Seisuke Yamada

Full-stack Web Developer | Software Engineer

Hi, I'm Seisuke. After majoring in Computer Science and Engineering at university, I have spent the past six years working as a software engineer and full-stack web developer, with experience ranging from large-scale embedded systems to web application development. Throughout my career, I've focused on building efficient, maintainable systems with a user-first approach.

Along the way, I’ve faced various technical challenges as a developer and tackled many issues as a team leader. By working together with my teammates, we’ve overcome these obstacles through persistence and problem-solving. I am eager to bring this resilience and problem-solving skill to help tackle the challenges your team faces!
