About Yasir
Embedded Engineer | ESP32, STM32, Embedded Linux, PCB Design, IoT
Ilmenau, Germany - 2:19 pm local time
With professional industry experience in embedded development — not just hobby projects — I specialize in building reliable, scalable solutions for IoT, industrial automation, robotics, and custom electronic products. Every deliverable I produce is built to survive real operating conditions, not just pass a bench test.
Core Expertise:
Embedded firmware development in C/C++ — bare-metal and RTOS-based (FreeRTOS, Zephyr)
ESP32, STM32, ARM Cortex-M microcontrollers
Embedded Linux development with Yocto and Buildroot
Linux kernel customization and device driver development
BSP development and Linux system integration
Custom PCB design — KiCad, Eagle, Altium Designer
Schematic design and multilayer PCB layout
Communication protocols — UART, SPI, I2C, CAN, BLE, Wi-Fi, MQTT, Ethernet
Sensor and actuator integration
Production-ready hardware and software prototyping
What I Deliver:
Complete embedded systems from concept to deployment
Embedded Linux platforms built for production
Yocto and Buildroot BSP development
Linux kernel modules and device drivers
PCB schematics and layouts ready for manufacturing
Firmware development and optimization
IoT product development end to end
System debugging and performance optimization
I provide full-cycle embedded engineering support — from architecture and prototyping through firmware, hardware, and production deployment — with clean code, thorough documentation, and reliable communication throughout.
If you need an experienced engineer who can handle both hardware and software, including low-level Linux systems, production firmware, and manufacturable electronics — let's talk.
