H2020 EU Qualichain 🇪🇺
January 2020 - December 2020
Developed at INESC-ID, Lisbon, Portugal

Participating in an H2020 European Project: Qualichain: Decentralised Qualifications on the Blockchain.
My work includes research and development on several components of the project, including:
- research on self sovereign identity (verifiable credentials, decentralized identifiers, standards)
- research on distributed access control
- dApp development (Solidiy smart contracts, Ethereum, VueJs, NodeJs, deployment)
Code is available here

September 2018 - April 2020
Developed at the Portuguese Justice, Lisbon, Portugal

Working along the Portuguese government to improve the status quo by leveraging the blockchain technology. The solution provides an ontology to standardize access control logs and aims to secure Justice data.

Interacted closely with the top technical management of IGFEJ to satisfy level production configuration. This work included:
-The study of processes at the Portuguese justice
-Conceptualization of a blockchain-based solution to improve it
-Development of two blockchain-based solutions, with Hyperledger Composer and Hyperledger Fabric 2.2
-Development: smart contracts, web server (NodeJS, blockchain client), user interface (VueJS)
-Operations: deployment of the infrastructure at IGFEJ servers, operation utilities, documentation, and testing

This project yielded my master thesis, two scientific papers, and a working proof of concept, close to production-level, and ready to be activated.

Enterprise Blockchain Technologies - Hyperledger Fabric University Course
June 2020 - November 2020
Developed at the Linux Foundation (Remote), USA
A growing part of our community is our partnership with academia. Hyperledger Fabric and other Hyperledger projects are being incorporated in to research and education in universities more and more all over the world. Hyperledger can aid the growth by preparing study materials, sample lab experiments and quizzes and tests that teach computer science students about distributed systems and consensus algorithms and cryptography.

Hyperledger Umbra has streamlined the process of setting up a full Hyperledger Fabric network running on a single computer. It provides an ideal environment for students to learn Hyperledger Fabric administration as well as use it for running lab experiments and learning exercises.

This mentorship is focused on producing a "classroom-in-a-box" for an introductory computer science course on distributed systems and algorithms that can be offered to universities that wish to use Hyperledger Fabric in their curriculum.
