I work as a Full Stack Developer, Web3 Developer and Blockchain Developer building production-ready applications that connect business logic with blockchain infrastructure. As a Web3 Developer, I focus on wallet integrations, smart contract interactions, and scalable dApp architecture. As a Blockchain Developer, I design and implement secure, efficient systems on top of modern blockchain networks. As a Full Stack Developer, I ensure everything works end-to-end, from frontend to backend, clean, scalable, and maintainable. As a Web3 Developer, Blockchain Developer, and Full Stack Developer, I’ve worked on real-world products involving NFT platforms, DeFi systems, and exchange-related applications. My main specialization as a Web3 Developer and blockchain developer is building integrations between applications and blockchain networks, including wallet connections, contract execution, and real-time data handling. I work deeply with blockchain infrastructure, ensuring applications behave reliably under real user conditions. The projects I’ve worked on include: - NFT platforms as an experienced nft developer: landing-based apps, SPA and multi-page applications, NFT marketplaces, hybrid exchange systems, and Uniswap forks - Smart contract integrations as a Blockchain Developer: contract interaction using web3 and ethers libraries, handling transactions, events, and contract state as a smart contract engineer - Wallet integrations as a Web3 Developer: Metamask connections, custom Web3 context implementations, and secure interaction flows - Backend systems as a Full Stack Developer: building services with Node.js and TypeScript, working with MongoDB (Mongoose), PostgreSQL (Supabase), and Prisma for NFT data and application logic - Blockchain data querying as a Blockchain Developer: using Apollo Client with Uniswap subgraphs to fetch and process on-chain data efficiently - Gas optimization as a Web3 Developer: creating services that fetch gas price predictions and apply them to outgoing transactions - Exchange integrations as a Full Stack Developer: working with Binance API, order creation, and financial workflows As a Web3 Developer and Blockchain Developer, I have strong experience working with solidity, including creating ERC20 mintable tokens and handling contract deployment pipelines with Hardhat. As a Blockchain Developer, I have also handled migration of NFT systems from Ethereum to non-Ethereum environments, adapting logic, contracts, and integrations accordingly. As a Web3 Developer, I ensure compatibility across different chains and environments. On the frontend, as a react developer and web developer, I build modern, responsive interfaces using React, Next.js, and TypeScript. I’ve worked with Material UI, styled-components, Bootstrap, SCSS, and CSS modules, ensuring clean UI systems and maintainable code. On the backend, as a Full Stack Developer, I design APIs, manage data flows, and ensure consistency across distributed systems. I’ve also worked with state management (Redux, Redux Toolkit, redux-localstorage-simple), data layers (Prisma, MongoDB, PostgreSQL), and tooling (ESLint, Prettier), ensuring code quality and long-term maintainability across projects. As a Web3 Developer, Blockchain Developer, and Full Stack Developer, I focus on performance, reliability, and scalability. Many blockchain products fail not because of the idea, but because of weak implementation. As a Web3 Developer, I make sure integrations with wallets and smart contract systems are stable and predictable under real usage. As a Blockchain Developer, I focus on transaction correctness, contract behavior, and data consistency. As a Full Stack Developer, I ensure the entire system behaves correctly across frontend, backend, and infrastructure. In addition, as a Web3 Developer, I work on improving UX around blockchain interactions, reducing friction for users interacting with nft platforms and contract-based systems. As a Blockchain Developer, I focus on writing efficient and maintainable solidity code. As a Full Stack Developer, I connect all layers into usable, scalable products. Beyond blockchain, my broader experience as a web developer, wordpress developer, and mobile app developer allows me to approach projects from a full product perspective, ensuring usability, performance, and scalability in real-world conditions. I continuously improve as a Web3 Developer, Blockchain Developer, and Full Stack Developer, staying up to date with modern tools, frameworks, and best practices across blockchain and web development. If you’re looking for a Web3 Developer, Blockchain Developer, or Full Stack Developer to build NFT platforms, smart contract systems, or scalable applications connected to blockchain, I can help deliver a reliable, production-ready solution.
