Experience

Customs: Track and Trace

This application built on Hyperledger Fabric traces the movement of goods moving in and out of customs’ warehouses operated by different vendors. The information is shared with revenue services and foreign customs if a transaction involves them. I designed the solution, including the integration with core systems—used features from Hyperledger Fabric, such as attribute-based access control and private data collections.

Patent Chain

Patent Chain can prevent issues such as documentary fraud and allow for the digitization of assets. The project was developed using Sopra Steria’s IP “Document Management System” on blockchain. I was involved in the requirements gathering and providing solutions using the Hyperledger Fabric platform.

Identity Management

The solution was built to empower individuals to manage access to their personal data via the public blockchain Ethereum. The data proof aimed to work using zero knowledge proof principles and help customers comply with GDPR rules.
