Ian Westmacott
Yaxi worked on my team at Amazon as a Sofware Development Engineer right out of school. Yaxi was with the team for 1.5 years and during that time he demonstrated strong curiosity and eagerness to learn new technologies and best practices. He worked hard and did not hesitate to bring new ideas and different perspectives to team discussions. He took ownership for all the team's artifacts, not just the ones he worked on, and he showed customer obsession in his designs and priorities. I would recommend Yaxi for any Software Engineering role.
