Android personal-finance app that shows its working — every figure cites the rule and version that produced it. Fully offline and encrypted on the device, with no account and no server. Rupees are integer paise end to end, and a custom lint rule fails the build if a floating-point type ever holds an amount.
Every figure cites the rule id and version behind it, so an answer given months ago stays reproducible
Exact paise arithmetic, enforced by a custom Android Lint rule that fails the build rather than a reviewer who must spot it
Receipt OCR and bank-SMS parsing run on the device, behind per-feature consent that is off by default and revocable

I have been a Software Developer at CortexCraft.ai since January 2026, after several years of freelance web and app work. I write backends in Spring Boot, Express.js and FastAPI, and connect them to LLMs, speech-to-text, text-to-speech and tool-calling agents.
