What I'm looking for

I seek a role where I can apply ASTM laboratory and field testing expertise to ensure material quality, contribute to QA/QC processes, and support infrastructure projects with clear reporting and hands-on testing.

I am an experienced construction materials laboratory technician with decades of hands-on expertise in ASTM testing for soils, aggregates, concrete, and asphalt. I have performed and supervised laboratory and field testing—including sieve analysis, CBR, compaction, moisture content, compressive strength, and Marshall asphalt testing—on projects in the Philippines, Saudi Arabia, and Micronesia.

I bring practical skills in trial mix design, concrete admixture application, field density testing, and construction surveying (horizontal/vertical layout and setting elevations). I consistently deliver accurate test results and reports to support quality assurance on infrastructure and building projects.
