I'm a Civil Engineer registered with the Engineering Institution of Zambia (EIZ No: SMENG2025078116), with hands-on experience across site supervision, structural drafting, and construction project delivery. I currently lead operations at Aminnph Investment Zambia Limited, overseeing construction material supply chains, heavy equipment deployment, and site-level engineering decisions for renovation and new-build projects. Previously, I served as Site Engineer on the full upgrade and renovation of a fuel station in Lundazi — managing BOQ verification, material procurement, subcontractor coordination, and structural finishing works from start to finish. I also completed an internship with Zambia's Ministry of Infrastructure, where I conducted structural condition assessments of public buildings and helped develop preventive maintenance schedules used in national infrastructure planning. On the technical side, I work in AutoCAD, Revit, and GIS mapping for civil and architectural drafting — including drainage design, road engineering, and residential building layouts corrected to local building codes and standards. I'm also experienced in BOQ quantity estimation and cost breakdowns, having prepared full bid packages and tender documents for engineering firms. I bring the same attention to detail from active construction sites into my remote work: clear communication, accurate documentation, and delivery you can rely on. Whether you need a set of drawings converted to AutoCAD, a bill of quantities built from your drawings, or support on a civil design project, I'm ready to get started.
