Smart Contract Developer specializing in security-first DeFi protocols and open-source infrastructure. I build production-grade contracts with 100% test coverage standards and battle-tested security patterns.
I'm a self-taught Solidity developer with a relentless focus on security-first smart contract development. Over the past 11 months, I've shipped 45+ contracts publicly, progressing from basic storage patterns to multi-strategy DeFi vaults and overcollateralized stablecoin protocols.
My approach centers on building production-grade, battle-tested contracts with 100% test coverage standards, comprehensive Foundry testing (unit + fuzz + integration), and security patterns built from first principles. I think like an attacker to build defensive systems.
I don't just import OpenZeppelin—I rebuild security patterns from scratch to deeply understand why they exist and how they work. This foundation enables me to write contracts that are not only functional but genuinely secure.
Built 18+ contract security library with custom reentrancy guards, access control, and attack simulations
Comprehensive Foundry testing across all major projects. Unit, fuzz, and integration tests are standard
300+ consecutive days building and deploying. Small daily progress compounds into significant results
Open-source security framework with 18+ modular contracts built from scratch. Production-ready smart contract infrastructure including access control, reentrancy guards, pausability, and complete ERC20 implementations.
Multi-strategy DeFi yield vault with automated capital allocation. Supports 100+ strategies with ERC4626-inspired share mechanism, real-time APY tracking, and dynamic rebalancing. Fixed critical 9% deposit bug during development.
Decentralized overcollateralized stablecoin protocol inspired by MakerDAO. Features multi-collateral support (WETH/WBTC), health factor calculations, liquidation mechanisms with bonuses, and Chainlink oracle integration for price feeds.
Soulbound NFT reputation system built in 72-hour hackathon. Reputation-gated minting with tiered rewards (Gold/Silver/Bronze), Chainlink oracle integration for decentralized reputation verification, and 98.71% test coverage.
Provably fair lottery system powered by Chainlink VRF v2.5 for verifiable random winner selection and Chainlink Automation for automated draws. Event-driven architecture with comprehensive test coverage.
Gas-optimized storage contract using packed structs, bytes16 fields, and custom errors. Designed for minimal storage gas with clean Foundry tests. Deployed and verified on Sepolia testnet.
A comprehensive learning journey from basic storage contracts to complex DeFi protocols. 20+ contracts covering governance, NFTs, security, and gas optimization patterns.
