Practical AI Technology In-Depth Coverage
Heeviz is a tech blog on AI, automation, and software development. I run always-on personal servers and automation pipelines for real, and document what comes out of them — successes and failures (postmortems) alike.
Mission
Stories from operations, not demos. How AI agents and automation actually run, how they quietly break, and how they get fixed — including incident write-ups and dead ends, so practitioners can put the lessons to work immediately.
Areas of Expertise
AI & LLM Applications
Hands-on lessons from building and operating LLM-based agents and automation pipelines with Claude, GPT, and Gemini
DevOps & Postmortems
Incident recoveries, dead ends, and design fixes from systems in real operation — discovery, root cause, fix, and lessons
Full-Stack & Mobile Development
Web development with Next.js, React, TypeScript, and Python, plus building and shipping personal Android apps
Automation & Data Pipelines
Auto-publishing content, collecting and analyzing data — designing one-person automation systems run by cron jobs and bots
About the Author
Heeviz is a solo tech blog operated by a Seoul-based software engineer. With over 10 years of development experience, I build and run AI agents, automation pipelines, and web/mobile apps around the clock — and turn that process into content.
