Software Craftsmanship: Design patterns, DDD, clean architecture, and quality practices

About Nozomi Koborinai

Nozomi Koborinai speaking at a tech conference

I graduated from an IT technical college in March 2019, where I built my foundation in object-oriented programming with Java.

Over my 6 years of experience, the first four were spent developing electronic medical record systems using C#, teaching at Flutter University (Japan’s Flutter engineering community), and co-authoring books on Flutter design patterns. Currently, I work at a Google Cloud Partner company in Japan, specializing in Serverless Application development (Google Cloud, Firebase, DevOps, IaC, Identifier). My deep interest in software architecture has made me proficient in ensuring quality through DDD and clean architecture principles.

Recognition & Community

Google Cloud Partner Top Engineer (Serverless App Development) 2025 & 2026 - Japan-exclusive award program
Contributor to genkit-ai organization, including developing the Dart client for Genkit
Author and maintainer of Mastering Genkit book series
Speaker at Google I/O Extended Tokyo and GDG DevFest
Former instructor and current 1-on-1 mentor at Flutter University

I believe that promoting good products is essential for energizing developer communities. Driven by my passion for great products and developer communities, I feel a strong mission to spread their value worldwide. Deeply impressed by Firebase’s exceptional developer experience, I explored Genkit and was captivated by its innovative approach.

Beyond Code

When I’m not coding, I enjoy:

🎸 Music: Guitar playing and beat-making
📚 Reading: Exploring new ideas and perspectives
🌱 Open Source: Contributing to projects that improve developer experience

Improving developer experience is at the heart of my work and brings me the greatest joy.

Why koborin.ai?

The name koborin.ai carries a meaningful play on words:

koborinai - My family name, representing my personal identity
koborin.ai - The domain combining my nickname with the .ai TLD, symbolizing the intersection of personal journey and technology
AI Explorer - Reflecting my dedication to exploring and contributing to AI-powered products and frameworks like Genkit

This dual meaning captures both who I am and what I’m passionate about: bridging traditional software craftsmanship with cutting-edge AI technologies, always with a focus on exceptional developer experience.

Feel free to explore this garden, and I hope you find something valuable here. This space is always growing, just like the technologies and practices we work with every day.
