Hello, my name is Ihar, nice to meet you.
I have read your requirements carefully and feel confident in my skills because my experience in mobile development more than 7 years. I know very well how BLE works since I had several projects with BLE, for example tracking cars with Beacon devices. Please let me know, if you are interested in checking my skills and have an interview with me.
Thanks for your time.
Best regards,
Ihar
