What I'm looking for

I'm looking to build scalable, secure web and mobile products where I can drive architecture, improve UX and reliability, mentor teammates, and deliver business value in fintech, logistics, or blockchain.

I've built production web and mobile products for a multi-chain crypto wallet, Formal Skin, NewAge, Autosled, and Evently. My work spans secure transaction workflows, blockchain integrations, prescription-delivery PWAs, logistics CRM systems, and real-time event platforms.

I use React, React Native, TypeScript, Node.js, and Next.js to create modular architecture, performant user experiences, and reliable CI/CD workflows. I also lead code reviews, mentor developers, and balance scalability, security, accessibility, and business value.
