Eng mattan Abdilahi

I am a Civil and WASH Engineer with 15 years of field experience delivering complex infrastructure across Somaliland, Somalia, Turkey, and Syria. My expertise spans watershed management, soil and water conservation, hydraulic structures, and flood-defense modeling. As a Resident Engineer, I direct contractor operations, supervise civil works, and ensure donor-funded projects meet rigorous technical and QA/QC specifications. I focus on climate resilience and sustainable infrastructure through strict engineering standards.
