Skills
Work Experience
Senior Smart Contract Engineer
Protofire
Aug 2024 — Present
Contributed to the LYS Protocol by architecting lending mechanics, integrating multi-protocol EigenLayer restaking, and building Go-based back-end services. Led end-to-end Solidity smart contract development for Chain.Love (Web3 infrastructure marketplace), implementing on-chain SLAs, decentralized monitoring contracts, and automated load balancing logic. Engineered an EigenLayer AVS solution with automated CI/CD pipelines; integrated SSV Network distributed operators, Balancer/Curve pool types, and restaking protocols into a multi-chain hot wallet infrastructure, reducing setup time by 40%.
Smart Contract Audit Fellowship
Nethermind
Jul 2024 — Sept 2024
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. Conducted internal security audits producing detailed audit reports with severity-ranked findings and remediation recommendations. Studied smart-contract security patterns using Foundry fuzz testing, gRPC debugging, and reentrancy/flash-loan analysis.
Senior Smart Contract Engineer
SoftConstruct
Sept 2023 — Aug 2024
Architected and deployed the FTN native-coin staking platform, designing token mechanics, reward distribution, and upgradeable contracts with OpenZeppelin proxies. Led comprehensive testing strategy using Foundry achieving 95%+ test coverage. Deep hands-on expertise with liquid staking protocols (Lido, Rocket Pool, StakeWise). Developed lending protocol from scratch and implemented complex fixed-point arithmetic and interest rate models in Solidity.
Smart Contract Engineer
Codeex
Nov 2021 — Sept 2023
Designed, developed, and deployed 20+ production smart contracts for DeFi primitives (AMMs, staking, yield farming, lending) on EVM-compatible chains. Conducted rigorous code reviews and gas optimizations, reducing average transaction costs by 20–30%. Built comprehensive test suites with Foundry. Integrated Alpaca Finance yield strategies into staking platform. Owned end-to-end smart contract lifecycle for a full DeFi staking ecosystem.
Mobile Application Developer
XamLab
Jul 2018 — Jun 2019
Participated in architectural discussions and created REST APIs using C# and .NET. Implemented C#.Net services using MVVM architecture and SOLID principles to streamline backend integration for mobile apps.
