gps engineer

My project requires a GPS engineer with the expertise to design a GPS system with no specific technology or platform preferences. The ultimate purpose of the system is for tracking applications. I need someone who can create an effective solution based on my specific objectives. This includes organizing and managing GPS data as needed and developing software that will be used to track the data. The ideal candidate should have extensive knowledge and experience in the development and implementation of GPS systems and be well versed in coding and data analysis.
We already developed an GPS tracker system, however it stopped to work and we need someone to fix and improve it
