I'm a US-based engineer who builds infrastructure — cleanly, professionally, and without unnecessary noise. Clients come to me when they need technical depth, full ownership, and a partner who understands both execution and long-term architecture. I work quietly, move fast, and think clearly. Over the last few years, I’ve engineered over 50 blockchain systems — from Solana launchpads and Ethereum bundling platforms to custom liquidity bots, presale protocols, and real-time trading automation. When I work on something, I don’t decorate it — I make it dependable. 🔹 𝐖𝐡𝐚𝐭 𝐈 𝐕𝐚𝐥𝐮𝐞 𝐢𝐧 𝐄𝐯𝐞𝐫𝐲 𝐏𝐫𝐨𝐣𝐞𝐜𝐭 🔸 𝐏𝐫𝐞𝐝𝐢𝐜𝐭𝐚𝐛𝐢𝐥𝐢𝐭𝐲 Good engineering isn’t dramatic. You should always know where things stand — what's built, what's next, and why. 🔸 𝐑𝐞𝐬𝐩𝐞𝐜𝐭 This is a collaboration. I treat your product with the same care I’d give my own. I don’t disappear, I don’t make excuses, and I don’t deliver anything half-ready. 🔸 𝐃𝐞𝐩𝐭𝐡 I’ve seen what breaks in production. I’ve seen what scales and what rots. I bring that clarity into every decision — from code structure to endpoint design. 🔸 𝐐𝐮𝐢𝐞𝐭 𝐂𝐨𝐧𝐟𝐢𝐝𝐞𝐧𝐜𝐞 I don’t try to look impressive. I focus on making your system stronger — technically, operationally, and practically. 🔹 𝐁𝐥𝐨𝐜𝐤𝐜𝐡𝐚𝐢𝐧 & 𝐒𝐦𝐚𝐫𝐭 𝐂𝐨𝐧𝐭𝐫𝐚𝐜𝐭 𝐒𝐲𝐬𝐭𝐞𝐦𝐬 ★ 𝐄𝐭𝐡𝐞𝐫𝐞𝐮𝐦 💨 Smart Contracts: ERC-20, ERC-721, ERC-1155, Solidity, Hardhat, Ethers.js, Web3.js 💨 Flashbots MEV Bundling → eth.bundler.gritsmart.io 💨 Token Launchpads, NFT drops, Staking logic, Presale contracts 💨 Frontend + Backend for Ethereum DeFi & dApps ★ 𝐒𝐨𝐥𝐚𝐧𝐚 💨 Rust + Anchor Framework 💨 Jito Bundling → sol.bundler.gritsmart.io 💨 SPL Token infrastructure 💨 Pump.fun bots, liquidity automation, transaction routing 💨 Memecoin deployment with real-time trading and farming contracts ★ 𝐎𝐭𝐡𝐞𝐫 𝐂𝐡𝐚𝐢𝐧𝐬 & 𝐓𝐨𝐨𝐥𝐬 💨 Tron, XRPL, Sui 💨 Telegram Bots: snipe tools, volume alerts, trade triggers 💨 Wallet Support: Metamask, Phantom, WalletConnect 🔹 𝐅𝐮𝐥𝐥 𝐒𝐭𝐚𝐜𝐤 𝐄𝐧𝐠𝐢𝐧𝐞𝐞𝐫𝐢𝐧𝐠 & 𝐀𝐮𝐭𝐨𝐦𝐚𝐭𝐢𝐨𝐧 ★ 𝐅𝐫𝐨𝐧𝐭𝐞𝐧𝐝 ▪ React.js, Next.js (with SSR) ▪ TypeScript, TailwindCSS ▪ UI/UX with Framer Motion and animated state logic ★ 𝐁𝐚𝐜𝐤𝐞𝐧𝐝 ▪ Node.js, Express ▪ GraphQL + RESTful APIs ▪ Real-time Webhooks, Transaction Indexers, Data Sync Engines ★ 𝐈𝐧𝐟𝐫𝐚𝐬𝐭𝐫𝐮𝐜𝐭𝐮𝐫𝐞 & 𝐈𝐧𝐝𝐞𝐱𝐢𝐧𝐠 ▪ PostgreSQL, MongoDB, Redis ▪ Elasticsearch + Lucene ▪ Docker, Nginx, GitHub Actions, PM2 ▪ Linux VPS Deployment (PowerVPS stack) ★ 𝐒𝐞𝐜𝐮𝐫𝐢𝐭𝐲 + 𝐀𝐮𝐭𝐡 ▪ JWT, OAuth2, Firebase Auth ▪ Wallet-based token gating ▪ Admin layers with IP, session & rate limit control 🔹 𝐃𝐞𝐞𝐩 𝐒𝐞𝐚𝐫𝐜𝐡 & 𝐈𝐧𝐝𝐞𝐱𝐢𝐧𝐠 𝐖𝐨𝐫𝐤 Most developers don’t go this deep — but I’ve built full Lucene-powered search engines into token ecosystems. 💨 Elasticsearch + Lucene for transaction metadata 💨 Integrated into MongoDB and MySQL 💨 Real-time indexing for performance-critical systems 🔹 𝐒𝐲𝐬𝐭𝐞𝐦𝐬 𝐇𝐨𝐬𝐭𝐢𝐧𝐠 & 𝐎𝐩𝐞𝐫𝐚𝐭𝐢𝐨𝐧𝐚𝐥 𝐒𝐞𝐭𝐮𝐩 𝐋𝐢𝐧𝐮𝐱 𝐬𝐞𝐫𝐯𝐞𝐫 𝐚𝐮𝐭𝐨𝐦𝐚𝐭𝐢𝐨𝐧 💨 VPS hosting, domain setup, and DNS routing 💨 Telegram bot deployment with uptime monitoring 💨 Reverse proxy with Nginx for secure routing 🔹 𝐖𝐡𝐚𝐭 𝐖𝐨𝐫𝐤𝐢𝐧𝐠 𝐖𝐢𝐭𝐡 𝐌𝐞 𝐅𝐞𝐞𝐥𝐬 𝐋𝐢𝐤𝐞 You’ll never have to guess what’s going on. You’ll know your system is built with structure, not chaos. You’ll have an engineer who treats your product like infrastructure — not a quick task. I believe in professionalism through precision, not pressure. If I say I can do it, it means I already know how. I don’t say more than needed, and I don’t promise what I can’t control. If you’re a serious founder, builder, or startup needing a long-term system — not just a temporary patch — I’m here to work with you and I only work on upwork. 𝐔𝐧𝐢𝐭𝐞𝐝 𝐒𝐭𝐚𝐭𝐞𝐬 𝐉𝐨𝐫𝐝𝐚𝐧
