As the CEO and founder my responsibilities have to do with pretty much everything in the company. From securing funding to internal operations to securing partnerships and customer acquisition, no task is beyond the boundaries of my responsibilities. My average work day involves doing legal work, finding the right partners to help us excel, overseeing product development and maintaining a positive team dynamic, which is my most important task. Through my past experience with finding a social innovation start-up (Pak-Story), being the Vice President at Pi Kappa Alpha Fraternity, and being a part of the varsity rugby team at University of Waterloo, I have developed a great extent of interpersonal skills which have allowed me to be leader for this team. Growing up, I attended 12 different schools, which assisted me in developing my social skills in the process of adapting to different environments. What I envision from this company is continued leadership towards the innovation of the best practices regarding safety worldwide. I believe that every goal you set is achievable if you are persistent with your effort, and intelligent with your resourcefulness.

As Chief Financial Officer of Guard-Ex, I am primarily responsible for finance and accounting related activities. This includes but not limited to day-to-day banking activities, bookkeeping, maintaining CRA standards, strategic partnerships, SR-ED filing and financing rounds. As a determined founder, I am consistently mirroring a lead role for a variety of other departments including Operations and Human Resources. I develop plans and strategies to ensure research, product development & talent acquisition are planned consistently to feasibly be aligned for financial execution. Moreover, I take a strong stand for recruiting and selecting talent. I am responsible for accurately assessing talent gaps and ethically execute employment agreements. All that being said — since the establishment of our startup, the entire founding team is determined to make a difference and honestly believe that nothing is impossible. Any task can be completed if an individual is adamant to achieving their fixed goals — considering the amount of resources and educational institutions within our fingertips.
