AML & Fraud Detection Toolkit

Live · Gumroad

A 6-rule BFIU-calibrated transaction monitoring engine plus a LightGBM ML layer for bKash/Nagad-style MFS data. Includes a calibration doc explaining why global AML tools misfire on South Asian mobile-money patterns.

Pipeline: rules → risk score → ML → SAR export

Triageist — ER Triage Prediction

Kaggle Hackathon 2026

Random Forest model predicting Emergency Severity Index (1–5) from patient vitals, built for a $10K-prize Kaggle hackathon. Documents its own limitations openly — synthetic data, class imbalance — instead of overselling the result.

Dataset: 5,000 synthetic patient records

DA Freelance Toolkit

Live · built with Claude API

An AI-powered growth engine for data-analytics freelancers: proposal generator, gig-SEO optimizer, rate calculator, and a client pipeline board — API key kept server-side, never exposed to the browser.
