About Ruben

As an Occupational Safety Specialist (Sifa) with over 17 years of experience in the industry and more than 10 years specializing in occupational safety, HSE management, and process optimization, I support companies in establishing their safety organization in a legally compliant, efficient, and practical manner.

My career at Siemens, Siemens Energy, and Orafol has provided me with extensive experience in production, logistics, and engineering. There, I created risk assessments, implemented occupational safety concepts, and successfully trained and led teams. Through my training as a mechatronics technician and further education as an industrial foreman, I combine technical expertise with business acumen. A combination that has proven particularly valuable in projects.

As a project manager and HSE manager, I have taken responsibility for budgets, safety audits, instructions, and preventive measures, developing sustainable solutions that combine safety and economic efficiency.

Since 2025, I have been working independently, offering companies flexible support in occupational safety, HSE management, and compliance. My focus is on reducing hazards, meeting legal requirements, and protecting employees sustainably. My clients benefit from a clear structure, practical approaches, and my transparent fixed-price model.
