Challenges

A multitenant platform that provides digital document signing and storage for business and individual users. The high-level security is achieved via identity verification of users/companies, multi-factor authentication, and audit logs. Signatures are created with secure-stored self-signed certificates and/or cloud KMS.

The biggest challenge was to assemble a reusable architecture of services on both front-end and back-end, which allowed us to achieve multitenancy, security, and flexibility for solving diverse customer use cases.
