Hey everyone, Harun here again. I’m the 12-year-old solo dev from Anthiyur, India, building an AI coding mentor (KODA) entirely on my POCO C55 Android phone.

Yesterday, I posted about getting my first 5 stranger users. But today, I did something every founder needs to do: **I went on a Supabase Stakeout.**

I opened my `chats`

table to see what people were actually asking my AI when they thought nobody was watching. And I found a session from a user named Nerando.

I recognized the name. He was a Senior Software Engineer from Atlanta, GA who had given my previous Dev.to post a 🦄 Unicorn reaction. But he didn't just click around my app. **He ran a professional, 6-point QA stress test on it.**

Here is exactly how a senior engineer interviews a 12-year-old's app:

**1. The UI Test**

His first message was exactly one of my "Welcome Chips" (clickable starter prompts). He was checking if my UI shortcuts actually triggered the backend correctly. *(Pass ✅)*

**2. The Core Capability Test**

He typed: *"Can you code"*. He didn't want a philosophical answer; he wanted to see if my Groq integration actually generated clean, formatted Python scripts with type hinting. *(Pass ✅)*

**3. The Persona Test**

He asked: *"What are you"*. A lot of AI apps break character here and say "I am a large language model trained by..." KODA stayed in character and replied: "I’m KODA – your friendly coding mentor." *(Pass ✅)*

**4. The Edge-Case Test**

He clicked my 🆘 Panic Button: *"I am confused. Explain simply like I am 5."* He was testing if the formatting breaks when the prompt forces a sudden tone shift. KODA gave a clean, emoji-filled, simple explanation. *(Pass ✅)*

**5. The Boundary Test**

He asked: *"Can you browse"*. This is a classic dev trap. He wanted to see if the AI would hallucinate and lie about having internet access. KODA correctly admitted its limitations. *(Pass ✅)*

**6. The Deep Domain Test**

Finally, he threw a college-level CS concept at it: *"I want to know more about abstraction"*. KODA responded with a masterclass on Procedural vs. Data Abstraction, complete with Python, JS, and Java examples. *(Pass ✅)*

While doing the stakeout, I also noticed something else. Out of my 6 total signups, 3 were fake or ghost emails (like `deneme@deneme.com`

which is Turkish for "test").

My older brother (who is an engineering student and my unofficial Board of Directors) asked me: *"Why keep them?"*

He was right. Fake emails bounce, and high bounce rates destroy your Gmail sender reputation. So I did my first piece of **Data Hygiene**:

`profiles`

table.Now, bots and fake testers can't pollute my database. A clean database of 3 real humans is worth 100x more than a dirty database of 50 ghosts.

Stop guessing what features to build. **Look at your telemetry.**

When I saw another real user (`reversality`

) asking KODA *"how to add PWA manifest"*, I realized I don't need to guess my roadmap. My users are literally typing my to-do list into the chat box.

If you are building a SaaS, go look at your database logs today. What are your users doing when they think you aren't watching?

*(P.S. I sent Nerando a "Sniper Email" letting him know I saw his stress test. Fingers crossed he replies!)*
