anyone got code for an inverter driver?

hi, im looking for esp32 code for a sine wave pcm inverter, 3 phase or single phase, hopefully with pwm and analogue feedback.
if such does not yet exist, is there anyone willing to write it for a small fee?
there is plenty of code for pic, arduino etc and im sure it can be transferred easy but im not that great at even simple coding yet.
my ideal would be with a small oled to show status, switchable single or 3 phase, analogue feedback to control pwm (through a potentiometer so i can control overall voltage output, with a rotary encoder to set frequency.
it will need a programmable delay to ensure no 2 igbt modules are active at the same time (kaboom!)
a simple web interface would be an affordable luxury!
i am sure a program like this would have a very wide appeal to other constructors as it could be used not only for solar power projects, machine/cnc control, but even such esoteric uses such as a massively powerful class d audio amp, and given the right output stage and filtering, a possible ham radio transmitter! whatever modulation source you decide to feed into the feedback input. maybe even accept input via bluetooth or wifi....but maybe im taking it too far now!
switching frequency should be available from dc, to whatever maximum an esp32 can handle.
