Hossein S.

I'm a results-driven Blockchain Developer and AI Engineer with hands-on experience designing and deploying secure, scalable decentralized systems. My expertise spans smart contract development, real-time AI integration, and data science, backed by a strong academic foundation from Bournemouth University (MSc in Data Science & Artificial Intelligence, 2024–2025). I recently completed a cutting-edge project where I built a Solana-based decentralized vehicle trust management system, integrating smart contracts (Rust/Anchor) with a Flask backend, React frontend, and real-time simulation using SUMO. The system featured advanced components such as Zero-Knowledge Proofs (ZKPs), Cross-Program Invocations (CPI), on-chain behavior validation, and blockchain access control. On the AI side, I developed a trust scoring model using Python, Pandas, and Scikit-learn, leveraging behavior recognition, anomaly detection, and predictive analytics to classify vehicles as trusted or malicious. I also worked with federated learning, reinforcement learning, and real-time data pipelines to ensure the system was privacy-preserving and adaptable to live environments. 🔧 Core Skills & Tools Smart Contracts & Blockchain Solana, Ethereum, Anchor, Rust, Solidity, Web3.js, ZKP, PDA, CPI, Wallet Auth AI, ML & Data Science TensorFlow, PyTorch, Scikit-learn, Federated Learning, Predictive Analytics, Reinforcement Learning, Model Evaluation Web & Backend Development React, Next.js, Flask, Node.js, Django, REST APIs, Socket.IO DevOps & Infrastructure Docker, Kubernetes, CI/CD, Git, Cloud Deployment (AWS, Heroku) Data Engineering Pandas, NumPy, MySQL, MongoDB, Neo4j, Data Preprocessing, ETL Pipelines
