I am highly responsible and have a calm personality. I have worked as a system engineer, mainly using C#, Vue, and AWS, with a particular strength in development using C# (.NET). I have been involved in the development of web systems and Windows applications. Examples include insurance reservation systems, tax filing accounting systems, volunteer activity systems, e-commerce systems, and client-server type WMS systems.I have consistently handled all phases from requirements definition to design, construction, testing, maintenance, and operation. In my fifth year of employment, I mainly experienced project leader duties. Rather than simply accepting existing designs and customer requests, I provided project manufacturing tailored to each customer by considering their latent demands and desired future state. My major achievement includes serving as PMO for a large-scale automobile insurance project.I also have experience in system construction and maintenance work using AWS. I have obtained PMP certification and have experience in training and managing new employees, demonstrating strong communication skills. My Japanese language proficiency is at a business level.
