Development Project Achievements
Project example 1
| Job description | Healthcare Industry |
|---|---|
| Responsibility | Basic design, detailed design, implementation, unit testing, integration testing |
| Programming Language | Node.js |
| Framework | express,Vue.js,Nuxt.js,electron |
| Database | PostgreSQL,Azure Kubernetes Service |
| Development Tool | VSCode,GitHub,Kubernetes,Docker |
| Special Note | As part of the software development team, we adopt an agile development methodology with monthly release points. Each team member is responsible for the scheduled improvements planned for that month's release. The team leader organizes the release items each month and assigns them to the development members. Each member then independently investigates and evaluates the overall modification details. After reviewing the plan, they proceed with the necessary changes. |
Project example 2
| Job Description | Electric Power Industry |
|---|---|
| Responsibility | Customer negotiation, basic design, detailed design, implementation, unit testing, integration testing, system testing |
| Programming Language | Java |
| Framework | Spring,Mybatis,thymeleaf |
| Database | Oracle |
| Development Tool | Eclipse,A5M2,SQLDeveloper,Jenkins,TotasSVN,Mattermost,PowerQuery |
| Special Note | Responsible for developing an application for accounting calculations of business sales. This system is client-server-based and includes data integration batches from other functions. The business requirements primarily involve accounting knowledge, so collaboration with accounting experts is necessary to fix bugs and add features to the existing system. In addition to development, project management tasks such as workload management, task tracking, and customer interactions are also handled. Operational tasks, such as correcting fraudulent data, are also managed. Each month, inconsistent data is searched and corrected from approximately 20 million records. To handle this large volume of data, PowerQuery and in-house Java tools are used to ensure data accuracy. |
Project example 3
| Job description | Internal HR system project |
|---|---|
| Responsibility | Basic design, detailed design, implementation, unit testing, integration testing |
| Programming Language | Java, CSS, JavaScript |
| Framework | SpringBoot, Thymeleaf, Bootstrap, jQuery |
| Database | MySQL |
| Development Tool | VSCode, GitHub, Docker |
| Special Note | The internal attendance management system was developed using an agile methodology, incorporating Lean Kanban principles, with each sprint lasting one month. Every morning, stand-up meetings are held to review progress and clarify any uncertainties among the internal development team members to improve the system. Depending on the situation, team members collaborate to resolve issues and challenges. To ensure quality, project reviews are conducted by a separate team, distinct from the internal development team. |

| Special Note | In the batch creation team, we implement agile development with monthly release points. Each member handles development tasks based on the planned releases set for each month. The team leader schedules the projects to be released each month and assigns them to the development members. After this assignment, we conduct a preliminary investigation and review of the overall modification details before proceeding with the updates. Since these are changes to the active system, we test them in a production mirror environment on AWS before applying them to the production servers on AWS. |
