I'm a


I am a Senior Mechanical Engineer, practical and versatile, adept of first principles, always a learner, never settling for average.
Acquired significant blue-collar experience and wide exposure in numerous industrial settings over 10 years of field work as millwright.

As a child, my early toys were my fathers tools. He is a very crafty person and a role model for many.
My earliest tinkerings were hobby electronics, such as Stereo amplifiers, FM transmitters, walkie-talkie. Made from scratch, cutting and tracing my own PCB's, carbon-copy / laquor masking and acid etching, drilling, planting and soldering the components.

As my inventory and skills expanded I started providing DJ Sevices for events. During the late 90's disco fever, I partnered with a local businessman and opened a couple of clubs, where I setup and handled the sound and lights systems.

In 1999 I joined the Technical University of Cluj Napoca and specialized in Agricultural Equipment and Processes. During this time I worked in auto shops, restoring bodywork, rebuilding engines, gearboxes and electrical.

While the internet bubble, I met a foreign entrepreneur in some early stages of setting up an internet business in our country. I assisted with hardware repairs and translations, then I became his right hand, managing office space, infrastructure setup, people recruitment, agency website and SEO, finances, payroll and identifying new business opportunities while he was out of country.

In 2005 I graduated DIPL.-ING. equivalent with M.Eng. and soon started my career with PlaurServ, a local engineering consulting company ran by one of the most admired and loved engineer in the area. Traveled to sites, performed field inspections and test and commissioned all range of lifting equipment (such as overhead, tower & mobile cranes, telehandlers, forklifts, aerial lifts, overhang bridge beams launchers, etc.) While employed, I took a 2 year postgraduate program in Road Traffic Engineering, part of Professional and Continual Education with the same university.

Arrived in Canada in 2010 as skilled worker permanent resident and landed jobs as Overhead Crane Technician with Pro Action in Montreal and Hite Services in Sudbury, ON, 2012 thanks to my related experience.

After being blessed with a second child, I decided to leave the crane industries so I can be my familly all the time.

In 2014 I had the provilege to be part of Konecranes, world-leading group of Lifting Businesses™. Started Industrial Millwright apprenticeship with Alberta Tradesecrets as no engineering opportunities.

As a crane technician, I traveled the country far and wide and fixed cranes in almost all industries out there, from mining, lumber, oil & gas, nuclear, steel mills, transportation, utilities, and many others. While working in all these plants, a curious mind will observe and explore interesting facts, processes and concepts and unavoidably records them. After a decade, one can store an amazing database that proves to be so useful in finding insiration for new technologies.

In 2020 I joined CarbonCorp, developer of a revolutionary carbon capture technology transforming CO2 into Carbon Nanotubes using elecrolysis.
I resumed my engineering career as an EIT, in designing and testing new processes and equipment from scratch, where standards are not yet written.

In 2022 I received the P.Eng. with APEGA.
