FinTech Engineering
Building financial systems requires:
- Absolute reliability: transactions cannot fail silently
- Audit trails: every action must be traceable
- Security: encryption and access control are non-negotiable
- Compliance: regulatory requirements vary by jurisdiction
This experience gave me deep appreciation for mission-critical system design.
