自傳

     我的名字是蔡彥臣，目前居住於新北市。我畢業於台灣大學機械研究所，就讀研究所期間曾將論文投稿至米蘭IFAC研討會，並於會中以口說形式發表。


     我目前在NextDrive擔任iOS工程師，負責開發與維護Ecogenie，並運用IoT相關技術(如MQTT等)做硬體與APP的整合，同時串接雲端資料(如會員系統等)。在公司初期，我負責開發初版SDK：將Ecogenie軟體核心封裝出來，預計供第三方廠商使用的framework。隨後，我參與APP改版計畫，將整個APP除了部分底層的功能之外，完全翻新成新的頁面與流程，並在品質逐漸穩定之後，作效能調整。除此之外，在APP新功能推出之前，也必須與UI/UX設計師討論相關頁面的設計，從中學習到許多使用者體驗的設計概念。


     除了iOS軟體開發的技能之外，過去的工作經驗讓我同時擁有韌體開發與系統整合的能力。


     在旺矽科技任職期間，我隸屬於LED測試系統部，負責以C#開發並維護報表分析軟體，並依照不同客戶需求做客製化軟體功能，這其中包含UI、演算法與版本管控；同時，我還負責熱阻抗量測系統的開發，其中包含DAQ量測卡與公司軟體的整合。


     結束了旺矽科技的工作後，我加入了納智捷汽車研發中心：華創車電。我就職於電動工程部，是LUXGEN S3EV(U5)電動車開發計畫的成員之一。在剛就職的前四個月，我獨立開發出BDU系統韌體並持續穩定運行。隨後，我被賦予BMS韌體開發任務，在開發期間，我在BMS系統上實現 J1772與GBDC充電通訊協定，同時將BMS系統整合至電動車上，並將BMS與其他動力系統整合至可穩定運行。

     

     身為一位軟體開發者，我具備了從產品的底層韌體到上層應用軟體的相關知識，這讓我更容易理解產品的技術全貌。藉由過去的軟韌體開發經驗，讓我在目前IoT領域的整合應用，可以用更多元的視野分析問題並提出意見。在現今這個講求跨領域技術的時代，我希望能利用自身的技術背景，開發出更多不同領域的iOS應用。

Autobiography

    My name is Yen-Chen Tsai, living in New Taipei city, Taiwan. I graduated from National Taiwan University, majored in mechanical engineering, master degree of engineering.


     I have 5 years experience in develop iOS app. Now, I am a Sr. iOS developer in 17 LIVE. My job duty is developing new features in 17 LIVE APP. 17 LIVE is a live streaming app, user can choose the streamer from hot page and join the stream room. In the stream room, streamer and viewer have lot of interactive by send gift, group stream...etc. 


     As a Sr. iOS developer, I play as a role like tech lead. I have to analyzed the complexity of new features and give suggestions to PM. I also have to break down the tasks to iOS members, giving the opinions for new structure design, and implement the most complicated part by myself.

        

     As a programer, I have experience and knowledge for developing from firmware layer to application layer in a product, which means I can analysis problems with pluralistic attitude. Nowadays, it is the age of cross - cutting, I believe that I can develop various iOS application with my technology background.

     除了iOS軟體開發的技能之外，過去的工作經驗讓我同時擁有韌體開發與系統整合的能力。


     在旺矽科技任職期間，我隸屬於LED測試系統部，負責以C#開發並維護報表分析軟體，並依照不同客戶需求做客製化軟體功能，這其中包含UI、演算法與版本管控；同時，我還負責熱阻抗量測系統的開發，其中包含DAQ量測卡與公司軟體的整合。


     結束了旺矽科技的工作後，我加入了納智捷汽車研發中心：華創車電。我就職於電動工程部，是LUXGEN S3EV(U5)電動車開發計畫的成員之一。在剛就職的前四個月，我獨立開發出BDU系統韌體並持續穩定運行。隨後，我被賦予BMS韌體開發任務，在開發期間，我在BMS系統上實現 J1772與GBDC充電通訊協定，同時將BMS系統整合至電動車上，並將BMS與其他動力系統整合至可穩定運行。

     

     身為一位軟體開發者，我具備了從產品的底層韌體到上層應用軟體的相關知識，這讓我更容易理解產品的技術全貌。藉由過去的軟韌體開發經驗，讓我在目前IoT領域的整合應用，可以用更多元的視野分析問題並提出意見。在現今這個講求跨領域技術的時代，我希望能利用自身的技術背景，開發出更多不同領域的iOS應用。

Autobiography

    My name is Yen-Chen Tsai, living in New Taipei city, Taiwan. I graduated from National Taiwan University, majored in mechanical engineering, master degree of engineering.


     I have 5 years experience in develop iOS app. Now, I am a Sr. iOS developer in 17 LIVE. My job duty is developing new features in 17 LIVE APP. 17 LIVE is a live streaming app, user can choose the streamer from hot page and join the stream room. In the stream room, streamer and viewer have lot of interactive by send gift, group stream...etc. 


     As a Sr. iOS developer, I play as a role like tech lead. I have to analyzed the complexity of new features and give suggestions to PM. I also have to break down the tasks to iOS members, giving the opinions for new structure design, and implement the most complicated part by myself.

        

     As a programer, I have experience and knowledge for developing from firmware layer to application layer in a product, which means I can analysis problems with pluralistic attitude. Nowadays, it is the age of cross - cutting, I believe that I can develop various iOS application with my technology background.
