Yusuke Hayashi

I love building useful things with code, and I enjoy long rides on my road bike.

For consulting and project inquiries, see haya.company (AI implementation support & workflow improvement, end-to-end from scoping to production rollout).

Things I love

• Shipping products end-to-end (backend / frontend / infra)
• Improving developer experience (tooling, automation, documentation)
• Designing scalable and maintainable systems (often on AWS)
• Learning fast and sharing what I learn
