What I'm looking for

I'm open to international remote, contract, freelance, part-time, or full-time work as a Smart Contract Technical Lead, Senior Solidity Engineer, Blockchain Security Engineer, Technical Consultant, or project-based blockchain specialist.

I've built and deployed Solidity smart contracts for the CrowdSwap DeFi DEX ecosystem, supporting swaps and cross-chain functionality across EVM networks and Layer 2 environments.

At SmartThinking, I lead hands-on smart contract delivery spanning EVM architecture, security workflows, AI-assisted analysis, automated threat detection, and Web3 backend integrations.

My work combines Solidity, Hardhat, OpenZeppelin, Tenderly, Etherscan, Python, Django, TypeScript, and Node.js to develop, review, debug, test, and deploy production blockchain systems.

Alongside blockchain work, I've led software architecture, database design, code review, and distributed engineering teams across long-running enterprise and backend projects.
