Freelance TypeScript

We're looking for a frontend developer to help build a cross-chain decentralized exchange (DEX) UI. The ideal person has 3–5+ years of experience with React, Next.js, and TypeScript, and has worked on Web3 apps before. They should be comfortable integrating wallets like MetaMask, WalletConnect, and Coinbase using libraries like Wagmi, RainbowKit, or Web3Modal. Strong knowledge of Ethers.js is key for handling Ethereum and EVM-based chains. Bonus points if they’ve worked with Substrate/Polkadot.js, since the DEX backend is built on that stack. They should understand how wallet connections, signatures, RPCs, and chain switching work, and ideally be able to troubleshoot cross-chain quirks. Experience with decentralized protocols and privacy-focused coins like Monero or Bitcoin is a plus. We want someone who writes clean, maintainable code, is security-conscious (especially around wallet/key handling), and can collaborate with backend and design teams. Experience with Tailwind or similar CSS frameworks is great. It’s a plus if they’ve built or contributed to crypto DEXs, trading UIs, or DeFi dashboards.Reach out and we’ll brief you on the stack, scope, and product vision.

At Bevalty, we are pioneering the alcoholic beverage industry with a new, digital loyalty rewards platform. Our goal is to help brands build compelling loyalty programs that facilitate direct and rewarding relationships with their consumers (never been done before at scale) and to achieve that, we are building our product from the ground up. The company will scale through a SaaS model (B2B) and get consumer distribution through brand relationships (B2B2C), making it a uniquely scalable business, compared to pure D2C.

You will be responsible for developing user interfaces that seamlessly integrate with blockchain technologies using TypeScript and leveraging Web3 integration libraries like ether.js, wagmi.sh, and Thirdweb. Additionally, you will have the opportunity to work with 3D graphics using three.js to create immersive and visually stunning user experiences.
Key Responsibilities:
<ol>
<li>
Front-End Development: Develop and maintain user interfaces for our Web3 applications, ensuring a seamless and user-friendly experience.
</li>
<li>
Blockchain Integration: Integrate blockchain technology into the front-end using Web3 libraries such as ether.js, wagmi.so, and thirdweb to enable decentralized functionality.
</li>
<li>
3D Graphics: Utilize three.js to create interactive and visually engaging 3D graphics for immersive user experiences.
</li>
<li>
Cross-Platform Compatibility: Ensure that front-end solutions work effectively on various browsers and devices.
</li>
<li>
Performance Optimization: Optimize front-end code for speed, responsiveness, and efficiency.
</li>
<li>
Testing and Debugging: Conduct thorough testing and debugging to identify and resolve issues promptly.
</li>
<li>
Documentation: Create and maintain documentation for front-end code and integration processes.
</li>
</ol>
Collaboration: Work closely with back-end developers, product managers, and other team members to achieve project goals and meet deadlines.
