Frequently Asked Questions
How do you ensure transaction data is never lost?
I utilize PostgreSQL with strict ACID transactions, ensuring that financial debits and credits either completely succeed together or completely roll back if an error occurs.
Are your React Native apps secure enough for Fintech?
Yes, I implement secure keystores, prevent screen recording/screenshots on sensitive views, and obfuscate the JavaScript bundle for maximum security.
