexVault delivers a fast, reliable, and secure password management experience for everyday users.

On real sites, supervisory platforms like Niagara 4 license by device and point count — and the quota rarely matches what the project actually needs. Re-licensing isn't always an option, so I built NexGate myself to solve it.

APP_1 discovers field devices across BACnet, Modbus, MQTT, and SNMP, then republishes them back to the supervisor as a single virtualized BACnet device — or consolidates dozens of points into one optimized string object. The supervisor sees one device; APP_1 handles the translation underneath.

What started as a licensing workaround grew into a full commissioning and protocol-testing toolkit I now rely on across multiple sites — covering BACnet discovery, MQTT telemetry simulation, Modbus integration checks, SNMP validation, and psychrometric chart-based HVAC control logic.
