Ch32v003f4 Microcontroller Programmer Needed

I am looking for a skilled microcontroller programmer who has experience with the Ch32v003f4 microcontroller.

I'm looking for a programmer - freelancer for make me a code for CH32V003 core

Program should be better at Arduino IDE ...... But Mounriver could be ok

Circuit will work with battery 18650 - 3,7V, Low power consuptiom it's the target

Pins from CH32V033 is not defined .. Free for choice

Basic I have transmitter and receiver using IR, distance between close 0.5m up to 1m trasnmitter and receiver

TRASMITTER function

Turn on micronctroller from mechanical switch

start to send IR signal for 10 sec.

After 10 seconds go to sleeep for save battery

keep on sleep until to mechanical switch turn off microcontroller ..... It means 30sec more or less

RECEIVER function.

Receive ir signal

get value from trimpot 1

get value from trimpot 2

wait time set by trimpot 1

power on a small pump with time set on trimpot 2

back to initial condition

For save battery because IR receiver has 20mA ...... I powered on 1 sec. and power off 5Sec, on the power off state I put microcontroller for sleep to save battery as much as possible

i shared my flowchart for see in details what we should to do on the program.
