Project details
Build secure Solidity smart contracts tailored to your project.
I develop ERC-20, ERC-721, and ERC-1155 contracts with clean, maintainable code and security-focused development practices.
Whether you need a utility token, NFT collection, or custom token standard, every contract is built around your requirements. Services include testing, optimization, deployment support, and documentation.
Supported networks include Ethereum, Base, BNB Chain, Polygon, Arbitrum, and other EVM-compatible blockchains.
Contact me before ordering to discuss your project requirements.

DeFi & AI Automation Engineer, Flash Loans, MEV Bots, Smart Contract.
Great experience working with him. They delivered a secure, well-documented smart contract and implemented effective DeFi automation on time. Communication was clear, technical explanations were easy to follow, and they quickly resolved minor issues during testing. Highly recommended for complex DeFi and automation projects.

Job Success
Abuja, Nigeria - 5:28 am local time
My work spans AI agent development (Claude / Anthropic APIs, Claude Code, Claude Agent SDK, MCP tool integrations), workflow automation (n8n, Make, webhook-driven pipelines, REST/API integrations), and DeFi infrastructure (FLASH LOAN ARBITRAGE BOTS, MEV- SHIELDED EXECUTION, LIQUIDATION KEEPERS), built in Python, TypeScript, Rust, and Solidity, deployed across Ethereum, Arbitrum, Polygon, and Solana.
What I deliver:
AI agents that take real action tool use, multi-step workflows, browser automation (Playwright), CRM/API integrations, with guardrails and human-in-the-loop approval for high-impact actions
Automation systems built with n8n/Make or custom Python/TypeScript runtimes, wired to REST APIs and webhooks
Flash loan arbitrage & liquidation bots (Aave V3, Compound, Euler), MEV-aware execution with Flashbots Protect
Full-stack delivery: FastAPI/Node.js backends, React front ends, AWS deployment
Machine learning-backed decision layers where they add measurable value not just an LLM bolted onto an API call
Every system I ship is production-tested, documented, and built with clear permissions, error handling, and logging so your team can actually maintain it, I don't build things that only work 70% of the time.
If you're working on an AI agent product, an automation pipeline, or a DeFi protocol and need an engineer who can move fast without cutting corners, let's talk.
