Introduction

Hi, I’m Haijun, a Full-Stack Developer | AI Enthusiast | Indie Developer.

It has been a while since I last wrote an article.

I have been genuinely busy recently, mainly pushing forward AI projects inside the company. From requirement breakdown, solution design, frontend and backend development, to Agent workflows, RAG, API integration, and production debugging, I have basically been carrying many parts forward on my own. Fortunately, I have had a reliable teammate fighting alongside me: Codex.

Since last year, my feelings about AI tools have become stronger and stronger: things are changing incredibly fast.
