About Muhammad
AI + Web3 Engineer | Smart Contracts + AI Agents | Hackathon Winner
Jakarta, Indonesia - 12:41 am local time
I am Rama, and I help Web3 founders and crypto-AI startups ship production smart contracts, dApps, and AI agents - not demos.
I won 1st place globally at the CoinGecko MCP Hackathon for GeckoPilot (an AI-powered crypto analyst, beat hundreds of submissions, 2,000+ community votes), 2nd place at Ninja API Forge for InjectiveIQ (AI market intelligence on Injective), 2nd place at BlockDevID for Waffle, plus a Lisk Spark grant and Top 10 Builders Challenge finish for Sugar. I'm currently an Ambassador for the Arbitrum Foundation, supporting builders on Layer 2.
What I can build for you:
- Smart contracts in Solidity (Foundry, OpenZeppelin, gas-optimized, fully tested)
- Full-stack dApps with Next, wagmi, viem, and RainbowKit
- AI agents for crypto data, portfolio analytics, or trading workflows (MCP-based)
- ERC-20/721/1155 token systems, NFT marketplaces, on-chain credentials
- DeFi launchpads, crowdfunding platforms, vesting/escrow contracts
- Multi-chain integrations: I've shipped on Ethereum, Arbitrum, Solana, Sui (Move), Stellar (Soroban), Avalanche, Injective, Lisk, EDU Chain, Cosmos, and more
Stack I work with daily:
- Languages: Solidity, TypeScript, JavaScript, Rust, Move, Yul, Golang
- Smart contracts: Foundry, Hardhat, OpenZeppelin, Chainlink
- Frontend: Next, React, Vue, Nuxt, TailwindCSS, ShadCN, Framer Motion
- Web3 libs: ethers, viem, wagmi, RainbowKit, Solana web3, Mysten dApp Kit
- Backend: Node, NestJS, Express, GraphQL, PostgreSQL, MongoDB, Redis
- Infra: Docker, Vercel, AWS, CI/CD, Git
Open source impact: I maintain 84+ public repos with 2,400+ GitHub followers and 2,500+ stars across Web3 automation tools, smart contract templates, and developer utilities used by the broader Web3 community. I founded Happy Cuan Airdrop, a 30,000-member community for Indonesian Web3 builders.
Selected shipped projects:
- GeckoPilot - AI crypto analyst (1st place CoinGecko MCP Hackathon 2025)
- InjectiveIQ - AI market intelligence API on Injective (2nd place Ninja API Forge 2026)
- Sugar - Web3 streaming with on-chain payments (Lisk Spark grant + Top 10 Builders Challenge)
- Waffle - Decentralized reputation platform (2nd place BlockDev ID 2025)
- Credura - On-chain credentials (ERC-20/721/1155 + IPFS, Foundry + Next)
- GoFundingFun - Crowdfunding launchpad with milestone vesting (Top 150 of 9,000+ at EDU Chain)
- Tamago-Sui - Sui Move blockchain game with dynamic fields and time-based logic
I'm new to Upwork but not new to engineering. To build my reputation here my starting rate is intentionally below market. I'd rather earn 5 great reviews fast than chase top rates day one.
If your project sounds like a fit, send me a message. I usually reply within a few hours during my working day, and I'm happy to jump on a 15-minute call to scope it out.
