ESP32 Data Logger.

I have a project for an ESP32 Data Logger. This data logger will be used to log encoded data from an ECU to a MicroSD card.Currently data is stored to MicroSd card with no issues. What I need is to be able to save this data in 24hrs increments & user be able to select available data and plot on a Graph. It is important that this project is completed as soon as possible (ASAP). With the right freelancer, this should be a relatively straightforward job. Professionalism and communication is a must. Prior experience with similar projects is a definite plus. If you are the right person for this, please don't hesitate to get in touch. Thanks for your time.
Esp32 runs on APMode (no internet) & host a web server. (all of it is working)
