Hi, I'm Isamu Matsuyama

Web Systems Developer building practical full-stack systems from real operational needs.

About me

I have a background in recruitment, multilingual support, and business operations in Japan. Over the past several years, I have also been developing web systems to solve day-to-day operational problems more effectively.

My work focuses on internal tools, workflow improvement, and practical full-stack web development.

Current focus

  • Full-stack development
  • Internal systems
  • Business process improvement
  • AI-assisted development
  • Practical tools built from real operational needs

Tech stack

  • Frontend: SvelteKit, JavaScript, TypeScript, Tailwind CSS
  • Backend: FastAPI, Django REST Framework, Python
  • Database: PostgreSQL, MariaDB, Firebase
  • Infrastructure: Nginx, Gunicorn, DigitalOcean, Oracle Cloud
  • Tools: Git, GitHub, OpenSpec, Ollama

Note on professional work

In my current role, I have been involved in developing internal tools and workflow-oriented systems for operational improvement. Since these systems are company property, their source code is not published here. This profile focuses on public projects, technical experiments, and independent work.

Interests

  • Internal systems and DX
  • Workflow automation
  • AI-assisted engineering
  • Practical web applications
  • Multilingual business-oriented systems
