About
I'm a seasoned tech marketer and go-to-market (GTM) program manager with a proven track record of launching products and driving adoption across both B2B and B2C markets. I’m passionate about storytelling and crafting customer experiences that truly resonate. With deep expertise in GTM strategy, I lead cross-functional teams to deliver impactful launches in fast-paced, high-growth environments. I build scalable processes that support sustainable growth, and I thrive in ambiguity—where success is driven by trust, initiative, and precision. I bring a blend of strategic thinking and operational discipline to every challenge. As a people-first leader, I’m committed to developing talent and cultivating strong, collaborative relationships across teams and with external partners.
