Blockchain Engineer

I'm a Software Engineer with a background in blockchain infrastructure, backend engineering, and financial technology. I recently graduated from Duke University with a Master of Engineering in Financial Technology.

My experience spans Ethereum, Solana, smart contracts, cross-chain systems, and full-stack web development. I've built production-ready applications using TypeScript, Node.js, Next.js, NestJS, PostgreSQL, Prisma, Docker, and REST APIs, and have developed blockchain solutions including ERC-4337 account abstraction, ERC-7593, and cross-chain payment infrastructure.

Beyond blockchain, I'm passionate about AI-powered software development and have hands-on experience working with OpenAI APIs, Claude, Gemini, and prompt engineering. I enjoy building scalable systems that combine AI, backend services, and modern cloud technologies.

I'm currently seeking Software Engineer, Backend Engineer, Blockchain Engineer, AI Infrastructure, or Platform Engineer opportunities where I can build reliable, secure, and scalable systems while continuing to grow as an engineer.
