Summary

With over 15 years of experience working for companies and operating my own businesses, I have developed strong attention to detail, organizational skills, and the ability to perform effectively in fast-paced, high-pressure environments. As a business owner, I independently managed operations and successfully grew my companies to a combined peak of approximately $1.5 million in annual sales.

Over the years, I attended the SEMA Show for seven consecutive years representing our businesses, where I gained valuable experience in customer engagement, networking, product presentation, and relationship building. I also developed experience in cold calling, negotiating contracts through email communication, and managing long-term customer and vendor relationships.

After many years of entrepreneurship and e-commerce management, I am now seeking a long-term career opportunity where I can contribute my experience, continue growing professionally, and fully dedicate myself to a stable and growth-oriented company.
