Professional profile

From mechanical design to industrial execution.

Senior Mechanical Engineer with broad experience in product development, mechanical systems, structural design, tooling, validation and industrialization. My background spans wind energy, aerospace, advanced mobility, automotive, rail, bathroom products, domestic ventilation and industrial tooling, with a strong focus on bridging engineering intent, manufacturing reality and test feedback.

My contribution is not limited to creating 3D models: I help teams converge on robust solutions, reduce ambiguity and move complex designs towards production, suppliers, validation and industrial implementation.

Core expertise

Senior engineering capability across the product lifecycle.

Mechanical design leadership

Concept development, architecture definition, mechanical integration, design reviews and technical decision-making for complex assemblies and industrial products.

CAD / PLM / documentation

Advanced Siemens NX and Teamcenter experience, detailed drawings, configuration discipline, release processes, GD&T, tolerancing and technical documentation.

Manufacturing & suppliers

Design for manufacturability, supplier coordination, workshop support, tooling, production feedback and practical problem solving from prototype to industrial implementation.

Testing & validation

Mechanical validation, test benches, GRP bonding tests, structural test support, issue resolution and design improvement based on physical evidence and test results.

Cross-sector engineering

Experience in wind energy, aerospace, advanced mobility, automotive, railway, domestic ventilation, bathroom products, plastic parts, sheet metal and industrial structures.

Team and stakeholder coordination

Coordination of designers, suppliers, manufacturing teams, validation groups and international stakeholders in multidisciplinary engineering environments.

Selected experience

Industrial background with exposure to high-demand engineering environments.

Quest Global / GE

Wind energy design, factory support and validation projects

Worked as a Quest Global contractor directly integrated into GE environments. First phase: Siemens NX design work for wind-turbine tower and nacelle-related systems, leading a small team during design implementation. Factory phase: design liaison at manufacturing suppliers such as Haizea Wind, supervising complex internal tower integration operations, validating design directives and providing feedback between factory and engineering teams. Protolabs phase: design of test benches, validation tooling, load-cell fixtures, yaw-bench tooling, ladder-service test structures and climate-chamber adaptations for GE and other industrial clients.

HyperloopTT

Docklock primary specifications and capsule access systems

Short but highly significant advanced-mobility project. Defined primary specifications for several Docklock subsystems: the door/interface connecting the external depressurised tube environment with the capsule interior. Work included docking and approach mechanisms, door-opening concepts and subsystem-level requirements for a capsule concept intended to travel at approximately 1,000 km/h in a depressurised tube, with aerospace-style safety and integration constraints.

Airbus / A400M

Large structural design for aerospace testing

Principal design work for a large A400M engine-test structure, requiring robust mechanical architecture, manufacturing awareness, heavy structural design and demanding test-environment constraints.

Ingedetec / SEAT Technical Centre

Automotive plastic components, surfacing and validation

CATIA V5 design and surfacing work for lighting components, including headlamp housings and rear lamp lens surface repair/preparation for injection-mould tooling. Later validation work at SEAT facilities for luggage-compartment trim and moulded foam tool carriers.

RDT Ingenieros

Product design, aerospace fixtures and rail interiors

Engineering work for Soler & Palau, Serra Soldadura and IDD. Projects included the Silent Design 100 domestic extractor fan, large welding/assembly fixtures for aerospace structural components, Talgo high-speed train bathroom interiors and CAF Besançon tram full-scale mock-up work.

Roca Sanitario

Bathroom furniture, accessories and wellness systems

Product development work in bathroom furniture, accessories and wellness products, including the Wellsuite / Wellness Center environment. Experience with user-facing products, plastic components, assembly details and bathroom-system integration.

Altran / Frape Behr / MAHLE

Automotive thermal-management plastic parts

Siemens NX product design for radiator and intercooler plastic tanks, mainly glass-fibre reinforced plastic components for automotive thermal-management systems, including Alfa Romeo and Opel programmes.

Early tooling experience

Sheet-metal tooling and stamping dies

Manufacturing-oriented foundation in sheet-metal tooling, stamping dies and large mechanical tools, building practical knowledge of robustness, tolerances, machining constraints and workshop realities.
