Fortuna
AI-powered personal finance & wealth mentor
A production-ready, cross-platform personal finance app with a voice-first UX, real-time AI coaching on spending and goals, and a distributed backend powering timezone-aware financial pipelines.
The Problem
Most budgeting apps show charts. Very few help people think clearly about money in a structured, long-term way. I wanted a system that could answer: "What does my lifestyle look like as a graph of entities, cashflows, and goals—and where do I leak money?"
What I Built
- Cross-platform React Native (iOS & Android, non-Expo) with voice-first UX, WebSocket chat, ElevenLabs TTS, and biometric auth
- FastAPI + PostgreSQL backend with JWT/MFA, row-level security, device-bound sessions, and deep linking
- Celery + Redis distributed task system for timezone-aware financial pipelines and APNS push delivery
- AI coaching engine on Anthropic Claude with dual-channel reasoning, tool-forced outputs, PII sanitization, and circuit breaker pattern
