Working systems

Don't take my word for it. Use it.

Seven working systems you can open right now, plus the AI and security work behind them. Names and numbers inside are demo data; the logic is real.

AI agents

A fraud-detection system, built as a team of agents.

Reply AI Agent ChallengeMulti-agent

Built for an AI agent competition: a six-stage pipeline where every stage does one job, and the AI stages each use the model that fits, to keep costs down. Raw transactions go in; a ranked, verified list of suspected fraud comes out.

Security

Email security for firms that handle money

Fraudsters send "our bank details have changed" emails in a firm's name. I check the public settings that stop it (SPF, DKIM, DMARC), explain them in plain English, and fix them in stages so genuine mail keeps flowing.

SPF   present
DKIM  missing
DMARC none // anyone can send as this firm

Data

Algorithmic trading research

Automated market-data pipelines, backtesting and statistical testing, built to hold every result to an honest standard before it's trusted.
