ESP32 Gateway Development in Bangalore

I am looking for an experienced ESP32 developer based in Bangalore to develop a small webserver on an ESP32 gateway device. The ESP32 gateway includes a LoRa SX1262 module and a 7Semi Quectel 4G module. The project involves the following key functionalities:1) The ESP32 gateway normally runs headless. When a user presses a button, it should start a local webserver providing 2-3 webpages accessible via ESP32 WiFi. User changes on these pages must be saved to the ESP32 file system.2) The gateway receives packets from various wireless devices via LoRa SX1262, each device having a unique ID.3) Every 10 minutes, the gateway should send all accumulated LoRa packets to a customer’s internet webserver via a URL using the 4G module connected through UART. Deliverables:ESP32 firmware implementing the described webserver and communication functionalities. Webpages served by the ESP32 with user interface to view and modify settings. Reliable LoRa packet reception and storage mechanism. Periodic transmission of collected data over 4G to the remote webserver. Documentation for setup, usage, and code explanation. Only developers located in Bangalore will be considered. Other locations, please dont send proposals as I cant ship my hardware to other locations. Time is 3 weeks. Developer needs to have minimum 2 years experience. At least used once ESP32, HTML, C/C++, 4G, LoRa. Multiple iteration of development will be needed. Developers not confident of providing tested and bug free code need not apply. Some code is already available. Arduino environment has to be used.
