I am writing to express my strong interest in your Embedded Engineer opening. With over 4 years of hands-on experience in embedded software development, I have a deep proficiency in Embedded C/C++ and extensive experience with the specific microcontrollers you listed. Why I am a Great Fit: Microcontroller Expertise: I have successfully delivered commercial projects using STM32 (HAL/LL drivers), ESP32 (IDF/Arduino), NXP (LPC/Kinetis series), and Silicon Labs (EFR32/Gecko). I am comfortable porting code between these platforms. Communication Protocols: My background includes implementing robust drivers for I2C, SPI, UART, RS485, and CAN. I have experience debugging these at the signal level using logic analyzers. Independence & Reliability: I specialize in taking ownership of modules-from driver development to application logic-requiring minimal supervision. I am fully available to dedicate 25-30 hours per week to your project. Regarding Location: I noticed the requirement for candidates to be based in India. I am currently based in Sri Lanka, which shares the same time zone (IST) and work culture. I have a stable high-speed internet connection and a fully equipped lab to handle remote hardware development seamlessly. I would appreciate it if you could consider my application based on my technical fit and ability to deliver quality results during your required hours. I am eager to discuss how my skills align with your current project needs. Best regards, Hemakanth

@jhonh128

Hello - I have full experiences with STM32, ESP32 ... - Good experience in Embedded C and C++(Cube) - Working experience with serial communication protocols(UART) This project is definitely for me. The opportunity for me to collaborate with you will soon become an opportunity for you to succeed in the project. The only difficulty is that I don't live in India, but we can certainly find a way together. (I already have ESP32 and STM development kits.) Let's go to success with me!!!
