During his time at Xiaoi, Andy was part of a three-person team responsible for the overhaul of a Solr-based search engine, a key component of the company's knowledge base software. He improved the average search speed by 12% by implementing new methods to existing search components such as hit highlighting and revised the querying logic to improve search result relevancy. Andy also rewrote the entire search query-building code using Spring Data Solr, which improved code structure and made it easier to edit the querying logic and add new features to the search engine. Additionally, he implemented new features such as related searches and advanced search and set up a log monitoring and analytics dashboard for the knowledge base software using the ELK Stack. Before joining Coinbase, Andy worked as a Software Engineer at Uber, where he was a full-stack engineer on the Marketplace Data Foundation team. His work involved developing Dimrunner, a full-stack service for end-to-end spark job management, and Hexographer, Uber's geo-spatial indexing system.
