Worked as an Mechanical Design Engineer & Systems Integrator specializing in Product Design & Development for Multiple Engineering sectors providing end-to-end design and engineering support that helps businesses move from concept to production with confidence. From design thinking workshops and ideation sessions to 3D modelling, simulation, and optimization, I ensured every stage of development is creative, technically sound, and manufacturable. From reverse engineering an existing product, validating a new concept, or streamlining design for manufacturing, I made sure, the solutions are practical, efficient, and aligned with industry standards.
