About Me
My Journey
Full Stack Software Engineer with 3+ years of experience building scalable web applications and APIs, with a strong foundation in the TypeScript ecosystem. I work across frontend and backend using Angular, Node.js, Express, and relational databases, with a particular focus on clean API design, efficient data modeling, and maintainable system architecture.
I prioritize well-structured solutions that balance technical rigor with real-world constraints. My work is guided by clean and hexagonal architecture principles, aiming for modularity, clarity, and long-term flexibility. I care deeply about code quality, accessibility standards (WCAG), and building systems that remain understandable and evolvable over time.
I strongly believe in continuous improvement (Kaizen) and enjoy deepening my backend expertise by exploring system design, databases, and modern backend frameworks such as NestJS. I value learning not as a trend-driven exercise, but as a way to sharpen engineering judgment.
My development philosophy is inspired by Wabi-sabi (侘寂): embracing simplicity, imperfection, and gradual refinement. In practice, this means building software that is practical, resilient, and thoughtfully designed—focused on long-term value rather than short-lived perfection.
Personal Philosophy
The best code is like a Japanese garden – carefully crafted, balanced, and appears simple despite the complex thought behind it.
I believe in the Japanese concept of 'Kaizen' (改善) - continuous improvement. Each project is an opportunity to refine my craft and expand my knowledge.

Featured Projects
A selection of projects that showcase my technical skills, problem-solving abilities, and passion for creating impactful solutions.
Hyōsei – Academic Evaluation Platform
Full StackHyōsei is a full stack web platform designed to manage evaluation workflows for academic events such as science fairs, conferences, and university project assessments. It enables organizers to define custom evaluation scales, dynamic forms, and multi-role review flows. The system was built following clean and modular architectural principles, prioritizing scalability, maintainability, and clear business logic boundaries. It includes role-based access control, optimized relational data modeling, and well-structured REST API design.
Ishin – Personal Medical Record Application
Health-Tech / Full StackIshin is a mobile-first health-tech application designed to allow users to securely manage personal medical records. It supports medication tracking, allergy records, chronic conditions, vital signs, medical history, and appointment management with notes. The system includes an emergency profile accessible via QR code to provide rapid access to critical information. The frontend is built with Next.js, while the backend is currently in architectural planning, considering a secure design with PostgreSQL, JWT-based authentication, and encryption of sensitive medical data to ensure privacy and data protection.
Kōbun – PDF Splitting Utility
Desktop Utility / ToolsKōbun is a desktop utility built with Python and a Tkinter-based graphical interface, designed to split PDF documents efficiently. It supports custom page range selection, input validation, and structured output file generation. The document-processing logic is decoupled from the UI layer to ensure maintainability and clarity. The visual design is inspired by the Cinnamon desktop environment, focusing on simplicity and usability. The project is currently under iterative improvement, with plans for cross-platform packaging and expanded functionality.
