What I'm looking for

I seek hands-on roles in structural detailing, site engineering, or QA/QC within collaborative construction teams where I can grow into project management.

I am a Registered Civil Engineer with practical experience in structural detailing, site supervision, and quality assurance across steel and reinforced concrete projects.

I have prepared fabrication, erection, and as-built drawings using Tekla and AutoCAD, developed 3D models in SketchUp, and supported surveying activities with a Topcon total station.

On site, I performed QA/QC tasks including slump tests, compressive strength testing, field density tests, bolt and baseplate inspections, and supervised daily construction workflows to ensure adherence to specifications.

I seek to leverage my detailing, field engineering, and surveying skills to contribute to complex structural and industrial projects while continuing to grow in project management and construction engineering roles.
