Autobiography
我是一名喜歡學習新技術、挑戰不同領域的人，目前在Morrison Express專注於全端開發，積極參與物流和倉儲工具Web程式的開發，以提高倉庫人員的作業效率。
在資拓宏宇參與了M3專案，在這過程中學習了spring framework, hibernate等框架的使用，建立了Web開發架構的基礎。在專案上線後，AP遇到記憶體不足導致crash問題，之後經由分析把造成memory leak的物件改成Sington模式解決了這個問題，經由這次事件知道了Design Pattern的重要性。
在之後參與了BankWiz產品開發，這是一套可以讓使用者容易的開發SOA Application的工具。而開發產品與開發專案的思維不同，需要更注重軟體架構的可擴充性，以及如何穩定的交付給客戶，因此，我為這套產品設計了一套框架，使其他同事減少開發新功能的學習成本，事後發展成其他產品也可套用這框架。在SOA Mapping的部分，我設計了演算法使原本需要數秒才能mapping到服務進而優化為數毫秒。此外，我也在團隊中積極導入CI/CD流程，這期間增強了許多有關IaC的知識以及自動化腳本撰寫等技能。
之後在趨勢時主要做的是DevOps的工作，在工作的過程中熟悉了AWS/Azure的使用，由於趨勢是一間資安公司，特別重視資安議題，這加強了我之後開發軟體更注重這一塊。為了從log分析可疑行為，我使用了Kafka、Logstash、Elasticsearch,來建立一套收log系統，更使用pandas去處理分析log這塊，以及規範了如何與其他team分享log。

Autobiography
I am Ian, who enjoys learning new technologies and taking on challenges in different domains. Currently, I am at Morrison Express, focusing on full-stack development, and actively involved in developing web applications for logistics and warehouse tools to improve warehouse CS/OP work efficiency.
While at IISI, I was involved in the M3 project, where I became familiar frameworks like Spring and Hibernate. After the project went live, a memory leak issue occurred in the application. After analyzing the issue, we used Singleton Pattern to solve the issue. After this incident, I realized the importance of design patterns.
Subsequently, I participated in BankWiz development, which was a tool designed to make it easy for users to develop SOA (Service-Oriented Architecture) applications. Developing a product requires a different mindset compared to project development. It requires greater attention to the scalability of software architecture and ensuring stable delivery to customers. So, I designed a framework that reduced the time required for adding new features. Over time, this framework apply to other products as well. In the context of SOA mapping, I designed algorithms that improved the mapping process from taking seconds to mere milliseconds. Additionally, I proactively introduced CI/CD processes within the team, which enhanced my knowledge of IaC (Infrastructure as Code) and honed my skills in writing automation scripts.
Later, during my time at TrendMicro, I am a DevOps engineer. In the course of my work, I became well-versed in the use of AWS and Azure. Given that TrendMicro is a cybersecurity company, there was a particular emphasis on security concerns, which further reinforced my focus on security aspects in software development. To analyze suspicious behavior in the logs, I implemented a log collection system using Kafka, Logstash, and Elasticsearch. Additionally, I utilized Pandas for log analysis. I also established guidelines for sharing logs with other teams.
