I’m a software engineer with around six years of experience building scalable, user-focused applications, now specializing in Web3 and blockchain development. Over the years, I’ve grown into a tech lead role, where I’ve guided teams and projects from prototype to production, balancing clean architecture with fast iteration.

My background spans both frontend (React) and backend (Node.js, Django, Oracle, Druid) systems, giving me a strong full-stack perspective. I’ve also worked on smart contracts with Solidity and enjoy tackling both the theoretical and practical challenges of decentralized applications. I’m comfortable leading rapid-prototyping efforts—whether that’s integrating AI agents into workflows, building SDKs for developers, or architecting crypto-focused platforms.

I’m passionate about the intersection of AI and Web3, exploring how agents, decentralized systems, and user-friendly experiences can come together to create products with real impact. With my mix of technical depth, leadership experience, and a constant drive to learn, I bring both execution and vision to any project.
