Collaborated closely with the lead developer at Tecmie to develop bbnpolls, an innovative on-chain market and event prediction platform, demonstrating a commitment to pushing the boundaries of blockchain applications. Implemented the ERC721A standard in bbnpolls, reinforcing a consistent and standardized approach to tokenization within the project's framework. Developed and thoroughly tested five smart contracts for bbnpolls, ensuring the reliability and security of the platform's on-chain functionalities. Led the development as the lead smart contract developer at Tecmie for Odele, an on-chain advertising and promotions platform tailored for creators and consumers, showcasing leadership and expertise in blockchain-driven marketing solutions. Engineered a mathematically precise ERC20 token for Odele, serving as both rewards for creators and a secure payment method for consumers, exemplifying a strategic and innovative approach to blockchain-based incentives. Developed and rigorously tested four smart contracts for Odele, ensuring the reliability and robustness of the on-chain advertising and promotions platform. Directed the smart contract development for Wyre, an on-chain payroll system designed for seamless single, instant, future, and batch payments, showcasing leadership in crafting efficient and versatile blockchain-based financial solutions. Applied the ERC20 permit principle algorithmically in Wyre, enabling gasless payment approvals and facilitating future-based payments for recipients, demonstrating a commitment to optimizing transaction efficiency in the blockchain payroll system. crafted and thoroughly tested three smart contracts for Wyre, contributing to the seamless functionality and security of the on-chain payroll system. Produced a comprehensive portfolio of over 20 meticulously crafted and tested smart contracts within an 11-month timeframe, showcasing a consistent commitment to delivering high-quality blockchain solutions. Led the development of a robust backend system using ExpressJS and MongoDB, complementing blockchain functionalities and ensuring seamless integration for optimal performance. Successfully deployed more than 8 contracts to Ethereum, Polygon, and Avalanche mainnets, along with over 15 contracts to their respective testnets, showcasing versatility in implementing and testing blockchain solutions across multiple networks.

Pioneered six contributions to TheAlgorithms/Solidity by introducing core math contracts and functions, facilitating seamless calculations of shares or percentages of funds and tokens, and enhancing compatibility with defi protocols. Conceptualized, designed, and deployed a notable portfolio of 180-200 smart contracts on Ethereum and Polygon blockchains, leveraging Solidity, Python, and Brownie, with a highlight being the creation of the $Aguia token —an ERC20 implementation, even amid challenges such as the deprecation of the Rinkeby testnet. Showcased expertise by participating in the Damn Vulnerable Defi CTF, uncovering and addressing five exploits, demonstrating a keen understanding of decentralized finance security vulnerabilities. Demonstrated a profound understanding by comprehending and conceptualizing the uniswapv2 liquidity pool codebase while contributing to the development of two contract projects. Executed the implementation of the Uniswapv2 codebase in a development project, successfully creating a liquidity pool for two custom tokens, showcasing proficiency in decentralized finance protocols.
