The finish and wood choice steer me away from thinking Chinese/AliExpress/etc. I'd bet it's a homemade job.
It looks very well made for a budget build. The body looks like ash and the finish looks like polyurethane. I wish you could take some headstock shots so that we can see what style of truss rod type is used in the neck. It looks like a cool bass and i'll bet that it sounds great.
Sadly, as interesting as it sounds, it is way out of my scope of practice. It sounds as good as it is heavy.
