Experience
- Built and deployed payroll smart contracts for PayNova on EVM-compatible chains, handling on-chain disbursement logic.
- Researched W3C DID standards and Verifiable Credentials to design self-sovereign identity layers for Web3 payroll.
- Owned full client-side of PayZoll for production, integrating wallet connectivity and building on Stellar's payment rails.

- Architected and fully implemented ERC-3643 (T-REX) fully on-chain for compliant RWA issuance, engineering identity-bound transfer controls, modular compliance enforcement, and upgrade-safe contract systems.
- Researched ERC-3643 and ERC-7518 to design interoperable, regulation-aligned RWA token primitives across institutional-grade on-chain frameworks.
- Engineered a chain-agnostic RWA execution layer across Mantle, OneChain, Creditcoin, and Stellar, abstracting settlement, custody logic, and lifecycle orchestration into unified cross-chain infrastructure.
- Built cron-driven backend automation for liquidation monitoring and deterministic time-weighted yield distribution aligned with on-chain state transitions.
- Won 3 hackathons competing under this project banner.
