Tatsu has experience in the IT industry since 1988 starting as a COBOL programmer for mainframe computers. After that, he worked as a support, PS, and pre-sales engineer for Sybase, Excite@Home, RiverSoft, Interwoven, Dell, SupportSoft, CA, Webroot, Citrix, and SOASTA before he joined Splunk. Those provided Tatsu the opportunities to learn deeply about RDBMS, Networks, Hardware, APM, Security, and 4G/5G Mobile Communication, which is helping him truly understand the requirements of Splunk use cases.
