Solidity Engineerspecializing in Real World Asset (RWA) tokenization and DeFi infrastructure.
For nearly 5 years at **RealT**, I designed and deployed the complete smart contract architecture for a SEC-regulated real estate platform: security tokens, cross-chain bridges, vaults, yield distribution, and subgraph infrastructure on The Graph. All my production contracts underwent external security audits that I managed end-to-end.
Before RealT, I contributed atTokenyto the ONCHAINID on-chain identity protocol and the migration of smart contracts to the EIP-1822 standard.
I also offer pre-audit security reviews. Before launching an external audit, a thorough review helps identify obvious vulnerabilities, optimize code, and prepare technical documentation.
Result:a faster, cheaper audit, and more robust code. Having managed several external audit cycles on SEC-regulated contracts, I know exactly what auditors are looking for.
I can also deliver **complete projects from A to Z**. I work with a trusted frontend team, allowing me to handle a project from smart contract architecture to a final production interface.
What I can bring to your project:
- End-to-end smart contract architecture design
- Security tokens and regulatory compliance
- Cross-chain bridges and DeFi protocols
- Vaults, yield mechanisms, and distribution
- Pre-audit security reviews and external audit management
- On-chain indexing with The Graph
- Full-stack delivery with frontend integration
Available for long-term engagements on ambitious projects, remotely.
