"Read/Write HEX File from Arduino Pro Mini (Delhi NCR Preferred)

Project Description
I am looking for an embedded systems developer with experience in Arduino and AVR microcontrollers to help with the following tasks:

Read HEX file from an existing Arduino Pro Mini board (ATmega328P).

Write (upload) HEX file back to the Arduino Pro Mini using a programmer (USBasp / FTDI / Arduino ISP).

Provide a step-by-step process/documentation so I can replicate the read/write process in the future.

Help troubleshoot any programmer/driver issues (e.g., AVRDude errors, sync issues, missing programmer errors).

Technical Requirements

Strong knowledge of Arduino Pro Mini (ATmega328P) bootloader and memory mapping.

Experience with AVRDude, Arduino IDE, and command-line tools for reading/writing HEX files.

Familiarity with USBasp / FTDI / Arduino ISP programmers.

Ability to verify successful backup and restore of firmware.

Preferred Location
Developer/freelancer should be based in Delhi NCR (India) for smooth communication and, if required, in-person hardware debugging.

Deliverables
Successfully extract the HEX file from Arduino Pro Mini.

Re-flash/write the HEX file back to another Arduino Pro Mini.

Provide clear documentation or video walkthrough of the process.

Support in resolving any programmer or driver errors." (client-provided description)
