Front End Developer

Web3 Front End Developer

I’m a Web3 Developer passionate about building intuitive, scalable, and decentralized web applications. With a strong background in React, TypeScript, and blockchain integration, I specialize in crafting seamless user experiences that bridge traditional web interfaces with the power of decentralized technology.

Over the past few years, I’ve worked on dApps, NFT platforms, and DeFi dashboards, collaborating closely with smart contract engineers to bring complex blockchain interactions to life. My work focuses on delivering clean, responsive interfaces while maintaining robust security and performance standards across the stack.

I’m deeply interested in Ethereum, Layer 2 solutions, wallet integrations (MetaMask, WalletConnect), and exploring how Web3 UX can evolve to onboard the next billion users. When I’m not coding, I contribute to open-source projects and stay engaged with the developer community through hackathons and technical writing.

Tech Stack: React, Next.js, TypeScript, Python, TailwindCSS, Ethers.js, Web3.js, Wagmi, Solidity (basic), GraphQL, and Node.js.
