Harlan Chang

Senior Backend Engineer

  Taiwan


More than 12 years of software development experience. Skilled in effective high traffic online service, OLTP service, Software as a Service development. Good at cross-funcitonal cooperation and communication.
In my present position, I am a Senior Backend Engineer in KKStream Limited. Responsible for maintain, performance tuning, system analysis and design of OTT service.


1985 年生,畢業於高雄第一科技大學資管系,個性風趣、善於溝通。興趣是打籃球、料理、品酒、偶爾彈吉他。過去喜歡做一些 side project 也有點為 socket 程式設計產生著迷,喜歡研究 WEB 程式設計中較 low level 的原理並實現。我熱愛 coding 對團隊管理也有興趣。

我善於與不同部門進行溝通協調,並協同成員達成任務。在團隊中較常負責系統架構規劃開發與新技術可行性調查等工作。

PHP 開發資歷約莫 13 年,從業界前後端尚未分離的全端工程師一直到現今前端框架成熟的世代,進而轉向更深入的後端研究。開發更適合自己的輕量高效框架 CONPOZ 並更易於配合現代 PHP 的工具 composer 整合使用 (https://github.com/hikaruocean/conpoz)。借著過去兩年多來與 C++ Game Server Engineer 的合作,將更紮實的程式底層經驗運用在 WEB 開發上。

DB 常使用 Mysql/Mariadb 包含規劃 Schema,Sql 語法最佳化,協同 Replication 架構規劃,撰寫自動讀寫分離 library (包含 transaction 與 lock 語法時自動切換至 Master DB)。
