At 安图特（北京）科技有限公司, I review database technical plans, troubleshoot complex database issues, and advise financial clients on architecture and domestic database selection. I also develop delivery standards and report templates for a DBA team.
At 金蝶软件（中国）集团有限公司, I managed DBA and operations teams and improved database operations across ERP environments. I helped adapt ERP products to domestic databases and supported security certifications including 等保三, SOC, and ISO27001.
Earlier, at 斗鱼网络科技有限公司, I formed a DBA team and worked on database optimization and architecture changes; database I/O load fell by 85%, and availability rose from 99.9% to 99.99%. At 世纪龙信息网络有限责任公司, I contributed to moving an account system from Oracle to a distributed MySQL cluster.
