Hello Dear,
We have rich experience in Embedded System & IOTs. We have expertise on Linux on various TI, NXP, Qualcomm and Samsung SoCs. We also have rich experience in interfacing MCUs with Linux based SoCs. And also worked on 9-Axis AGM sensor, Heart Rate sensor, Temperature sensor, Smoke sensors and many more health related sensors. Only missing part is that we don't have web development experience but we can upload data in your choice XML or Txt or any other formatted file on any of your server by capturing sensors data from MSP432/430 or any MCUs or Arduino via Raspberry Pi.
I hope to get at least response from you to share our expertise and knowledge in this domain to make you product successful within your timeline.
