No bloated features.</p> <p>Just a fast way to:</p> <ul> <li>Collect emails</li> <li>Measure interest</li> <li>Validate ideas</li> </ul> <h2> Building with AI </h2> <p>This is where things got interesting.</p> <p>I used AI (mainly Claude) as my coding partner.</p> <p>Instead of writing everything from scratch, I:</p> <ul> <li>Generated components</li> <li>Fixed bugs faster</li> <li>Structured the app quickly</li> </ul> <p>It felt like having a senior developer helping me 24/7.</p> <h2> Tech Stack </h2> <p>I kept it simple and fast:</p> <ul> <li>Next.js (frontend + backend)</li> <li>Supabase (auth + database)</li> <li>Vercel (deployment)</li> <li>Claude AI (development)</li> </ul> <p>Total cost: $0</p> <h2> What I Built </h2> <p>The result was WaitlistPro.</p> <p>A simple tool where you can:</p> <ul> <li>Create a waitlist in under 60 seconds</li> <li>Share a public signup page</li> <li>Track subscribers</li> <li>Add referral mechanics</li> <li>Export your data</li> </ul> <p>👉 <a href="https://waitlistpro.com.tr" rel="noopener noreferrer">https://waitlistpro.com.tr</a></p> <h2> Key Lessons </h2> <ol> <li><p>Speed matters more than perfection<br><br> If you wait too long, you lose momentum.</p></li> <li><p>Validation is everything<br><br> Don’t build first — validate first.</p></li> <li><p>AI is a force multiplier<br><br> You can build 10x faster if you use it right.</p></li> </ol> <h2> Final Thoughts </h2> <p>This wasn’t just a coding experiment.</p> <p>It completely changed how I approach building products.</p> <p>Now I always validate before I build.</p> <p>If you’re thinking about starting a SaaS — start small, validate fast, and use AI to move quicker.</p> <p>If you want to try the tool I built:</p> <p>👉 <a href="https://waitlistpro.com.tr" rel="noopener noreferrer">https://waitlistpro.com.tr</a></p> <p>Would love your feedback 🙌_****</p> webdev ai beginners learning
