“System design expert with strong coding abilities. Tongxu worked on my team for more than a year. During this time, she took on some of the most ambiguous problem statements, like figuring out a common pattern of API usage for externally exposed directories, and proposing changes to make them future proof, figuring out the requirements for a feature to allow users to request for more functionality from their admin etc. These problems needed her to understand the domain completely, figure out areas for improvement, and provide migration pathways that get us to where we need to be, without disrupting usage for end-users. Tongxu came through every time, and was able to deliver a fully polished product, with all bells and whistles. In some of these projects, due to bandwidth constraints, Tongxu had to act as our UX and Product Manager, and performed both the tasks admirably. Tongxu brings strong coding abilities to the table, to compliment her deep design skills. Oftentimes, she had to step into a project that was flagging to provide additional support, and never failed to deliver. The one attribute of hers that shines through is her endless patience, in the way she approaches a vague problem, in the way she engages in collaboration with cross-functional teams, and in the way she reaches the finish line in development. She brings a sense of calm to the team around her, and has a positive influence on moral and throughput. She'd be a great addition to any team that has system design requirements, and also need someone to take it through to execution.”
