What I'm looking for

I am looking for a role that challenges my skills in blockchain technology and allows for mentorship opportunities while fostering innovation and collaboration.

I am a hands-on, goal-oriented technology professional with over 7 years of experience in blockchain development, particularly in building and optimizing smart contracts using Solidity. My analytical mindset and problem-solving abilities have allowed me to tackle technical challenges effectively, mentor junior developers, and deliver successful products worldwide.

At ConsenSys, I lead the development of Solidity smart contracts, focusing on performance and gas optimization. My efforts have led to significant cost savings, including a 41% reduction in average gas costs, saving over $780K annually. I take pride in creating innovative solutions, such as a unique Solidity library that increased code reuse and reduced audit findings by 23%.

Throughout my career, I have developed decentralized applications and smart contracts for various clients, including DeFi protocols and NFT platforms. My work has consistently improved product adoption and release stability, demonstrating my commitment to excellence in blockchain technology.
