WORKING AI PRODUCTS
Functional prototypes for pricing intelligence and quantitative decision support, built to expose the evidence behind every recommendation.
Built with Next.js, validated data pipelines, transparent calculations, portfolio-hosted APIs, and clearly stated product limits.
Featured product build
MarginLens
A pricing-intelligence workspace that validates sales data, ranks account-level margin shortfalls, exposes the supporting invoices, and tests price-only target scenarios without hiding the assumptions.
Validated input
Rejects incomplete or malformed sales data.
Auditable math
Shows revenue, cost, profit, and source rows.
Scenario testing
Separates benchmark gaps from pricing uplift.
Featured Build
The live widget below runs through this portfolio's API route, so it works on the hosted site without a separate Python server.
Stock Signal Predictor
A live stock-direction experiment that fetches recent market data, computes technical indicators, and returns a transparent next-session signal.
The result includes direction, confidence, a simple time-ordered backtest, RSI, MACD, and last close.
