Experience

• See https://portfolio.leeclagett.com (Monero core, boost::spirit, boost::fusion, and more)

• Worked on monero core, monero wallet, and monero-lws maintenance
• Added load-balanced remote wallet scanning via custom TCP/ASIO protocol to monero-lws
• Added SSL and optional authentication to monero p2p connections (under review)
• Replaced two serialization systems within monero core with a new DOMless parser and writer for better performance and security (under review).
• Added webhooks/ZeroMQ/RabbitMQ notifications to monero-lws for received coins

• Worked on monero core, monero-wallet, MyMonero backend (Go/C++), and created monero-lws (multi-threaded multi-wallet scanner with REST API and LMDB backend written in C++)
• Implemented Dandelion++ (p2p transaction privacy) in Monero core using boost::asio
• Performance improvements to mymonero backend wallet scanning - including assembly modifications to cryptography library
• Added ZeroMQ Pub support in monero core for notification of new blocks and transactions
• Added HTTP digest AUTH to RPC in monero core using boost::spirit for parsing

• Improved and fixed bugs in the design/implementation of the local userspace filesystem (Windows, OSX, Linux) emulation used to store data on the SAFE P2P network
• Reviewed and found some issues with design/implementation (partial listing):

• Unauthenticated AES-CFB with key/IV-reuse for DataMap encryption
• File modifications could unintentionally leak related/neighbor block information due to the hashing and XOR process used during convergent encryption

• Core designer and developer of three high-performance multi-threaded applications in C++

• Met customer requirements for quarterly releases using agile development

• Profiled and improved performance of applications with callgrind, perf-tools, etc.
• Implemented proprietary client / server protocols using boost::asio

• Created web-based and standalone Python application for generating rapid7 reports
• Implemented a web-based PHP utility enabling Virginia Tech students and staff to conduct vulnerability scans of their personal machine using Nessus
