About me

Chartered Mechanical Engineer (CEng) with more than 20 years of professional experience in mechanical design, product development, engineering analysis, validation and technical problem-solving for industrial equipment, electrical machines and rotating machinery.

Advanced Mechanical Design & Engineering Analysis
Over 20 years of experience in mechanical design, structural analysis, and validation of industrial equipment and rotating machinery, covering the complete product development process from concept generation and R&D to NPI, testing, industrialization, and field support.

Finite Element Analysis (FEA)
Extensive expertise in FEA-driven design diagnostics using tools such as ANSYS Mechanical (APDL, Workbench), nCode, and LIMIT, covering static, fatigue, vibration, and thermal analyses to ensure structural integrity and compliance with customer and regulatory requirements.

Value Engineering & Design for Six Sigma (DFSS)
Strong background in Value Engineering (VE), Component Engineering (CE), Design for Manufacturing (DFM), and Design for Assembly (DFA), with practical experience applying DFSS, DFMEA, PFMEA, and FMEA methodologies to improve product quality, reliability, and manufacturability.

New Product Introduction (NPI)
Full project lifecycle ownership spanning R&D, NPI, rapid prototyping, large-scale refurbishment, and grid compliance, translating functional requirements into robust mechanical architectures with modular design principles.

Rotor-Dynamic & Vibration Analysis
Leadership in rotor-dynamic, lateral and torsional vibration, and critical speed assessments for high-speed rotating equipment, including bearing oil-film/damping modeling, unbalance response evaluation, campbell diagram, and stability analysis to ensure API/ISO compliance.

GD&T & Tolerance Analysis
Production of detailed CAD models and manufacturing drawings including GD&T and tolerance stack-up analysis, supported by certifications in GD&T, Tolerance Analysis, and Engineering Drawing Interpretation.

BOM Management & Optimization
Experience supporting BOM creation, engineering change implementation (ECN), supplier evaluations, manufacturing process reviews, and product cost optimization activities.

Materials Engineering & Fatigue Assessment
Application of FKM Guideline for fatigue strength assessment of mechanical components and VDI 2230 for bolted joint design and verification, combined with strain-gauge testing and metal fatigue analysis using nCode, ANSYS, and LIMIT.

CAD & PLM Software Proficiency
Extensive hands-on experience with CAD and PLM platforms including Creo Parametric, SolidWorks, Autodesk Inventor, Siemens NX, AutoCAD, SpaceClaim, PTC Windchill, Albatros PLM/Migration, SimiMotion, and Leica Cyclone.

Design Validation, Verification & Root Cause Analysis (DVP&R, RCA)
Data-driven engineering and rigorous validation of integrated mechanical subsystems, including root cause analysis, risk assessment, and continuous improvement activities using Six Sigma Green Belt methodologies.

Project history

Senior Mechanical Engineer & Technical Project Lead

ProFluxx, Craiova, Romania
Leading advanced mechanical design, structural analysis, and validation for complex power generation (1.0-40 MVA), automotive, and industrial systems in compliance with ISO standards. Responsibilities include FMEA-based risk management, FEA-driven design diagnostics, rotor-dynamic analyses, BOM management, thermal management solutions, and standardization of mechanical design documentation and validation processes.

Principal Mechanical Engineer - Electrical Machines

Safran Electrical & Power, Pitstone, UK
Spearheaded design engineering activities across multiple projects from concept through development and qualification testing. Performed comprehensive design calculations, produced detailed CAD models and manufacturing drawings including GD&T and tolerance stack-up analysis, and ensured adherence to the Product Introduction Process (PIP).

Senior Mechanical FEA Specialist

Cummins Generator Technologies, Stamford, United Kingdom
Managed research, design, and development for AvK synchronous generators across marine, industrial, mining, and oil & gas applications. Applied LS-DYNA and nCode for nonlinear transient analyses and fatigue assessments. Led Value Engineering and Component Engineering initiatives delivering 22% manufacturing cost reduction. Redesigned critical generator components improving strength-to-weight ratio by 25% and reducing maintenance time by 70%.

Mechanical R&D Design Engineer

Cummins Generator Technologies, Craiova, Romania
Supported end-to-end product development from concept through production for generator systems and components. Applied FEA and analytical methods to reduce design flaws by approximately 50%. Implemented Six Sigma methodologies to improve manufacturing efficiency by 25%. Invented and patented an improved rotor wedge design (EU/GB Patent GB2509735), increasing product performance and thermal efficiency by approximately 20%.
