Spire Financial Modeling Tool, https://spire-pi.vercel.app
Built and deployed a five-module finance platform in TypeScript and React covering portfolio risk, company valuation, M&A analysis, stock screening, and personal finance tracking. Implemented DCF, LBO, and M&A accretion/dilution models from the underlying financial formulas, drawing company data from SEC EDGAR through a weekly automated pipeline. Developed a Monte Carlo engine running thousands of simulated trials to model the full range of portfolio outcomes, weighing downside risk against expected return. Designed a SQL-based stock screener ranking 189 companies against sector medians, verifying results against each company's 10-K filing.
