Summary
At 18, I may not have years of sales experience, but what I do have is an unstoppable drive to win, adapt, and improve. I’ve turned low-paying jobs into high-revenue opportunities, upsold premium products, and launched my own startup, handling everything from branding to supplier negotiations. But at the core of it all, I see everything through sales—whether it’s persuading, negotiating, or finding the angle that makes people say yes. Every conversation is a chance to sharpen my skills, close stronger, and understand people better. In competitive industries like SaaS, AI, and Fintech, there’s no room for hesitation. I do what it takes to win—ethically, strategically, and relentlessly.
