• Implemented core infrastructure for Ethereum-based blockchain platform written in Haskell, delivered

new features and bug fixes in bi-weekly sprints reported directly to the Director of Engineering, and

presented production-ready changes to the company through internal demonstrations

• Architected an on-chain identity system using X.509 certificates to identify network validators and

administrators, constructed Solidity language features to complement user identity features and access

identity information, and documented internal processes and new language features for public use

• Designed the smart contract architecture behind the flagship marketplace dApp (Mercata) that helps users

buy/sell real world assets by representing assets and sales as on-chain contracts and implemented related

changes to the public REST API JavaScript library that supported all applications on the ecosystem

• Built a third-party MetaMask payment server to facilitate USDT and ETH transactions on the marketplace

dApp that handled over $300,000 in revenue over a single quarter after its release with a 98% uptime

• Optimized memory usage across the platform, reducing usage by over 60% using Haskell compiler

optimizations to speed up SQL queries, minimizing disk space of blockchain data stored by 20%, boosting

smart contract code execution by 45%, and reducing redundant network traffic by 30% in a decentralized

peer-to-peer network
