Which platform is best for fintech & finance websites?+

What should I ask a fintech & finance web developer in Istanbul before hiring?+

Ask about demonstrated understanding of FCA financial promotions rules; secure form handling for sensitive financial data; calculator and comparison tool architecture. Then ask for two or three live fintech & finance websites they built, who will actually work on yours, and what support looks like after launch.
