Stephan Rayan

I can:

✅ Develop secure smart contracts (Solidity, Hardhat, Foundry) for:

· Asset tokenization (real estate, commodities, art).

· DeFi protocols (staking, lending, yield farming).

· NFTs and marketplaces (ERC-721, ERC-1155).

· Compliant solutions (KYC/AML, ERC-1400).

✅ Create autonomous AI agents (Python, Rasa NLU, Hermes Framework) for:

· Automating repetitive tasks (market research, alerts, trading).

· Developing multilingual chatbots (FR/AR/EN) for customer support or data analysis.

· Integrating AI models (LangChain, transformers) to generate content or analyze trends.

✅ Build DApps and Web3 interfaces (React.js, Next.js, ethers.js):

· Integration with MetaMask, WalletConnect, and other wallets.

· Dashboards for visualizing on-chain data (The Graph, Alchemy).

· SEO-friendly websites for crypto projects.

🔹 What sets me apart:

· Web3 + AI Expertise: I combine blockchain and artificial intelligence for innovative solutions (e.g., autonomous agents for DeFi, crypto chatbots).

· Turnkey Approach: I handle everything, from smart contracts to frontend integration, including security audits and documentation.

· Flexible Payments: I work in crypto (USDT, BTC) or fiat, according to your preferences.

🔹 My ideal clients:

· Crypto startups (DeFi, NFT, tokenization) that need a responsive and technical developer.

· Fintech companies looking to integrate blockchain or AI solutions.

· Web3 projects in the launch or scaling phase (e.g., token launch, DApp creation).

🔹 Typical deliverables:

· Audited and deployed smart contracts (Ethereum, Polygon, Arbitrum).

· Ready-to-use autonomous agents (with documentation and support).

· Responsive and secure DApps (React + Web3.js/ethers.js).

· Multilingual chatbots (FR/AR/EN) for support or data analysis.
