About Andris

Andris R.Status: Offline
Full-Stack Blockchain & Web3 Developer
Mykolayiv, Ukraine - 6:09 pm local time
I'm Andris, a Full-Stack Web3 and Blockchain Developer, specializing in building secure, scalable decentralized applications across multiple ecosystems.

Since early 2022, I've been developing on Ethereum and its Layer 2 networks, writing smart contracts in Solidity. I specialize in upgradeable proxy contracts, integration with Chainlink oracles for reliable off-chain data, and implementation of various token standards. I have hands-on experience building and integrating with DEX and DeFi protocols, whether creating custom AMM mechanics or integrating with established platforms like Uniswap and PancakeSwap. I use Hardhat and Remix to ensure comprehensive test coverage and smooth deployment workflows.

Since 2023, I've also been actively developing on Sui. I work extensively with the Move programming language for writing secure, resource-oriented smart contracts, utilizing the Sui SDK for comprehensive testing and deployment workflows. I'm proficient with native Sui standards for coins, tokens, and kiosks, and have experience integrating with Sui DeFi protocols like Cetus. I leverage Sui's unique object model and parallel execution capabilities.

I build complete decentralized applications with modern full-stack technologies. On the frontend, I use Next.js and React.js with TypeScript to create responsive, user-friendly interfaces. For blockchain connectivity, I implement Ethers.js for seamless wallet integration and contract interactions, along with modern state management solutions.
