What I'm looking for

I'm looking for opportunities to lead estimating, cost-control, tender, and project-controls work for construction, infrastructure, or public works projects, while improving accuracy and speed through stronger processes and new estimating tools.

I've led cost estimates, bid proposals, and unit-price database management for Art Arquitectura Temporal's portfolio of up to 40 concurrent projects, representing approximately USD 8.5M annually. Through root-cause analysis, I reduced cost variance on critical items from 30% to 10%.

At Angeles Solest, I built the estimating and cost-control area from the ground up, standardizing quantity take-offs, unit-price analysis, and pricing databases. The new process cut budget preparation time by more than 50% while supporting competitive, profitable bids.

My experience spans residential buildings, road infrastructure, site development, and public works. I've prepared multi-discipline bid packages, led public and private tenders, verified quantities in AutoCAD and SketchUp, and managed change orders, progress billings, and project closeouts—including the Defensores del Morro Interchange, an approximately USD 80M road project.

I work closely with project managers, procurement teams, subcontractors, suppliers, consultants, and clients to resolve scope gaps and cost impacts. I'm comfortable improving estimating workflows with new tools, including AI-assisted estimating tools.
