Code to the Garage: Building a POS with Kotlin and Gemini AI in 3 Days 🚀
As an Android Developer, I’ve always believed that the best way to validate technology is by solving a real-world problem. Last week, I took my culinary venture to the next level by merging my roles as Product Owner and Developer.
🎯 The Challenge: I needed a custom Point of Sale (POS) system to manage sales and daily closings (cash reconciliation). The catch? Time was tight—launch day was just around the corner.
🛠 Stack & Process:
Language: Kotlin, focusing on a responsive UI architecture.
The Accelerator: I integrated Gemini within Android Studio as my "AI Pair Programmer."
Agility: Through multiple iterations, I fine-tuned the business logic and screen adaptability in just 72 hours.
✨ Key Takeaway: Being both the "problem owner" and the "solution architect" helped me realize that efficiency isn't just about writing code; it's about knowing how to iterate with the right tools. AI didn't write the app for me, but it acted as a force multiplier for my ability to interpret operational needs and translate them into stable technical features under pressure.
Entrepreneurship is, at its core, applied engineering.
