I can relate to your approach. Engineers have a tendency to allow the "not invented here syndrome" take hold.

But ... that is not necessarily a bad thing. It is possible that you are more passionate and motivated by the technical aspects. If your product and the niche that it serves doesn't stir the same intensity of passion then maybe you should consider amping up your skills in the infrastructure side and finding lucrative gigs in that area. If you decide to change track in the future, your current business might be a viable sale proposition. The new owner might need you to maintain the infrastructure on contract.

Money is good, but once your basic needs are met it doesn't buy more happiness. In the long term you are more successful if you do what you are good at and enjoy doing.
