Contracts, claims, and project controls. Now building Pylonary.

I work in construction contracts and claims.

Most of my work has been around change, notices, closeout, and the project records behind them.

I have worked across infrastructure, industrial, and commercial projects in the U.S. and abroad. I am now building Pylonary from the same document and admin problems I kept seeing on jobs.

How I work

Most of the work comes down to reading the contract carefully and keeping the record straight.

Most of my work has been around contracts, change, claims, and closeout.

I pay attention to what the contract says, what the records show, and where the two stop matching.

That is also what led me to start building Pylonary.

01

Read the contract first

Start with what the contract actually says, not what people assume it says.

02

Keep the record usable

If the records are messy, every later conversation gets harder.

03

Deal with change early

Notice and scope problems are easier to handle early than after months of drift.

04

Cut repetitive admin work

When the same information gets retyped across emails, spreadsheets, and PDFs, the process usually needs fixing.
