I spend 10+ years with Java enterprise application development, and it ranges in multiple industries, e.g., Financial, FinTech, eCommerce, and manufacturing industry etc.

Trust me, the similarity of these industries in terms of technology stack is beyond what you think.

Surprisingly (Even now), over the last 3 years, I see most of the companies I've worked/consulted with has (or at least a plan) to move their monolithic application to micro-service architecture.
