About

I am a Mechanical Design Engineer with over 10 years of experience in mechanical design, product development, 3D CAD modeling, and engineering design.

I specialize in turning product ideas, sketches, and existing designs into practical and detailed 3D CAD models. My experience includes mechanical product design, custom mechanisms, electronic enclosures, robotics systems, educational models, assemblies, technical drawings, design improvement, and engineering documentation.

I have experience handling complete product development workflows, including concept development, 3D CAD design, design iteration, mechanical analysis, SolidWorks simulation, technical drawings, visualization, and preparation of STEP and manufacturing-ready files.

My main services include mechanical and product design, SolidWorks 3D modeling, enclosure design, assembly design, prototype development, technical drawings, design improvement, CAD conversion, product visualization, and design-for-manufacturing support.

I focus on practical engineering solutions, accurate CAD work, attention to detail, and clear communication. I am available for both short-term CAD projects and long-term product development collaborations.

Experience

Mechanical Design Engineer E-Square Young Engineers Franchising Ltd · Full-time Dec 2020 – Present 5 yrs 7 mos Sri Lanka Responsible for mechanical design and product development for educational engineering and robotics systems. My work includes concept development, mechanical model design, custom mechanisms, motorized systems, CAD development, assemblies, product improvement, and technical documentation.

I develop practical engineering solutions within strict component and design constraints, including robotics models, competition systems, educational products, and mechanical prototypes.
