I’m the 12-year-old solo dev from Anthiyur, India, building an AI coding mentor (KODA) entirely on my POCO C55 Android phone.\n\nYesterday, 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.**\n\nI opened my `chats`\n\ntable 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.\n\nI 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.**\n\nHere is exactly how a senior engineer interviews a 12-year-old's app:\n\n**1. The UI Test**\n\nHis 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 ✅)*\n\n**2. The Core Capability Test**\n\nHe 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 ✅)*\n\n**3. The Persona Test**\n\nHe 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 ✅)*\n\n**4. The Edge-Case Test**\n\nHe 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 ✅)*\n\n**5. The Boundary Test**\n\nHe 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 ✅)*\n\n**6. The Deep Domain Test**\n\nFinally, 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 ✅)*\n\nWhile doing the stakeout, I also noticed something else. Out of my 6 total signups, 3 were fake or ghost emails (like `deneme@deneme.com`\n\nwhich is Turkish for \"test\").\n\nMy older brother (who is an engineering student and my unofficial Board of Directors) asked me: *\"Why keep them?\"*\n\nHe was right. Fake emails bounce, and high bounce rates destroy your Gmail sender reputation. So I did my first piece of **Data Hygiene**:\n\n`profiles`\n\ntable.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.\n\nStop guessing what features to build. **Look at your telemetry.**\n\nWhen I saw another real user (`reversality`\n\n) 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.\n\nIf you are building a SaaS, go look at your database logs today. What are your users doing when they think you aren't watching?\n\n*(P.S. I sent Nerando a \"Sniper Email\" letting him know I saw his stress test. Fingers crossed he replies!)*\n\nBuilt on a phone in Tamil Nadu.
