PERSONAL SUMMARY

Self-starter and diligent professional with 9 years of experience in e-commerce who managed a full cycle of B2B
and B2C sales, complemented by 10 years in financial markets. By providing outstanding customer service and
possessing excellent negotiation skills, I have achieved notable success delivering a 34% conversion rate from the free
trial in SaaS sales. I led a competitor analysis initiative, and alongside the marketing team, achieved a 15% growth in the
customer base.
My experience as a Sales Manager has led to significant accomplishments, including expanding the product line

equipment and expanded the customer base. I enhanced brand recognition globally through direct negotiations with

image worldwide.
As a Brand Manager, I effectively resolved issues related to Amazon sales, including optimizing listings and
compliance, developed and improved SEO for new products, and implemented strategies to address return rates, all of
which enhanced product quality and efficiency.
During my tenure in financial markets, I developed unique research and presentation skills, applying those to
