FinTech and Healthcare APIs handle highly sensitive data, financial records, personal identities, and health information. A single security flaw can lead to regulatory penalties, reputational damage, and loss of trust. These industries require APIs that are secure by design, compliant with regulations, and auditable end to end. We design and build secure APIs for FinTech and Healthcare using Django REST Framework or FastAPI, with strict security controls, compliance alignment, and reliability built into the architecture.
