I am an engineer with masters in signals and image processing. I have worked on several projects related to computer vision and image processing that includes medical imagery, MRI, ECG, brain controlled devices, activity recognition etc. I can easily estimate heart rate from PPG data. Just provide me more requirements if you have any. I will start right away once you confirm. My work is always high quality and delivered on time. By working on your project, I wish to make a happy client out of you and will love to work with you again on other projects. Just ping me and lets get it done. Cheers
