What I'm looking for

I'm looking to build secure, connected systems across embedded devices, Linux, Android, and IoT platforms, where I can contribute hands-on C++ and platform engineering work while continuing to deepen my systems expertise.

At ISD High Technology, I build C++ and Java system components for customized Android environments, including native services, AOSP integrations, and SELinux-secured services. I also designed an MQTT-based push notification system to replace Firebase Cloud Messaging with independent, secure real-time device communication.

My work connects embedded devices, Linux systems, and application layers. I've developed ESP32 IoT solutions with ESP-IDF and RTOS concepts, and maintained Docker-based Linux development and deployment environments.

At STMicroelectronics, I strengthened my low-level Linux foundation through processes, memory management, IPC, sockets, namespaces, cgroups, and virtualization. I built a user-space memory allocator and a Unix-like shell, while exploring AF_INET, CAN, and Bluetooth communication.

I also teach Embedded Linux and Modern C++, helping students build embedded Linux systems with Yocto Project and Raspberry Pi. My projects include a security-hardened Android ROM, an Android/Linux network daemon, IoT monitoring platforms, and a Qt6 application for ZigBee network visualization and control.
