🔧 Embedded Hardware Integration

🔐 Secure APIs & Encrypted Communication

• Designed RESTful APIs for fueling transactions, authentication, user access control, and audit logging

• Enabled encrypted TCP socket communication between site terminals and the central server

• Protected all sensitive data—including user IDs and fueling logs—via AES-256 encryption and client-side certificates

• Developed a proprietary dual-layer encryption and compression protocol that reduced payload sizes by 50–60% prior to transmission. Unlike conventional encryption methods that increase data size, our approach preserved security while optimizing bandwidth—contributing directly to an 80% reduction in cellular data usage

🔄 Synchronization & Real-Time Oversight

• Implemented role-based access control by department, user, vehicle, and site

• Enabled standalone localized mode at each site to maintain operations during network interruptions

• Introduced offline queuing with automatic sync to ensure all transactions were securely captured and transmitted

• Delivered real-time dashboards providing system health, tank status, and fueling activity visibility citywide

⚙ Performance Engineering

• Improved transaction speed by 300% through optimized data flow and high-efficiency SQL queries

• Replaced the legacy full-whitelist sync model with compressed, delta-based synchronization, powered by our custom encryption/compression layer

• Reduced redundant traffic and improved communication efficiency—resulting in an 80% drop in cellular data transmission

• Delivered a modular, scalable backend designed for low maintenance and seamless future expansion

The platform now powers one of the largest and most complex municipal fueling operations in the United States—with unmatched speed, visibility, and control.

• ✅ 99.5% system uptime, ensuring continuous fueling access for all city departments and emergency responders

• ⚡ 300% faster fueling terminal response and transaction speed

• 📉 80% reduction in data transmission load and cellular communication costs

• 🔐 Real-time, end-to-end encrypted data handling across 65 fueling locations and 50+ departments

• 🌐 Centralized audit, live monitoring, and full Veeder Root tank level integration

Fuel Theft Prevention & Cost Recovery

Real-time auditing, encrypted user validation, and fuel usage limits eliminated theft and misuse—saving the city hundreds of thousands annually.

Accurate Departmental Billing

Every transaction is now linked to the correct department and vehicle, enabling precise usage-based billing and improved interdepartmental cost forecasting.
