ER Terminal
Full-Stack AppA personal equity research and valuation platform built to perform professional-grade fundamental analysis, build DCF models, and track prediction market sentiment.
Overview
Finance students and aspiring analysts often lack accessible tools to practice professional-grade fundamental analysis outside of static Excel spreadsheets. Existing solutions are either prohibitively expensive or too basic, making it hard to gain real-world modeling experience.
I built ER Terminal to solve this. Wrapped in a beautiful navy and gold aesthetic reminiscent of professional finance platforms, it allows users to pull live market data, iterate on interactive DCF models, maintain research notes, and run peer comparables seamlessly in the browser.
