InvestTracker — Personal Wealth & Portfolio Analytics Platform
Problem: No existing tool could consolidate Polish investment accounts (IKE, IKZE, OIPE, Finax) together with foreign stocks, ETFs, crypto, and precious metals into a single accurate dashboard.
Rozwiązanie: Built a full-stack portfolio tracker from scratch — FastAPI backend with FIFO cost basis calculations, three market data providers, multi-currency reconciliation, and a React dashboard that shows everything in one place.
Live production app at investtracker.eu. The only tool that correctly consolidates Finax transactions with Polish tax-advantaged accounts and international holdings into one accurate P&L view. Active development continues — potential SaaS release planned.
