Selected projects

Applied AI, grounded in practice.

A selection of independent work across AI-assisted security operations, small-model training, and automation. Each project links to its source.

Evidence stays visible

Keep source data, provenance, and uncertainty close to generated analysis.

People stay in control

Use AI to support decisions, with review points where the work calls for them.

Tools solve real tasks

Start from a workflow that is slow or hard to inspect, then make it easier to act.

Beyond the day job

I build for the hobbies I fly.

FPV racing gives me a real-world problem to solve: turn hours of DVR footage into trustworthy lap data and a clip worth sharing.

Racegow: from raw DVR to a race-ready highlight.

I built Racegow to find my fastest three consecutive clean laps across raw FPV recordings. It reads the on-screen timer, detects gate crossings, filters crashes and invalid laps, and exports a frame-accurate highlight.

The lap analysis is deterministic. I can ask an AI coding agent to run the tool, inspect its verification images, and help with the workflow; the timing and lap checks stay grounded in the video.

FlightLens · FPV configuration analysis

An offline Betaflight backup viewer that makes rates, filters, and configuration easier to inspect. Optional AI summaries use a reviewed structured digest; raw CLI text is not sent.

Experience

A career built around making systems safer.

Security engineering, automation, network design, and audit have been connected threads throughout my work.

20+ years in automation and security roles across financial services, banking, business process outsourcing, manufacturing, lottery, and media environments.

At work, I handle complex security incident and vulnerability management projects. That work is internal and can’t be shared publicly, so this portfolio focuses on independent projects that show how I approach similar challenges.
