What I'm looking for

I’m looking for a role where I can own cost control and contract administration, manage tenders end-to-end, drive cost savings, and deliver on-budget outcomes—while partnering with teams that value process improvement and strong reporting.

I’m a results-oriented Quantity Surveyor and Civil Engineer with nearly ten years of experience in cost control, contract administration, and project delivery across diverse construction sectors. I’m known for reducing costs, managing contracts efficiently, and delivering projects of varying scales—while staying focused on accuracy and commercial risk.

In recent roles, I prepared accurate and competitive quotations, managed client negotiations, and increased job win rates through effective follow-up. I owned the full tender process (including BOQs and subcontractor documentation), reviewed and tracked contract terms, controlled project costs through forecasting and rapid response to overruns, and managed variations and valuations from identification through client approval and invoicing.

I also bring strong technical drafting capability—using AutoCAD, STAAD, Revit, and Sketch-Up—and I’ve supported process improvement by streamlining commercial operations and reporting with digital project management tools (including Procore and Simpro). From pre-tender site assessments to monthly progress claims and final account reporting, I work collaboratively in agile teams and provide hands-on support to senior leadership.
