Hihi.
Wild shot here, but every mass (!) electronics product these days comes with Cloud part

I'm experienced cloud platform engineer, AWS only, no GCP or Azure please. I've been doing it for 10 years, certified. Can create multi-account infrastructure for both startups and mid-size companies. I prefer AWS CloudFormation to code the infrastructure compared to Terraform.
On-prem infra is no problem, we'll link those with AWS VPCs. I know networking well, and Linux/BSD.
I also have intimate knowledge of AWS APIs and use it in anger with Python (asyncio and Boto3). AU citizen, available now

I will code and deploy the REST APIs your product needs. Scalable and indestructable. Secure.
Cheers!
