About

I am a Civil Engineer, AutoCAD Drafter, Revit BIM Modeler, and Construction Estimator with 4+ years of experience supporting construction, residential, infrastructure, and telecommunications projects.

I help architects, engineers, contractors, and construction teams turn plans, field information, markups, and project requirements into accurate and organized technical deliverables.

My experience includes AutoCAD 2D/3D drafting, construction drawings, as-built updates, redline revisions, quantity takeoffs, architectural and structural plan review, GIS-based layouts, and hands-on Revit structural modeling.

I have supported telecommunications infrastructure projects, a 33-building residential development, municipal infrastructure, and fabrication/construction environments. This gives me a practical understanding of both technical drawing production and field execution.

Services I can provide include:

• AutoCAD drafting and drawing revisions
• Revit BIM modeling
• Residential and structural drafting support
• Construction documentation
• As-built drawings and redline updates
• Quantity takeoffs and estimating support
• Shop and fabrication drawing support
• GIS and site layout drafting

I am detail-oriented, reliable, comfortable working in English, and available for ongoing remote collaboration with international clients.

Software: AutoCAD, Revit, ArcGIS, Google Earth, Primavera P6, MS Project, Microsoft Excel
