Embedded Systems & IoT | STM32 | ESP32 | FreeRTOS | C/C++

I’m Ajij Jambughoda, an Embedded Systems Engineer with over 3+ years of hands-on experience in designing and developing real-time embedded solutions for IoT, industrial automation, and smart electronics.

I specialize in working with microcontrollers like STM32 (ARM Cortex-M), ESP32, and PIC16F, using C, C++, and Embedded C. I’ve delivered projects involving FreeRTOS, secure communication protocols (AES-256, mbedTLS, HTTPS), and custom hardware driver development.
My key skills include: Real-time system development with FreeRTOS,Integration of sensors, GSM, LoRa, GPS, Bluetooth, RFID, GUI design with DWIN touch displays, LCDs, and audio modules,Protocols: UART, SPI, I2C, RS232
Tools: Keil uVision, STM32CubeMX, Espressif IDE, Proteus

I’ve worked on a variety of innovative solutions, including:
Wireless Fire Alarm Systems
IoT-based Home Automation
Industrial Signal Repeaters
Addressable Zone Controllers.
