The problem with standard AML tutorials

📊

Same dataset, every time

Kaggle's credit card fraud dataset has been submitted by millions. Hiring managers stop reading at "accuracy: 99.2%."

⚠️

No rule engine

Real compliance teams run weighted rule sets. A classifier alone isn't how transaction monitoring actually works.

📄

No regulatory context

"I tuned a model" means nothing without knowing what BFIU Circular 02/2019 says about structuring thresholds.

🔢

Global false positives

Generic tools misfire constantly on MFS data—round-amount rules that fire on every BDT 500 bazar purchase.

How the toolkit works

Synthetic bKash/Nagad Transactions (10,000+) ↓ Rule Engine—6 BFIU-calibrated rules ┌─────────────────────────────────────────────────────────────┐ │ STRUCTURING ≥3 txns below BDT 10,000 within 24h │ │ VELOCITY ≥5 txns within any 60-min window │ │ DORMANT_SPIKE 30+ day inactive → sudden surge │ │ LATE_NIGHT transactions between 01:00 and 04:00 AM │ │ ROUND_AMOUNT ≥ BDT 50,000 AND ≥5× sender's own median │ │ HIGH_VALUE single transaction above BDT 20,000 │ └─────────────────────────────────────────────────────────────┘ ↓ Composite Risk Score (0–100) → LOW / MEDIUM / HIGH ↓ Threshold Backtesting → tune precision vs. recall ↓ LightGBM ML Layer → reduces false positives by ~40% ↓ SAR Candidates Export → compliance-ready .csv

Who is this for?

ML/Data job seekers

Targeting fintech, fraud, or AML roles? This project gets you a portfolio piece interviewers actually ask about—not just a confusion matrix.

AML analysts learning Python

You know BFIU guidelines. This turns that domain knowledge into working code, end-to-end, without starting from scratch.

Fintech developers

A working POC transaction monitoring engine you can adapt, extend, or demo to compliance stakeholders.

Freelancers & consultants

Pitching banks, MFIs, or compliance vendors in Bangladesh or South Asia? Show them a live demo of domain-calibrated AML capability.

Tech stack

Pure Python. No paid APIs. No cloud setup required. Runs locally on Windows / Mac / Linux.

Python 3.9+ Pandas NumPy LightGBM Scikit-learn Matplotlib Seaborn Jupyter

Common questions

Is this only useful for Bangladesh?

No. The BD calibration (bKash/Nagad thresholds, BDT amounts, and BFIU citations) makes it a great portfolio piece for South Asia. But the architecture—rule engine + baseline-relative thresholds + ML layer—applies to any MFS or digital payments context globally. UPI, JazzCash, M-Pesa, and PayTM all share the same calibration problem.

What Python level do I need?

Intermediate. You should be comfortable with Pandas and Jupyter notebooks. The code is heavily commented and includes a walkthrough notebook. No prior AML/compliance knowledge required—RULE_CALIBRATION. MD explains the regulatory logic.

How do I get the code after buying?

Immediately after purchase, Gumroad sends an email with a GitHub collaborator invitation. You accept it and get access to the private repo. The download link in Gumroad also includes a zip of all notebooks and scripts.

Does the $39 include future updates?

Yes. The roadmap includes a transaction network graph (NetworkX), an SAR PDF generator, and a REST API wrapper. All updates go into the same private repo—you get them automatically as a collaborator.

Ready to build a real AML portfolio project?

One-time payment. Instant GitHub access. All future updates are included.
