About

I am a mechanical design professional with hands-on industrial experience in product development, component design, and manufacturing documentation. My experience comes from working in a real production environment where I gained exposure to shop-floor operations, quality processes, and practical engineering problem-solving.

My core strengths include mechanical design, reverse engineering, 2D manufacturing drawings, and support for new product development. I have worked on converting physical components into accurate engineering drawings, refining existing designs, and developing new product concepts based on market and functional requirements.

During my industrial training, I worked on the design and modification of gas regulator assemblies, including the development of new components and full assemblies while considering functionality, manufacturability, and design clarity.

I focus on transforming ideas or existing products into precise, production-ready designs with clear documentation. My approach emphasizes practical design logic, neat technical drawings, and solutions that are efficient to manufacture, assemble, and maintain.
