Experienced mechanical engineer and energy efficiency specialist, focused on programming and successful execution of projects applying knowledge of mechanics, hydraulics, pneumatics, steam, energy efficiency, fluid mechanics, thermodynamics, as well as sizing and selection of components and equipment for the manufacturing industry. With a constant interest of learn, share and apply engineering knowledge to the daily challenges at industry in order to solve demanding problems and to keep the continuous improvement of the process.

I help companies take existing CAD designs and make them manufacturing-ready. Clients bring me in when a product already exists but needs to be cleaned up, validated, optimized for DFM, or clearly documented for suppliers and production teams. I typically work on products that are past the concept stage and require senior-level CAD refinement, design validation, and technical clarity before manufacturing or scale-up. You’ll want to work with me if: • You have an existing CAD model that needs cleanup, validation, or restructuring • A design looks fine visually but isn’t ready for manufacturing • Suppliers are asking questions or pushing back on drawings • Assembly logic isn’t clear or documented • You need senior-level DFM feedback before tooling or production • Legacy parts or STL files need to be rebuilt properly My work typically includes: • CAD cleanup, validation, and optimization for manufacturing • DFM-driven design refinement • Reverse engineering from STL, scans, or legacy CAD • Assembly logic definition and exploded views • Manufacturing and installation documentation • Technical animations for assembly, training, and product explanation I usually work in a technical lead or senior contributor role, collaborating with internal engineers, manufacturers, and suppliers. I focus on well-defined, execution-driven projects where accuracy, clarity, and manufacturability matter. My goal is to reduce production risk, supplier confusion, and costly rework before manufacturing begins. I bring over 19 years of experience working with industrial and mechanical products in engineering-driven environments, including projects requiring high accuracy, traceability, and technical rigor. My background in aeronautical engineering brings a strong focus on structure, validation, and design discipline to every project. Tools: • CAD: CATIA V5, SolidWorks • Visualization: KeyShot • Documentation and Graphics: SolidWorks Composer, Adobe Illustrator, Adobe Photoshop
