  Co-Founder

  Max Bound

  Max Bound is a small automotive parts and accessories business. Even though it has nothing to do with the tech field, it was a huge step in my life.
  I had to take on multiple roles to keep the business going, step out of my comfort zone, learn, and adapt to gain practical insights of how a small business can run and survive in an unforgiving market.

  We were also a wholesale supplier for various products, so we dealt with suppliers as clients on a daily basis as well as retail clients.

  I had lots of responsibilities and information to keep track of, managing revenue and budget, keep track of orders, taking decisions when it comes to stock control, and acting as a focal point of contact, but that didn't stop me from using my hobby at the time by creating various C# desktop applications that acts as helpers along with our POS system.
