Iot gps software development

I'm looking for an experienced software developer to create an IoT GPS software for me. I need the software to be web-based and to include a real-time tracking feature. I don't need any existing systems or software to be integrated with this solution. My ideal candidate has experience in developing IoT GPS software, and should provide examples of their work to demonstrate their ability to meet my requirements. Please respond with any questions or comments. Thank you for your time.
