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.

NexOffice ERP is a comprehensive web-based Enterprise Resource Planning (ERP) platform designed to centralize and automate business operations across multiple departments within an organization. Developed using React, Firebase, and a modular architecture, the platform enables companies to manage their operational workflows through a single, scalable application.

The platform includes a complete Inventory Management module featuring stock control, warehouse stocktaking, borrowing management, automated inventory updates, Excel reporting, and low-stock notifications. Its HR Workspace provides GPS-based attendance with webcam verification, employee database management, payroll slips, KPI evaluation, disciplinary reporting, and customizable employee request forms.

Beyond HR and inventory, NexOffice ERP offers a comprehensive General Office suite with company calendars, announcements, internal group chat, vehicle booking, employee recognition, and a centralized Notification & Approval Center for handling approvals across multiple business processes

For IT departments, the integrated Helpdesk & Ticketing System supports SLA monitoring, priority-based ticket management, technician assignment, customer satisfaction ratings, and performance analytics. The platform also incorporates Office Automation capabilities, allowing administrators to build visual workflows, configure AI agents, automate Telegram notifications, and deploy intelligent chatbot pre-filtering to reduce unnecessary API usage.

Security is reinforced through OTP-based authentication, Credential Gate protection, secure API key handling, session management, audit logging, and role-based access control. Additionally, Progressive Web App (PWA) support enables offline operation with automatic synchronization once connectivity is restored. control. Additionally, Progressive Web App (PWA) support enables offline operation with automatic synchronization once connectivity is restored.

By combining HR Management, Inventory, Asset Management, Office Administration, IT Service Management, Workflow Automation, and AI-powered business tools into a single ecosystem, NexOffice ERP helps organizations improve productivity, enhance collaboration, reduce manual processes, and accelerate digital transformation across the enterprise.

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.

Home and building automation setups often require connecting highly diverse systems (MQTT devices, custom HTTP hooks, databases) to a single, intuitive interface. Managing configurations dynamically shouldn't require code changes. I built NexHome to give administrators a flexible, web-based control room.

The platform enables users to organize devices into custom pages (e.g., Office, Server Room, Residential areas) and drag-and-drop live widgets like switches, dials, real-time log viewers, and graphs. Under the hood, an event-driven rule builder triggers automated responses when metrics cross critical thresholds.

NexHome was designed with modularity in mind. Its React frontend connects via WebSockets to an MQTT broker, providing instant updates on sensor states and electrical loads, while utilizing Firebase Firestore to persist custom dashboard arrangements and user preferences.
