About Me

I'm a passionate mobile and web engineer with 8+ years of experience building production-grade applications that serve millions of users worldwide.

My expertise sits at the intersection of React, Next.js, React Native, TypeScript, and Web3 technologies. I've led the development of both crypto-native and traditional mobile and web applications, spanning fintech platforms, consumer products, and scalable SaaS solutions. Whether it's integrating complex wallet flows and secure transaction systems, or building high-performance e-commerce and productivity tools, I bring the same level of technical rigor and attention to detail.

I believe in writing clean, maintainable code that scales across platforms. My approach blends strong architectural decisions with a deep focus on user experience, security, and performance optimization, from frontend to production.
