I'm a Senior Android Engineer at a FinTech company. I wrote this book because every ML resource I found either explain heavily in math or gave copy-paste code with no understanding.

The book walks through building FinRisk, a credit risk app that runs a trained model on-device in <15ms. The model is 1.8 KB. You train it in Python, convert to TFLite, and integrate into an Android app with Clean Architecture + Hilt + Compose.

Happy to answer questions about on-device inference, TFLite, or the Android integration.
