Top SchoolStar Poon is a Data Engineer with 11 years’ experience building and operating large-scale data platforms across Asia, currently based in Tokyo and working at LY Corporation. He has deep hands-on expertise with Trino/Presto, having contributed performance-focused core enhancements to the Trino engine and operated massive SQL-on-Hadoop clusters at Yahoo! JAPAN. His background spans end-to-end big data pipelines—Spark, Kafka, Cassandra—and production networked systems, including implementing file-based network topology for efficient resource allocation. Comfortable in both performance engineering and open-source collaboration, he combines practical cluster operation with code-level fixes that improve SQL semantics and query analysis. Notably, his contributions to a high-profile project like Trino signal strong distributed systems instincts beyond routine platform maintenance.
