At Mantra Softech, I build C/C++ and Qt/QML applications for biometric authentication systems, including Linux-based access control, attendance, and security devices. I've delivered WebRTC real-time audio and video communication, Wi-Fi and BLE connectivity, and high-performance multi-threaded communication modules using TCP/IP, UDP, and MQTT.
I've contributed to the Indian Navy AFSAC access-control system and developed embedded solutions including a smart video doorbell and MACE access-control device. My work spans Embedded Linux, secure media streaming, NAT traversal, SQLite, REST APIs, OpenSSL, hardware integration, and responsive device interfaces with LVGL.
