Embedded Engineer Team for Prototype Development

I'm looking for an experienced embedded engineer team based in India to help prototype and code both hardware and firmware.

Key Requirements:
- Develop an embedded system for a unique radio application.
- System interaction with sensors, actuators, and wireless modules.
- Firmware development primarily in C/C++.

Ideal Skills and Experience:
- Proficiency in hardware and firmware development.
- Experience with a variety of sensors, actuators, and wireless communication protocols.
- Strong programming skills in C/C++.
- Ability to work collaboratively and meet project deadlines.

Please provide relevant experience and approach in your bids.

The area I want to try is GSM, UWB , Lora and BLE. I will pay project wise only. Initially I will keep a cap of 10000 INR per project and after successfully completing each project increase budget for next projects.

I will like review of project in between and each project duration initially will be < 4 weeks and will increase in subsequent projects.

Will need all code documented and design so I can take it forward in future if support is not available.
