Hello Hustler..

There are 2 kind of problems that people solve. Aspirin or Vitamin. The product road-map (from an engineering point of view) depends on this.

If you building something that is so unique and solving a crazy problem (E.g app that tell's what is your girlfriend thinking now capturing her brain waves from distance !!) you don't need to concentrate on the UX. UX is expensive and in some cases very important. In this case, the feature (MVP or minimim markatable product) is the key.

If you are building another burger joint or calorie tracking app or ride share, the UX is a big make/break factor .

Best is to hire someone who has more programming (engineering) experience and have enough understanding of the design aspects.

For your design needs, get it freelanced (cheaper)

Validate your MVP and and if there is $$$ coming, put it on improving the quality and experience which includes
- better UX
- scalable backends etc...

Call me if you need any help.
