Software Development Experiences
Involves writing code and building both web and desktop applications based on the project requirements provided to me. I also focus on enhancing and optimizing system performance, especially since most of the systems assigned to me are existing and have been used for a long time. Because of this, I’ve developed strong skills in analyzing system flow directly through the source code, which allows me to quickly understand and adapt to the processes of any system I work on—whether desktop or web-based.
I have also worked with a development team that follows a methodology similar to the Waterfall model, where all projects and system modifications follow strict policies under project management. Before starting development, project details are provided by the PMO; once development is done, the output is handed over to the QA team for testing, followed by UAT.
One of my notable exprerience is to debug quickly and efficiently, allowing me to identify and resolve system issues or errors whenever needed.
I am highly motivated and proactive when it comes to self-study, especially in exploring modern frameworks and new technologies such as RESTful APIs using ASP.NET Core Web API. I have experience deploying API services publicly using Google Cloud Platform (VM Instance) and Amazon Web Services (EC2 and RDS). Currently, I continue to explore modern technologies and frameworks such as LINQ, Entity Framework, and ASP.NET Core MVC.
