Cloud File Transfer Platform
About the client
Andersen's customer, in this business case, was a globally active provider of data services. The company enables its end-users to share large files beyond the limits of traditional email and messaging services. By leveraging blockchain technology, it supports decentralized storage and enables transactions with its own cryptocurrency token. With advanced security standards, the company is setting new benchmarks in the field of encrypted file sharing.
Business Context
As already mentioned, the customer aimed to revolutionize secure file transfer operations by leveraging decentralized blockchain technologies. In order to achieve this, they sought to obtain a modern cloud file transfer platform that would integrate Web3-based storage, crypto payments, and advanced security measures. Andersen was entrusted with engineering a scalable solution, building upon a microservice architecture. Our mission was to ensure seamless integration of decentralized authentication, encrypted data transfer, and multi-layered security. That is, by combining blockchain technologies with cloud storage, the resulting platform was expected to offer a unique blend of privacy, flexibility, and performance, setting a new industry standard.
Challenges
The primary project goal was to develop a new system, applying a modern tech stack while incorporating blockchain technologies to enhance security and UX.
