Hello.I have been working with React/Node.js for more than 8+ years.I'm ready to coopearate.

Hello,

I meet all the core requirements for your full-stack Web3 developer role — with over 7 years of full-stack experience and more than 5 years in Web3 and blockchain projects. I hold a Bachelor’s in Computer Science and have built production-ready applications using Next.js, React, and TypeScript, including SSR/SSG optimization and scalable frontend architectures.

On the backend, I work with Node.js (Nest.js, Express) and PostgreSQL/MongoDB, focusing on clean API design and performance optimization. My Web3 experience includes Solidity smart contracts, wallet integrations (MetaMask, WalletConnect), and The Graph for on-chain indexing. I’ve contributed to NFT marketplaces, DeFi dashboards, and custom DApp integrations.

I’m confident in handling full-cycle system design — from requirement analysis to deployment — and can quickly adapt to new blockchain ecosystems. Fluent in technical English and comfortable working with open-source codebases.

Let’s discuss your product vision — I can start immediately.

Best regards,
Jeo Vincent Carretas

My expertise spans end-to-end architecture — from backend API design and database optimization to front-end SSR/SSG rendering for seamless performance. I’m passionate about building reliable DApps, NFT platforms, and DeFi tools that align with both business logic and blockchain best practices. I’m confident that my technical depth and autonomous problem-solving approach will add real value to your team and help drive your Web3 vision forward.
