I prepare engineering drawings using AutoCAD and Revit. My previous role was with a company specializing in the design and construction of water and wastewater treatment plants, where I produced 3D models, Piping and Instrumentation Diagrams (P&IDs), fabrication drawings, and general plant layouts. I also develop engineering drawings for plumbing, fire protection, and HVAC systems. I am a Filipino-registered Mechanical Engineer and Master Plumber, licensed by the Professional Regulation Commission in Manila.
