I started working as a design engineer in 1992 at WEFOMA in Bietigheim-Bissingen (Germany), where I also completed my apprenticeship as a toolmaker. In the period 1992-1996 I did my studies as a technician at the Max-Eyth School in Stuttgart, which I successfully completed in January 1997. Until our emigration to Switzerland in 2008, I was able to gain design experience in various areas at the WEFOMA company. The design of aluminum die casting molds and of drawing and punching tools were my main focus, as well as drawing creation and data preparation on the Catia V5 system. From October 2008 to August 2021 I worked for the company KEBO. (Switzerland) My responsibilities ranged from the design of plastic injection molds for well-known customers in the medical and packaging industries, assistance in new developments and innovations, design of complex assemblies, detailed designs and drawing derivations, the supervision of the production process to the support of data preparation, archiving and all data traffic. The safe handling of the CAD system Siemens NX in connection with Teamcenter is self-evident for me, so that I also give internal trainings in this area. In addition, I have built up and expanded standardization to ensure easier and more efficient work. From April 2015 to March 2016, I was appointed in the context of a partnership with a company in the USA, to build up a new design office and to introduce the new software Solid-Works. There I successfully managed and trained the staff.

I'm a fresh graduate from Alexandria University with a bachelor's degree in Electromechanical Engineering. I have always been a fast learner with the ability to always come up with new ideas and solutions which drove me to pursue an engineering degree to help change the world into a better place and improve people's lives. I have worked on different projects related to the automotive, robotics, and construction fields. 1- I spent 3 years in an FSAE team from working on the fuel system, becoming the engine sub-team lead to being the chief design engineer of the team, and taking the decision to stop working on IC vehicles and start working on an FSAE EV. 2- Designing and programming a mini palletizing robot for a robotics course and manufacturing it using 3D printing technology. 3- Designing a Bionic arm where I designed and manufactured 2 prototypes using 3D printing technology (prepared the 3D printing files and printed them myself) and collected anthropometric data to support my design decisions. 4- Designing the electrical floor lighting and power plans for an educational building as a part of my Codes and Specifications of Electrical Systems course. Currently, most of my experience and knowledge is in mechanical engineering with some knowledge and experience in electrical engineering, making me suitable for projects requiring a mechanical engineer to work closely with electrical engineers for better systems integration.

My name is Mack and I am a Mechanical Design professional located in Colorado, USA. I specialize in lightweight component design for Robotics and Autonomous Systems as well as hardware design for Aviation and Outdoor Extreme Sports. I also operate a CNC Machine shop and test facility. We specialize in nonferrous metals. As a certificated Mechanical Designer, I am not only an expert in 3D Modeling/CAD, but I am also well versed in Drafting Standards, CNC Manufacturing Standards, Geometric dimensioning & Tolerancing(GD&T) and I implement Quality control processes in my design workflow. This saves on time and stress as your project continues. I am open to most projects, but keep in mind it is mutually beneficial if I work on projects I have a deep interest in. I have worked on projects from Offroad race trucks to Drones and robots for the film industry. My field of continued study is mostly in the realm of lightweight, mechanical components for Robotics and drones. However, my experience is far-reaching and my knowledge gained in the industry has numerous applications. I typically like to do a short discovery session to see if I can be useful on your project.
