Lennox7384/README.md

Hi, I'm Lennox

A recent Computer Science graduate (Data Analytics minor) building toward DeFi and smart contract security. I have hands-on experience building safety-critical simulations, full-stack web applications, and data-driven systems, and I approach engineering with a focus on reliability and failure modes.

What draws me

I gravitate toward problems where reliability really matters: systems that fail loudly and expensively when they are wrong. Smart contract security is the sharpest form of this problem. The code is immutable on deployment, faces adversaries, and a single oversight costs huge sums.

Currently Focus

Working through the Cyfrin Updraft Solidity and DeFi curriculum, with a focus on writing secure, auditable smart contracts and understanding common attack vectors.

Stack

  • Languages: Java, C, JavaScript, Python, PHP, SQL, R
  • Web: React 19, Vite, vanilla HTML/CSS/JS
  • Systems: Linux, POSIX processes/threads/semaphores
  • Testing: JUnit, vitest, pytest
  • Practice: Fault Tree Analysis, tests as specifications, reproducible analysis pipelines, MySQL/MariaDB administration
