About me

I am a mechanical engineer with 12 years of experience in the field. I've worked with a wide variety of sub disciplines and have deep knowledge in CAD, piping, pressure vessels, rotating equipment and plant design.

My main strengths are curiosity, a large knowledge pool and skill in applying it in the real world. I have done this in a variety of mechanical engineering fields like hydraulics, pneumatics, materials, structural and thermodynamics. But also in a wide area of Electrical, process and IT.
