Minecraft Mod Porting - Java

I require an Java developer to assist with updating a Minecraft Mod from version 1.16 to the newest version. . As there is no specific deadline, quality is paramount over speed.

I need to upgrade CustomNPCs and Replay mod for FORGE
CustomNPCs latest version is 1.16.5
Replay mod latest version is 1.12.2

I need both mods to be upgraded to 1.20.1 version

If you are experienced Minecraft developer, fell free to contact me.

This project may require deep debugging, code optimization, and intensive testing post-porting to ensure stability and optimal performance. Let's cherish the luxury of time we got here and aim for perfection.
