👨‍💻 About Me

I’m an Embedded Systems Engineer with 8+ years of experience architecting and developing real-time, secure, and scalable firmware for IoT devices and industrial systems.

I specialize in STM32, Renesas RA, PIC32, Zephyr, and FreeRTOS. My expertise includes secure OTA, bootloaders, BLE, LoRa, and MQTT, with strict compliance to MISRA C and OWASP IoT standards.

I've built full-stack solutions, automation tools in C#/Qt, and worked across the entire lifecycle — from firmware to cloud to web integration.
