Hi 👋, I'm Ian Tozer!

I'm a full-stack developer & smart contract auditor.

I program in Golang, Solidity, Rust, JavaScript, and occasionally in Python.

I like to use the following 5-step approach:

  1. Evaluate, Simplify, and Refine Requirements
  2. Delete Parts or Process Parts
  3. Simplify or Optimize
  4. Iterate faster
  5. Automate

Development

  • Portfolio: Selected works below
  • Sports Arbitrage Bots: Developing high-performance trading systems that identify and capitalize on cross-platform odds differentials in real-time
  • DeFi and DAO Governance: Collaborating on exceptional decentralized financial and governance infrastructure
  • Code Visualization: Creating static and dynamic code maps using Rust-based force-directed graph algorithms to visualize complex codebases
