About

Welcome to gfish.online, a tech blog dedicated to AI engineering and developer productivity. I am gfish, an AI full-stack engineer with over 6 years of software development experience. My background is rooted in Java backend development, with deep expertise in building enterprise-grade microservice architectures using Spring Boot and Spring Cloud. In recent years, I have shifted my focus toward AI engineering, exploring how artificial intelligence can be effectively applied in real-world development scenarios.

About This Site

gfish.online is my personal tech blog where I share hands-on experience and in-depth insights on AI tools, developer productivity, and backend engineering. All content published here is based on real project experience and is written to be practical, verifiable, and immediately actionable.

Whether you are a junior developer just starting out or a seasoned engineer looking to stay current, you will find useful technical references here. I believe great technical writing should be concise, practical, and substantive — principles that guide every article published on this site.

Focus Areas

The content on this site revolves around three core themes:

  • AI Tools and Practices — In-depth guides on cutting-edge AI development tools such as Claude Code, Cursor, and the MCP protocol, covering usage tips, best practices, and workflow integration strategies to help developers achieve a tenfold boost in coding productivity.
  • Developer Productivity — Sharing end-to-end efficiency optimization methods, from development environment setup to continuous deployment, including toolchain configuration, automated workflow design, and practical tips accumulated from daily development work.
  • Backend Engineering — Covering core backend topics including Java and Spring Boot microservice architecture design, performance tuning, and distributed systems practices, distilled from hands-on experience in production environments.

Our Mission

The mission of this site is to help developers work smarter. AI is fundamentally transforming every aspect of software development, but the real value lies not in blindly chasing new technologies. Instead, it comes from combining AI capabilities with solid engineering practices to find practical paths that genuinely improve productivity. Through continuous sharing of actionable technical content, I aim to help more developers stay competitive and build better products in the AI era.

About the Author

I am an AI full-stack engineer with over 6 years of software development experience. My early career focused on Java backend development, where I built extensive hands-on expertise in Spring Boot and Spring Cloud microservice architectures. As large language model technology advanced rapidly, I transitioned into the AI engineering domain. My current focus areas include research and application of AI-assisted development tools, engineering practices for LLM-based applications, and building developer productivity toolchains.

In addition to maintaining this blog, I also maintain open-source projects and tools on GitHub. You can follow my open-source work on GitHub, and subscribe to the WeChat Official Account "FishTech Notes" for the latest article updates.
