• Architected and developed a production-grade C++ IoT edge platform enabling secure device-to-cloud communication across pharmaceutical and industrial environments.
• Engineered a multi-threaded communication framework integrating Modbus TCP/IP, SSH, Telnet, WebSocket, BLE (BlueZ HCI), GraphQL, MQTT, and raw TCP/IP for 10+ industrial devices.
• Designed REST and MQTT-based telemetry services processing millions of device readings monthly with 99.9% production uptime.
• Implemented state-machine-driven task manager.
• Built C-based device simulators (Modbus, SSH, WebSocket, TCP) reducing hardware dependency and QA cycle time by 40%.
• Developed BLE beacon scanner using BlueZ HCI with iBeacon decoding and RSSI-based distance estimation; integrated NEO-6M GPS via UART for real-time hub tracking.
• Built multi-threaded REST services delivering real-time telemetry and location data in standardized JSON format.
• Designed C++/CLI interop wrapper bridging native C++ and .NET libraries; delivered high-availability Windows Service with dynamic DLL loading and 99% uptime.
• Implemented and maintained GoogleTest-based unit tests for C++ utility and task-management modules, improving code validation and reducing regression risk during feature changes.
• Deployed containerized edge solutions using Docker and CMake across Ubuntu Linux, Raspberry Pi (Zero 2W, Pi 5), Cisco IR829, and Supermicro, improving real-time processing performance by 45%.
