I’ve always believed the best leaders don’t just build great products – they build great people. Over the past decade, I’ve led engineering teams at LinkedIn, Netflix, and now Salesforce, where I serve as Director of Engineering for our Analytics Agent org. My focus: transforming how we build intelligence, not just software. From architecting AI agents that power Tableau’s next-gen analytics, to driving cross-functional collaboration across global teams, I thrive at the intersection of vision, velocity, and impact. But my mission goes beyond what happens inside one company. Through Peak Potential, the career accelerator I founded, I’ve helped hundreds of senior engineers and leaders grow into staff-level and leadership roles. I’ve seen firsthand how the right mix of mindset, mentorship, and strategy can unlock careers – and change lives. Whether I’m coaching engineers to find their voice, scaling systems for millions, or running and scaling a business (yes, I believe in bringing heart to everything I do), I lead with purpose and a deep belief in the potential of people. If you're building the future of tech, growing into your next big role, or reimagining what's possible – let’s connect.
