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

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.

What needs to be done: conduct an independent expert consultation on the implementation of multisig wallets to protect the company's treasury funds, which operates with high-volume payment processing in USDT across three networks - TRON (TRC20), BNB Smart Chain (BEP20), and Ethereum (ERC20). Requirements: (1) review available market solutions and recommend the optimal one for our profile - a single custodial platform for all three networks or a combination of separate tools for EVM and TRON; (2) propose a signature architecture (e.g., 2-of-3), key distribution among roles, thresholds for quick/large payments; (3) provide recommendations for key storage (hardware wallets, HSM) and procedures in case of key loss or compromise. For whom: the team administering the company's treasury with a high volume of crypto transactions. Success criterion: a ready recommended architecture with a clear implementation plan. Requirements: practical experience in implementing multisig, specifically with TRON (not just EVM), experience with specific solutions (Safe/Gnosis, Fireblocks, BitGo, Cobo, or native TRON multisig), preferably with cases of previous implementations.
