These Mentorship Spotlights highlight the work done by the Mentors and the Mentees as part of their program participation.

It gave me knowledge of many things: internal operations of the open source community, architecture of Iroha blockchain, working with protobufs and many more technical details. But it was also great dose of knowledge about my soft skills. By working with the Hyperledger Iroha code, I managed to get my first work, but also I learned about many academic opportunities connected with the Hyperledger community. My mentor, Mr. Grzegorz Bazior, was great help in planning and organizing things. His experience and broad view made exploring solutions easier and let me add some extras to my project.” Mentor [image_with_animation image_url=”116022″ image_size=”full” animation_type=”entrance” animation=”Fade In” hover_animation=”none” alignment=”” border_radius=”none” box_shadow=”none” image_loading=”default” max_width=”100%” max_width_mobile=”default”] Grzegorz Bazior Yonix Digital Systems AGH University of Science and Technology “I was invited to be a Hyperledger Iroha maintainer five months ago and then I was asked to be mentor. It was my first time being mentor of an open source project. I work as academic teacher, so I’m used to observing students learning and making progress. Being a mentor is different – we can observe progress of useful practical project from beginning until end. It takes time, but it is worth of all that effort when the project is finally completed and is great quality work. Piotr is a student who was attending my lessons at the university where I teach. I saw that he was using many things he has learned from me at the university. He was making all the changes much faster then the mentorship plan called for. What is more, after finishing everything, he started work on another mentorship project. He learned how to work together with the community as well as with multiple technologies and completed all his work. It was a great experience and pleasure to be Piotr’s mentor.” A special thanks to the Hyperledger member companies for funding this important program.
