About

I’m a technical builder who moves between engineering, product, and customer experience - the kind of person who can design and scale backend systems, align cross-functional teams, and explain a system clearly to someone non-technical, all in the same afternoon. At high-growth startups and in fast-paced environments, I’ve led platform re-architecture efforts, launched 100+ core features, scaled experimentation velocity 10x, and evaluated AI tools that shaped company-wide integration strategy. My work has supported products with millions of daily users and multi-million-dollar revenue streams - but I’m just as energized helping a product team iterate faster or enabling a customer to self-serve a new integration. What ties it all together is this: I’m driven by the belief that good systems should make people feel capable. When tools are intuitive, fast, and reliable, teams are freer to create, solve, and scale without distraction - and I love building toward that.

  • (Backed by Sequoia, Scale, Y-Combinator, SV Angel and more)
  • I help bridge the gap between cutting-edge research and real-world adoption. As a Solutions Engineer, I design and build AI Human experiences end-to-end - whether that means architecting integrations, developing internal tools, or optimizing customer workflows for scale. My goal is to ensure teams don’t just adopt our technology, but unlock its full potential to create meaningful, human-like interactions at scale.
