Detail-oriented estimator who delivers accurate costs and efficient project outcomes.
What I'm looking for
I’m a detail-oriented estimator with a life-long background in the industry, focused on producing accurate cost estimates and keeping projects efficient and competitive. I bring practical knowledge of materials, methods, and project workflows to every job.
In my current estimator role, I use Bluebeam daily to produce accurate estimates, including estimating a whole house from dirt to shingles. I communicate with designers, builders, subs, and suppliers regularly, and I stay hands-on with tools like Excel and Word to keep estimates and documentation tight.
Before estimating, I built strong leadership and field experience as a Site Supervisor and Construction Assistant, overseeing daily operations, managing staff and volunteers, and ensuring work meets up-to-date quality standards and code compliance. I’m comfortable coordinating teams and subcontractors, reviewing invoices weekly, and executing framing, plumbing, and electrical work when needed.
