I am a seasoned mechanical and piping designer with extensive leadership experience delivering 3D models, P&IDs, stress analysis, and fabrication drawings for life sciences, oil & gas, and manufacturing projects. I excel at coordinating multi-discipline teams, optimizing design workflows, and ensuring deliverables meet API, ASME, and industry standards while staying aligned with client goals. In parallel with my design work, I enjoy mentoring junior designers and teaching CAD and project management best practices to help teams work more efficiently across cloud-enabled collaborations. When I’m not creating models or leading design efforts, I teach AutoCAD and CADWorx as an Adjunct Instructor, focusing on file management, cloud storage, and cross-disciplinary collaboration. I am passionate about problem solving, QA/QC, and converting complex requirements into clear, buildable solutions that stand up to field realities and inspections.
