⚙️ 10+ years building production-ready AI systems & secure blockchain applications
I’m a Senior AI Engineer, Machine Learning Engineer, and Blockchain Developer with 10+ years of hands-on experience building production-ready AI systems and secure blockchain applications.
I work with startups and businesses that need real implementations, not experiments — from ChatGPT-powered AI automation and custom ML models to Solidity smart contracts and Web3 integrations.
📌 What I actually do day-to-day
💻 AI / Machine Learning
• ChatGPT & OpenAI API integrations (custom chatbots, assistants, automation)
• LLM systems: RAG, vector databases (Pinecone, FAISS), embeddings
• NLP, document intelligence, and computer vision solutions
• Model training, evaluation, and deployment (TensorFlow, PyTorch)
• Python-based ML pipelines and backend APIs (FastAPI, Django)
🔗 Blockchain / Web3
🔹 Smart contract development with Solidity (ERC-20, ERC-721, ERC-1155)
🔹 NFT utilities, DeFi logic, staking, and tokenized systems
🔹 Web3 integrations (Web3.js, Ethers.js, MetaMask)
🔹 Secure on-chain / off-chain system design and best practices
📍 How I work
🟦 clarify the problem first
🟦 design a clean, scalable architecture
🟦 build, test, and deploy systems that hold up in production
I’ve spent years working on AI/ML systems and blockchain platforms where reliability, security, and maintainability matter.
🛠 Tech stack (core)
• AI / ML: Python, ChatGPT, OpenAI API, LLMs, RAG, TensorFlow, PyTorch, NLP
• Blockchain: Solidity, Smart Contracts, Web3.js, NFTs, DeFi, EVM
• Backend: FastAPI, Django, REST APIs
• Infrastructure: Docker, Cloud deployment, production monitoring
📨 Who should contact me
• You need an AI Engineer or Machine Learning Engineer who understands production
• You need a Blockchain / Solidity Developer who writes secure contracts
• You want one senior engineer who can connect AI + Web3 properly
If that sounds like your project, send me a short description and I’ll respond with a clear technical plan and next steps.
