02 / Applied AI / Lawlab
Helping property lawyers
review documents faster.
Buying a property involves a lot of paperwork. I built an AI assistant that brings the important information together, checks its output and helps a person review it.

Approximate review times from my 2024 Lawlab work, as reported in my CV. The system supports a human reviewer’s decision.
The product todayExplore BuySecureThe problem
Important details were spread across lengthy property documents. Finding and reviewing them took time.
What I built
In a small engineering team, I built the interface, backend, AI workflow and deployment — connecting document reading, information extraction and checks into one review system.
Why it mattered
Reviewers could get to the relevant information much sooner, with validation and human review built into the workflow.
The engineering behind it
OCR and PDF interpretation, structured extraction, document retrieval and model comparison, supported by a full-stack application and deployment. The work focused on reducing errors and giving reviewers information they could check.
A simpler way to explain it
Find the details by hand.
Work through the documents, collect the relevant information and prepare it for review.

Each document is another place to look.
Start with the information.
The assistant reads the documents and brings relevant details into a structured view for a person to check.

Real problems.
Real environments.
From radio networks and field hardware to production AI. I work across the whole journey: understanding the problem, building the product, and making it work in the real world.

QUESTGIVER / BUILT FOR YOUR POCKETA little window into my workshop.
05 / Hello from Melbourne
Engineer by trade.
Curious by default.
I’m happiest moving between a difficult problem and a working prototype, then doing the less glamorous work that makes it useful to someone else.
My route here has taken me from Ireland to New Zealand to Australia, through radio systems, mapping, mixed reality and AI. Outside the build, it’s astronomy, sci-fi and strategy games. There’s usually another idea on the go.
