Senior Product Manager | Web3 & Fintech
Product manager with around 10 years of experience working in crypto, fintech, and Web3. I've worked on technically complex products — DeFi protocols, AI trading platforms, institutional staking dashboards, and developer-facing infrastructure like SDKs and data pipelines. I'm comfortable working directly with engineering teams and translating what a business needs into something that can actually be built and shipped. I've also spent time on the operational side, including a COO role where I helped scale a crypto company from 30 to 150+ people.
