Usman U.

I build blockchain and Web3 applications, Smart contracts and Full stack products that work in production, not just in demos. Over the past 5+ years I have shipped projects for clients across the US, UK, Canada and Europe, deploying 700+ Smart contracts & 200+ Web3 Dapps across Ethereum, BNB Chain, Polygon, Solana and Base. I am 𝐓𝐨𝐩 𝐑𝐚𝐭𝐞𝐝 𝐨𝐧 𝐔𝐩𝐰𝐨𝐫𝐤 with a 100% Job Success Score, which reflects the same standard I bring to every project regardless of size. ⚙️𝐒𝐞𝐫𝐯𝐢𝐜𝐞𝐬 𝐈 𝐎𝐟𝐟𝐞𝐫⚙️ 🔗 𝐁𝐥𝐨𝐜𝐤𝐜𝐡𝐚𝐢𝐧 & 𝐖𝐞𝐛𝟑 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭: I build smart contracts, token launches, Web3 play-to-earn games, and full Dapp platforms end to end. Some of the projects I have worked on include an ETH presale platform with a fiat on ramp so buyers can purchase tokens directly with a card, a full Web3 ecosystem covering a crypto exchange, a play to earn game, voting and token reward surveys. I recently built a 3D Play to Earn game based on launching rockets to the Moon and then buying land on the Moon. You can join one of two factions, and the team with the highest land at the end of the season earns rewards. Tech stack: Solidity, ERC-20, ERC-721, Solana SPL, Ethers.js, Web3.js, Wagmi, Viem, Reown Wallet Connect. Chains: Ethereum, BNB Chain, Polygon, Solana, Base, Pulsechain, Sonic chain and more. 🖥️ 𝐅𝐮𝐥𝐥 𝐒𝐭𝐚𝐜𝐤 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭 & 𝐀𝐈 𝐀𝐮𝐭𝐨𝐦𝐚𝐭𝐢𝐨𝐧: I build complete web applications from concept to deployment, frontend and backend, so you are not juggling multiple developers for one product. Some of the products I have built include a multi tenant SaaS with role based dashboards and Stripe subscriptions, and client dashboards and internal tools for businesses across multiple industries. I also layer AI automation on top when it adds real value, chatbots, voice agents and workflow automation built with the latest APIs. Tech stack: React, Next.js, Vite, TypeScript, Tailwind CSS, Node.js, Express.js, NestJS, Python, FastAPI, REST APIs, GraphQL, WebSockets, MongoDB, PostgreSQL, Firebase, Supabase, Vercel, AWS, DigitalOcean. AI Automation: OpenAI, Anthropic Claude, Google Gemini, LangChain, Make(integromat), Vapi, ElevenLabs. 🌟𝐖𝐡𝐲 𝐜𝐥𝐢𝐞𝐧𝐭𝐬 𝐤𝐞𝐞𝐩 𝐜𝐨𝐦𝐢𝐧𝐠 𝐛𝐚𝐜𝐤🌟 Every project gets the same level of attention regardless of size. You will always know where things stand, no chasing, no radio silence. And if something is not working I will tell you before you have to ask. Ready to build something? Send me a message.
