Software Engineer  •  Velodash ( 沛司科技股份有限公司 )

Apr 2019 - Oct 2023  |  Taipei, Taiwan

In this company, I am responsible for the development of both mobile apps and webpages. I worked on two major projects. The first one is the B2B-side application called Staff (Web/Android/iOS), and the second is the B2C-side project called Velodash (Web/Android/iOS). Due to the similarity in functionality between the web and app, to reuse the same codebase, both are developed using Dart. The difference lies in the web version using Dart React, while the app utilizes Flutter. I also place emphasis on the separation of business logic and UI design.

The scope of the project covered various features such as adding new route and events, exploring events and routes created by others, viewing live events, personal profiles, inboxes, user communication, disaster reporting, and more. The following are some key aspects:

• Utilized MobX as a state manager and Drift as a local database. WebSocket was employed to ensure synchronization between local data and server data.
• In 2020, due to the immaturity of Flutter Web, the web version was developed using the Dart version of React.
• While web and app share common business logic, there are still some differences in implementation (e.g., which API to use). Therefore, I utilize get_it and injectable as Dependency Injection tools to facilitate easier implementation swapping.
• On the app side, when certain native functionalities lacked plugin support, communication with the native platform was established using Method Channel, for example, with flutter_barometer.
• On the web side, since Dart React developers do not primarily focus on static typing, I created a custom tool called type_react . It uses code generation technology to automatically parse class field names and convert them into corresponding React objects.
• Docker was employed for deploying the web version.

Skills Summary: Dart, Flutter, react, mobx, drift, event_bus, method channel, code generation, Docker

GodotSharpKit ( C# Source Generator ) • Jun 2023 - Now

Nuget / Github / Motivation behind the production ( 製作緣由 )

A C# Source Generator designed for the Godot game engine. The motivation behind this project stems from the engine's issues with C# support, often requiring extensive boilerplate code. To address this, a new project was initiated to automate code generation. The main functionalities of this project include:

• Generating OnReady code.
• Generating code for resource locations.
• Generating code for communication with GDScript.
• When producing code, utilizing "record" to carry metadata, enhancing the efficiency of the Source Generator. This helps prevent redundant code generation resulting from edits to the source code.

Skills Summary: C#, Godot, Source Generator
