  • SRC Ecosystem
    Blockchain Lead & Developer
    SRC Ecosystem
    May 2026 - Current (7 months)
    • Lead smart contract and blockchain engineering for the $SRC Ecosystem, a trade-finance platform running on its own
    dedicated subnet on the XDC Network that tokenizes real-world trade assets — invoices, bills of lading, and warehouse
    receipts — into on-chain instruments.
    • Deployed and operate the dedicated SRC subnet on the XDC Network, owning network configuration, validator setup, and
    the smart contract layer underpinning the platform.
    • Architect milestone-based escrow and settlement contracts that automatically release funds on verified trade events,
    reducing counterparty risk and removing intermediary dependence in cross-border trade.
    • Design RWA tokenization and on-chain verification logic aligned
  • Protofire
    Smart Contract Engineer
    Protofire
    Aug 2024 - May 2026 (1 year 10 months)
    • Contributed to the LYS Protocol — designed lending mechanics, integrated multi-protocol EigenLayer restaking, and built
    Go-based services for seamless protocol data flow.
    • Led end-to-end Solidity development for Chain.Love (Web3 infrastructure marketplace): implemented on-chain SLAs,
    decentralized monitoring contracts, automated load balancing, and optimized DeFi flows.
    • Engineered an EigenLayer AVS solution with automated CI/CD on GitHub; integrated SSV Network operators,
    Balancer/Curve pools, and restaking protocols (AAVE v3, Compound, Frax, StakeWise, Rocket Pool) into a multi-chain
    hot wallet infrastructure — redu
  • Nethermind
    Smart Contract Auditor
    Nethermind
    Jul 2024 - Sep 2024 (3 months)
    • Performed security reviews and internal audits of production DeFi and restaking protocols (EigenLayer, Swell,
    Symbiotic) on Ethereum and Solana.
    • Applied formal verification tooling (Certora Prover, Halmos) to verify protocol invariants; explored ZK proof fundamentals
    for smart contract applications.
    • Produced detailed audit reports with severity-ranked findings and remediation recommendations; leveraged fuzz testing,
    gRPC debugging, and reentrancy/flash-loan analysis to identify critical vulnerabilities.
  • SoftConstruct
    Smart Contract Engineer
    SoftConstruct
    Sep 2023 - Aug 2024 (1 year)
    • Architected and deployed the FTN native-coin staking platform — designed token mechanics, reward distribution, and
    upgradeable contracts using OpenZeppelin proxies.
    • Implemented complex fixed-point arithmetic and interest rate models in Solidity for gas-optimized DeFi lending
    calculations.
    • Led comprehensive Foundry testing strategy (unit, fuzz, invariant, fork tests) — achieving 95%+ test coverage and
    preventing critical pre-deployment bugs.
    • Deep hands-on implementation of liquid staking protocols (Lido, Rocket Pool, StakeWise): liquid staking derivative
    tokens, withdrawal queues, and slashing protection logic.
  • Codeex Software Development Company
    Smart Contract Engineer
    Codeex Software Development Company
    Nov 2021 - Sep 2023 (1 year 11 months)
    • Designed, developed, and deployed 20+ production smart contracts for DeFi primitives (AMMs, staking, yield farming,
    lending) on EVM-compatible chains.
    • Reduced average transaction costs by 20–30% through assembly optimizations, storage slot packing, and batch
    operations.
    • Integrated Alpaca Finance yield strategies into staking platform; owned full smart contract lifecycle (design → audit →
    deployment → maintenance) for a complete DeFi staking ecosystem.
    • Deep expertise in EVM internals, AMM/MasterChef staking algorithms, Proxy patterns, and transaction debugging with
    Phalcon and Tenderly.
  • freelance
    Solidity developer
    freelance
    Nov 2019 - Nov 2021 (2 years 1 month)
    Smart Contract Engineering: Designed, unit-tested, and deployed secure ERC-20 and ERC-721 smart contracts across Ethereum Mainnet and testnets (Rinkeby, Kovan) using Truffle, Remix, and Solidity.

    Security & Gas Optimization: Identified and patched access control and reentrancy vulnerabilities while optimizing storage layouts and compiler settings to minimize user gas costs.

    Full-Stack dApp Integration: Built interactive Web3 frontends and seamlessly connected smart contracts to UI flows using React.js, Web3.js, Ethers.js, and Metamask integration.
