What I'm looking for

I seek remote opportunities in innovative startups, particularly in blockchain and e-commerce, where I can leverage my full-stack skills and contribute to product-driven projects.

I am an experienced full-stack developer with a strong background in building scalable platforms and deploying production-level smart contracts. I co-founded a comic platform that grew to 700K monthly active users and 5,000 transactions per second, leading the end-to-end development and infrastructure. My expertise spans the full stack, including Vue, Laravel, Rust, and Solidity, allowing me to take products from idea to launch successfully.

Throughout my career, I have delivered multiple NFT, DeFi, and P2E projects across major blockchain networks such as Ethereum, Solana, and Klaytn. I focus on clean architecture and maintainability, thriving in remote-first environments that emphasize asynchronous communication. My ability to work independently and drive product development has been a key factor in my success.
