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.
