What I'm looking for

I seek frontend/Web3 roles where I can design scalable architectures, build production SDKs/libraries, collaborate cross-functionally, and mentor teams in an Agile environment.

I am a frontend developer with 5+ years of experience building Web3 and product-oriented applications, focusing on production blockchain systems and user-facing products.

I have owned complex frontend areas, designed scalable architectures (Feature-Sliced Design), and implemented smart contract interactions using tools like viem, ethers.js, and web3.js.

I have developed and published production-ready NPM libraries, integrated multiple wallet providers (WalletConnect, MetaMask, web3Modal), and implemented cross-chain solutions including Solana support.

I collaborate closely with backend engineers and designers, participate in technical planning, mentor team members, and drive quality through Storybook, testing, and clear architecture principles (OOP, SOLID, DRY, KISS).
