I will fix your ai built or vibe coded app and explain it in plain english
Naoshi
About this gig
Built your app with AI, and now it's broken? You're not alone.
AI tools like Lovable and Cursor get you 80% there. The last 20% is where things break: errors you can't read, fixes that break something else, and an AI that keeps going in circles.
I'm a professional engineer with 10+ years of experience, from 24/7 banking systems to startups, and I've spent years taking over code others left behind.
What I fix:
- Errors, crashes, and features that stopped working
- Login, database, and API problems
- Slow pages and messy code that's hard to change
- Security holes AI often leaves behind
How I work:
- I look at your code first and tell you, in plain English, what's actually wrong
- I fix it without rewriting everything
- I explain what I changed, so you can keep building with AI
Why clients like working with me:
- No jargon, no judgment
- Honest: if it's a quick fix, I'll say so
- Fast, friendly chat in English
Not sure where to start? Just message me. Asking is free, and there's no pressure to order. A short description and a screenshot of the error are enough.

I help non-technical business owners build, fix, and understand their apps, without the jargon.
Tell me what you want, even if it's vague like "make it feel better". I'll turn it into something concrete and explain every step.
10+ years as an engineer, from 24/7 banking systems to startups in healthcare, education, and real estate. I take over projects others left half-finished, and I've trained new engineers, so explaining clearly is part of my job.
Stack: Java/Kotlin (Spring Boot), React, Next.js, Laravel, Flutter, AWS, Claude.
Based in Japan. I work by chat and reply fast.
FAQ
Can I just ask before ordering?
Of course. Asking is free and there's no pressure to order. Tell me what's wrong in your own words, and I'll let you know honestly if and how I can help.
I don't understand my own code. Is that OK?
Yes. That's very common with AI-built apps, and explaining it is part of the job.
Will you rewrite my app?
Only if truly necessary, and I'll explain why first. Usually fixing what's there is faster and cheaper.
Can I keep using AI tools after your fix?
Yes. I'll explain the changes so your AI tool (and you) can build on them.
Do you use AI tools?
Yes, openly. I work with Claude every day, even to draft this page. It makes me faster, but every line of code is checked by me.
