Digital Document Workflow System for Public Sector

Digital Document Workflow System for Public Sector

Designed and developed a full-stack web application to digitize the workflow of incoming and outgoing official documents. Built with Laravel and Bootstrap, the system replaces inefficient paper-based processes with a streamlined digital solution that supports secure storage, fast retrieval, and seamless editing. By eliminating manual data entry and physical handling, the application significantly improves operational reliability and minimizes the risk of data loss. The system also features role-based access control and activity logging, ensuring accountability and traceability throughout the document lifecycle.

Real-Time Power Analytics Dashboard with PostgreSQL & Looker Studio

Real-Time Power Analytics Dashboard with PostgreSQL & Looker Studio

Engineered a dynamic data visualization dashboard to monitor and report power usage across multiple industrial units. Leveraging PostgreSQL as the backend data source and Google Looker Studio for real-time dashboards, the solution tracks consumption against contractual thresholds using live telemetry data. This tool empowers stakeholders with instant insights into over-limit usage, system performance anomalies, and energy efficiency trends. Additionally, I implemented automated reporting pipelines and anomaly detection logic to support both technical diagnostics and strategic energy planning.

Advanced Multi-Factor Authentication with TOTP & AES-128 Encryption

Advanced Multi-Factor Authentication with TOTP & AES-128 Encryption

Built a robust authentication system that integrates Google OAuth 2.0 with Time-Based One-Time Password (TOTP) verification for enhanced account security. The system includes AES-128 encryption for JSON Web Tokens (JWT), providing secure session management and tamper-proof user data. To ensure resilience against common attack vectors, the system was stress-tested against brute-force, dictionary, and MITM scenarios. With built-in rate limiting and session validation, the implementation ensures only verified users can access protected resources, setting a strong foundation for secure user authentication in modern web applications.
