– Designed manual and robotic welding fixtures with engineering focus on part positioning accuracy, clamping stability, fixture
repeatability, weld accessibility, and ease of fabrication —generating weld sequence plans and CSV coordinate datasets for
robotic path programming.

– Managed complete product development lifecycle in SolidWorks EPDM: weldment modeling, detailed manufacturing drawings, revision control, BOM management, and production coordination from client requirement capture through final drawing release.

– Applied GD&T as per ASME Y14.5 and performed tolerance stack-up analysis to ensure dimensional control, assembly
fitment, and consistent quality across production batches.

– Implemented macro-driven SolidWorks EPDM workflows to standardize repetitive drawing tasks and improve team
throughput across active project deliverables.

– Engineered hydraulic gantry structural assemblies integrating hydraulic cylinders, weldment frames, and mechanical lifting
mechanisms.

— covering structural load calculations and assembly drawing release.
