⭐ Top Rated - Top 10% Talent on Upwork | 🕒 1,000+ hours on Upwork | ✅ 10+ years of experience I help founders and teams build blockchain products that need more than just smart contract development. My focus is on end-to-end Web3 product execution, smart contracts, dApp architecture, backend systems, frontend development, wallet integrations, and production-ready user flows. I work on blockchain applications that need to be usable, scalable, and commercially workable, whether that is a DeFi platform, a staking product, a tokenized workflow, or a full Web3 application. A lot of blockchain projects struggle not at the idea stage, but at the implementation layer. The contracts may be written, but the product still feels incomplete because the frontend flow, backend support, wallet interactions, and operational usability are weak. That is where I usually add value. I work across the blockchain and full-stack layers to help turn technical concepts into working products. Alongside blockchain development, I also bring strong full-stack product execution experience. That means I can contribute not only to the smart contract side, but also to the APIs, backend architecture, dashboards, user-facing applications, and integration logic required to make the platform function properly as a complete product. ✅ Core areas I work in: - Smart contracts and protocol logic - dApp development and Web3 frontend integration - DeFi platforms, staking systems, vaults, and rewards logic - ERC-20, ERC-721, and ERC-1155 token contracts - Wallet connectivity and transaction flows - Backend systems for blockchain-based products - Admin dashboards and operational interfaces - Full-stack development for Web3 applications - Tokenization-related product architecture - Feature delivery and end-to-end product buildout ✅𝐂𝐮𝐬𝐭𝐨𝐦 𝐒𝐨𝐟𝐭𝐰𝐚𝐫𝐞 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭: - Web Apps: Custom web solutions, e-commerce platforms, MLM systems, and landing pages. - Mobile Apps: Native and cross-platform iOS and Android apps using Flutter and React Native. - Telegram Bots: Custom Telegram bots, including crypto-related automation and tools. ✅ 𝐓𝐞𝐜𝐡 𝐒𝐭𝐚𝐜𝐤 𝐏𝐫𝐨𝐟𝐢𝐜𝐢𝐞𝐧𝐜𝐲: - AI Tools: TensorFlow, OpenAI, GPT, NLTK, Rasa, Spacy - Blockchain: Solidity, Hardhat, Foundry, OpenZeppelin, Ethers.js, Web3.js - Frontend: ReactJS, NextJS, VueJS, EmberJS, ASP.Net Core & MVC - Backend: NodeJS (ExpressJS, NestJS), Python, C# - Mobile Development: Flutter, React Native - Database Management: MongoDB, PostgreSQL I am comfortable contributing at different levels depending on what the project needs — smart contracts, dApp integration, backend implementation, frontend development, architecture support, feature delivery, or complete product buildout. So whether you need a blockchain developer for a core Web3 feature, or a full-stack developer who can handle the product around the blockchain layer as well, I can support both sides in a practical and execution-focused way. If your project needs someone who understands both the blockchain side and the full-stack product side of Web3 development, I’d be happy to discuss it.
