Senior Blockchain Architect | Smart Contract Security Researcher | Full-Stack Web3 Engineer Web3 Security Expert | High-Performance Backend Architect | Top-Rated Developer | 100% Commitment to Protocol Safety 👨‍💻 About Me I am a Senior Blockchain Engineer and Web3 Security Researcher with 3+ years of experience specializing in architecting high-performance, fault-tolerant decentralized systems. I bridge the gap between secure on-chain logic and institutional-grade backend infrastructure. I don’t just write smart contracts—I engineer systems for peak performance and military-grade security. Whether it is auditing high-value DeFi protocols or architecting microservices for NatWest Group, my work translates to measurable improvements in system safety, gas efficiency, and throughput. ➡ Why Clients Hire Me • Proven Security Track Record: Identified 20+ critical vulnerabilities in production-grade protocols. Ranked Weekly #347 on Code4rena and #856 on Sherlock global leaderboards. • Institutional-Grade Engineering: Currently architecting microservices from scratch at NatWest Group, owning the complete lifecycle from design to cloud deployment. • Gas & Performance Mastery: Engineered gas optimizations that reduced execution costs by up to 60%. Boosted backend system throughput by 200% using advanced concurrency models. • Academic & Research Authority: IEEE-published author on blockchain architecture, achieving a 100x faster resolution time compared to traditional systems. • Mainnet Success: Successfully launched Middle Earth AI on Solana Mainnet, securing over $100K in TVL with 500+ active players. ➡ My Services 1️⃣ Smart Contract Auditing & Security Analysis Comprehensive audits for Solidity and Rust (Anchor) codebases. I identify reentrancy, complex logic errors, and economic exploits using Foundry, Hardhat, and custom fuzzing suites. 2️⃣ DeFi & Web3 Protocol Development End-to-end architecture for token issuance, staking vaults (ERC-4626), reward distribution, and Merkle-based airdrops. Expert in gas-optimized DeFi primitives and account abstraction (ERC-4337). 3️⃣ High-Performance Backend & API Engineering Building resilient microservices using Python (FastAPI) and Go to bridge off-chain workflows with on-chain data. Specializing in high-volume data ingestion and 3x API latency reduction. 4️⃣ Full-Stack DApp Integration Seamless integration of secure contracts with responsive React/Next.js frontends using Ethers.js and Web3.js for a cohesive user experience. ➡ Tech Stack Expertise 🧠 AI & Agentic Development: • LLMs & Interfaces: Gemini 1.5 Pro, ChatGPT (GPT-4o), Claude 3.5 Sonnet, OpenRouter. • Agentic Tools: AntiGravity, OpenClaw, LangChain, LlamaIndex, AutoGPT. • AI Dev Environment: Cursor, GitHub Copilot, Ghostwriter. • AI Infrastructure: Vector Databases (Pinecone, Weaviate, Milvus), OpenAI API, Anthropic API. ⚙️ Backend & Systems: • Languages: Solidity, Yul, Rust, Python, Go, Java, SQL, C++, TypeScript. • Frameworks: FastAPI, Django, Flask, Spring Boot, gRPC, Protobuf, Node.js. • Performance: Celery, Redis, RabbitMQ, Kafka, Multithreading/Concurrency. ⛓️ Blockchain & Security: • Security Tools: Foundry, Hardhat, Slither, Echidna, Mythril, Surya, SolidityScan, Manticore. • Frameworks & Libraries: Anchor (Solana), OpenZeppelin, Ethers.js, Web3.js, Web3.py, Tenderly. • Standards: ERC-20, ERC-721, ERC-1155, ERC-4626 (Vaults), ERC-4337 (AA), ERC-6551. 🌐 Frontend & UI: • React.js, Next.js, Redux, Tailwind CSS, Shadcn/UI, Framer Motion, Three.js. 📊 Data, Cloud & DevOps: • Databases: PostgreSQL, MongoDB, MySQL, OracleDB, Cassandra, Elasticsearch. • Infrastructure: Docker, Kubernetes, Terraform, Ansible, CI/CD (GitHub Actions, Jenkins). • Cloud Platforms: Google Cloud (GCP), AWS, Azure, Vercel, Render.
