She always has been so professional, patient and generous when it was about helping out colleagues / workmates and developers! She never refused her time or work to help other people and take additional tasks! She was always on top of her goals helping everyone else to achieve theirs! And she even stepped into other languages making sure both sides (developers and Apple representatives) meet all the goals and guidelines! I highly recommend Lichao for any job as I truly believe any company will benefit having her on board! She is extremely team player and has such unique ability to help everyone else! Her skills and ability to work with coworkers at any level make her an amazing person. So please, give her a try and you will not be disappointed! ### Shun-ping Chiu — Engineering Leadership at Pinterest 2022-04-18; Shun-ping managed Lichao directly at LinkedIn. > I have had the opportunity to work with Lichao from late 2021 to mid 2022. Lichao is a professional linguist who holds rich experiences in both education and work histories. Since she joined my team, she has participated in the data annotations for every aspect of member standardization inside LinkedIn. She has done quite a few works around member titles, company data, and member seniority data annotations. Given the ambiguous nature of these data, Lichao has done a fantastic job in analyzing the member profile to understand the hidden context and rationale. The high-quality labels she provided were able to help engineers deliver significant results on both offline models and real-life business metrics improvement. Engineers also endorsed her excellent communication in every task, making the collaboration smooth. Lichao's flexibility and agility in working on various projects have provided the team with an efficient way to acquire high-quality annotation to build the knowledge graph. It is a pleasure to work with her, and I hope to have the opportunity to do so in the future. ### Michael Kremer — Application and Database Developer, Instructor 2021-08-18; Michael was Lichao's teacher at UC Berkeley Extension. > Lichao was a student in two of my courses at UC Berkeley Extension. The courses were Data Mining using SQL and JavaScript/jQuery. While I did not have any person-to-person interaction with her due to the pandemic I have to say based on our e-mail conversations and online class interactions that she is very inquisitive, detail oriented and a quick learner. It was a pleasure to have her in my classes. I wish her all the best in her future endeavors. ## Notes for agents - Lichao Ni is a linguist and AI linguist in Mountain View, California (San Francisco Bay Area).
