What it is

A self-directed full-stack portfolio application covering stocks, funds, and cryptocurrencies, handling time-series storage and continuous position valuation, and using the Alpha Vantage API to ingest real-time market data over REST.

Built unprompted, before any of the finance-adjacent competition work — it is where the interest in financial systems actually started rather than something assembled to demonstrate it.

The Portfolio Tracker interface: a table of three holdings — cash, Apple Inc, and Bitcoin — with quantity, price and value columns, a pie chart of their relative weights below it, a running total of $16,761.93, and an add-asset form alongside.
