I build the brands and experiences that drive revenue.

From co-architecting the rebrand during a major adtech platform merger to building global programs that accelerate enterprise deal flow, I combine creative soul with the operational rigor needed to lead brands through high-stakes transitions.

My career was forged in experiential marketing. It wasn't just a channel for me. It was a discipline for understanding how people engage, decide, and commit. That specific perspective now guides how I lead brand, go-to-market, and growth strategies for complex organizations.

I build the systems that keep brand, product, and revenue moving in the same direction. My goal is to make sure every interaction, whether it is a digital campaign or a live event, delivers a real result for the business.

I design marketing from the customer’s point of view.

How I create impact

  • Growth works best when strategy and execution move together. I design go-to-market programs that focus less on volume and more on momentum: clear messages, aimed at the right audience, delivered at the right moment.

    At InMobi, I designed storytelling initiatives that drove a 150% increase in enterprise leads and significantly improved lead quality. Throughout my career, I have partnered closely with sales and product teams to ensure marketing efforts support real business outcomes, not just activity. To me, growth is about clarity, focus, and repeatable impact.

  • Experiential is how I learned to think about customers. When you put real people in real environments, you see what captures attention, what creates trust, and what actually moves behavior. That lens informs how I approach every customer interaction, whether live, digital, or somewhere in between.

    At Magnite, I led 50+ annual customer programs across five continents. By launching the Executive Exchange program, I helped drive a 36% increase in multi-company deal activity by deepening C-suite trust and dialogue. My goal is always the same: create experiences that make people lean in, not check out.

  • A brand is not a logo or a color palette; it is the feeling people associate with you before they ever buy. I help companies define what they stand for, why it matters, and how to show up consistently across every touchpoint.

    I specialize in leading brands through high-stakes transitions. At Magnite, I unified visual identity and messaging across North America, EMEA, APAC, and LATAM following a major acquisition. At Audience Town, I rebuilt brand identity for new segments, driving a 400% increase in social engagement. My approach blends insight, storytelling, and instinct to create brands people recognize, trust, and choose.

  • Good content earns attention by being useful, relevant, and human. I approach content as a strategic tool, not filler. I specialize in turning complex products into clear narratives; for Playmaker Sports Media, I am currently building a flagship content and newsletter ecosystem from the ground up to differentiate the brand in a competitive adtech category.

    At Audience Town, I built a full-funnel content strategy that improved engagement and strengthened SEO performance. What matters is content that moves people closer to action.

  • Social works best when it feels like participation rather than promotion. The strongest brands listen as much as they speak, and they know when to join the conversation and when to step back.

    At the Shorty Awards, I reimagined a legacy program as a digital-first experience, reducing production costs by 80% while expanding reach by 200%. I view social as a high-leverage extension of the brand experience, especially during live moments, launches, and cultural inflection points. When done right, it reminds people there are real humans behind the brand.
