Mateo Kova — Web3 & Full-Stack Developer | EVM & Solana Smart Contracts, DeFi, AI Agents
I’m a seasoned Web3 and full-stack developer with deep experience building scalable decentralized applications, smart contracts, and crypto-native platforms. Over the past few years, I’ve helped ship production-ready systems for DeFi protocols, NFT marketplaces, staking platforms, cross-chain bridges, and AI-powered trading agents.
My technical toolkit includes Solidity, Node.js, React, TypeScript, Wagmi, Viem, and Web3.js, along with development tools like Hardhat, Foundry, and Tenderly. I’ve deployed and audited smart contracts across multiple EVM-compatible blockchains including Ethereum, Polygon, Cronos, and BSC, with a strong focus on gas efficiency, security, and maintainability.
I’ve contributed to high-impact projects like:
- ChainSwap – A cross-chain DeFi protocol using Chainlink CCIP and Circle’s CCTP.
- SwellNetwork – Liquid restaking infrastructure on Ethereum.
- Ebisusbay – The #1 NFT marketplace and DEX on Cronos.
- MAYA Token & Agents – AI-powered crypto assistant with integrated trading, wallet management, and social media automation.
I bring a startup mindset — fast iteration, clean architecture, and a commitment to shipping quality code that delivers real utility. I'm passionate about the intersection of AI, DeFi, and user experience, and love working on systems that simplify the way people interact with blockchain technology.
Currently, I’m focused on building Web3 infrastructure and AI-powered agents that combine real-time data, automation, and crypto-native actions. Whether it’s building smart contract ecosystems or integrating AI with decentralized protocols, I thrive in high-impact environments where innovation meets execution.
Let’s build the future of Web3 — one smart contract at a time.
